用于调度无线通信网络中的终端的方法和对应基站 A method for scheduling a wireless communication network terminals and the corresponding base station

技术领域 Technical Field

[0001] 本发明涉及一种用于调度无线通信网络中的终端的方法。 [0001] The present invention relates to a method for scheduling in a wireless communication network terminal. 背景技术 Background

[0002] 无线通信网络中的公共调度包括在知道不会向预定义区域中的两个终端分配相同资源以免干扰的情况下定义可以例如在频率、时间或者代码上分离并且向终端分配的不同资源。 [0002] The wireless communication network including the definition of common scheduling different resources may, for example separation in the know will not allocate the same resources to a predefined area so as not to disturb the two terminals on the frequency, time, or code, and assigned to a terminal .

[0003] 在近来的无线通信网络中并且尤其为了增加吞吐量和效率,已经提出使得能够同时在单个资源上调度预定义区域中的多个终端的方法。 [0003] In recent wireless communication network and in particular in order to increase the throughput and efficiency have been proposed making it possible to simultaneously dispatch a predefined area of the plurality of terminals on a single resource method. 主要问题包括适当选择可以向其分配相同资源的终端以便限制同时使用相同资源的终端在系统中引起的相互干扰。 The main problem to which the terminal can be suitably selected include allocating the same resources at the same time in order to limit mutual interference caused by the terminal using the same resources in the system. 尤其在具有频率重用1的多蜂窝部署中,在小区边界经历强干扰。 In particular, with a frequency reuse multi-cell deployment 1, undergo strong interference at the cell boundary. 可以通过协调在相互接近的扇区中的传输来减少这一干扰。 Close to each other can be coordinated in the transport sector through to reduce this interference. 用于选择可以在相同资源上调度的终端的标准例如将终端在小区中的位置以及在多个天线基站使用波束成形算法来生成单独波束的可能性纳入考虑之中。 The criteria for selecting a terminal may be scheduled on the same resource, for example, the location of the terminal in the cell, and a plurality of antennas in the base station using beam forming algorithm to generate the possibility of separate beams into consideration. 更一般而言,在邻近扇区中在相同资源上仅调度来自/去往造成低相互干扰的终端的传输。 More generally, in neighboring sectors on the same transmission resource scheduling only from / to interfere with each other resulting in low terminals.

[0004] 存在具有集中协调的调度算法,但是这些算法的弊端在于需要在中心实体与需要协调的基站之间的大量信令。 [0004] having a centrally coordinated scheduling algorithms exist, but the shortcomings of these algorithms is that the center needs a large number of signaling entity and the need for coordination between base stations. 尤其需要向中心实体转发在终端与基站之间的全部信道条件,需要向中心实体转发全部BS调度请求。 In particular, the central entity needs to be forwarded between the terminal and the base station all channel conditions, needs to be a central entity forwards all BS scheduling request. 另外,调度延迟可能为高。 Furthermore, the scheduling delay may be high.

[0005] 本发明的一个具体目的在于提供一种与上述集中选项相比效率更高而信令减少的调度算法。 [0005] A specific object of the present invention is to provide a centralized above options higher and signaling efficiency reduce scheduling algorithms compared.

[0006] 本发明的另一目的在于提供一种适于执行该调度方法的基站。 [0006] It is another object of the present invention is to provide a method adapted to perform the scheduling of the base station. 发明内容 DISCLOSURE

[0007] 通过根据权利要求1所述的一种用于调度无线通信系统中的传输的方法和根据权利要求8所述的一种基站来实现这些目的和下文出现的目的。 [0007] According to one by a wireless communication system for scheduling transmission method according to any one of the object and a base station according to claim 8 appears to achieve these objectives and the following claims.

[0008] 根据本发明,调度机制是一种限于基站近邻的局部分布调度方案。 [0008] According to the present invention, the scheduling mechanism is a limited local distribution scheduling scheme neighbor station. 具体而言,调度机制使用在位于预定义区域中的基站之间的优先级,该调度由预定义区域中的优先级最高的基站开始,该调度然后由优先级第二高的基站将优先级更高的基站执行的调度纳入考虑之中的情况下继续,并且以此类推。 Specifically, the scheduling mechanism uses a predefined area located between the base station priority, the schedule starting from a predefined area of highest priority base station, the scheduling priority and then by the second highest base priority Higher base station performs scheduling into consideration the case continues, and so on.

[0009] 在一个优选实施例中,使用在预定义区域中的基站之间的分配调度优先级的循环改变来恢复在这一区域中的所有基站之间的公平。 Scheduling priorities change cycle [0009] In a preferred embodiment, the use of a predefined area between base stations to restore fairness in this area all the base station.

[0010] 这带来的优点在于减少集中调度机制为了建立包括在系统范围内的所有信道具体信息的共同数据库而需要的大量信令开销并且保持该共同数据库一致和最新。 [0010] This brings the advantage is to reduce the centralized scheduling mechanisms include all channels in order to establish a system-wide common database of specific information and require a large number of signaling overhead and keeping the common database consistent and up to date.

[0011] 根据本发明的另一方面,调度是基于扇区内和扇区间的基站/终端信道具体信息(例如CQI、SINR、上行/下行路径损耗、用于最好和最坏传输条件的预编码矩阵索引(PMI)、...)以及这样的信道具体信息在邻近基站之间的交换。 [0011] According to another aspect of the present invention, the base station based on the scheduling between sectors within the sector and / terminal channel specific information (e.g. CQI, SINR, uplink / downlink path loss, for the best and worst transmission conditions pre- coding matrix index (PMI), ...) as well as specific information such channels between adjacent base stations exchange. 这些信道具体信息允许基站检测相互干扰可能性高的终端并且在不同资源上调度这样的终端以免对它们的传输造成高干扰影响。 These channel specific information allows the base station to detect a high probability of interference between the terminal and the scheduling of such terminals on different resources in order to avoid high interference on their transmission.

[0012] 这带来的优点在于将用于调度用途的相关信息仅分发给需要它们的基站。 [0012] This brings the advantage that the relevant information for scheduling purposes only distributed base stations that need them. 这也有助于保持信令负荷小到足以实现无线通信系统中的良好性能。 This also helps to keep the signaling load is small enough to achieve a good wireless communication system performance.

[0013] 这一算法与集中机制对照的另一优点在于在协调边界无冲突,因为协调边界根据本发明为重叠。 [0013] Another advantage of this method lies in the centralized control mechanism to coordinate border conflict, according to the present invention because coordination boundary overlap.

[0014] 在从属权利要求中定义了本发明的更多有利特征。 [0014] defines more advantageous features of the invention in the dependent claims. 附图说明 Brief Description

具体实施方式 DETAILED DESCRIPTION

[0022] 本领域技术人员将理解,根据本发明的调度方法以及对应基站可以应用于不同无线系统,尤其是遵循WiMAX标准或者3G LTE (3G长期演进)标准的那些系统。 [0022] Those skilled in the art will appreciate that the scheduling method according to the present invention can be applied to a base station and a corresponding different wireless systems, in particular following the WiMAX standard or 3G LTE (3G Long Term Evolution) standard those systems.

[0023] 图1示出了根据本发明的用于局部分布调度机制的在每个基站周围的预定区域。 [0023] Figure 1 illustrates a predetermined area according to the present invention for topical distributed scheduling mechanism around each base station. 图1示出了服务120扇区的基站BS。 Figure 1 shows a 120 sector serving base station BS. 在这一实施例中,3个120扇区共同定位。 In this embodiment, the three 120 sectors co-located. 对于每个扇区,根据本发明确定区域以便实施局部分布调度算法。 For each sector, in accordance with the present invention to determine the local distribution of the region in order to implement the scheduling algorithms. 例如,区域Al和A2分别对应于直接包围扇区Sl和S2的扇区集。 For example, the regional Al and A2 respectively corresponding to the immediately surrounding the sector Sl and S2 sectors set. 在这一例子中,区域除了考虑的扇区之外还包括6个扇区。 In this example, in addition to considering the sector region further comprises six sectors. 根据考虑的扇区,也将不同区域纳入考虑之中。 According to consider the sector, will also be taken into consideration in different regions.

[0024] 在这一例子中示出了扇区的六边形结构,但是本发明并不限于这样的结构。 [0024] In this example is shown of a hexagonal structure of the sector, but the present invention is not limited to such a structure.

[0025] 本领域技术人员将清楚,根据本发明的方法可以应用于扇区的几何形状与在图1 中呈现的几何形状不同的无线通信网络中。 [0025] will be apparent to those skilled in the art, according to the method of the present invention may be applied to the sector geometry and the geometry presented in FIG. 1 in different wireless communication networks. 尤其有可能在每个基站周围具有不同数目的扇区或者在基站周围具有不同扇区几何形状类型。 In particular, it is possible to have a different number of sectors around the base station or surrounding base stations each having a different sector types of geometries.

[0026] 下文还将说明如何使用根据本发明局部分布调度机制来调度位于区域中的终端。 [0026] The following will explain how to use according to the present invention locally distributed scheduling mechanism to schedule located in the area of the terminal.

[0027] 在BSl的扇区1中的Txl和BS2的扇区2中(其中扇区1和扇区2是相邻扇区) 的Ty2这两个不同终端干扰,因为例如它们位于相同扇区边界,从而BSl向Txl发送的数据干扰Ty2在相同帧资源(例如相同时隙(相同时间和相同频率位置))上从BS2接收的数据。 [0027] In BSl Txl sector 1 and sector 2 in BS2 (sector 1 and sector 2 wherein adjacent sector) interference Ty2 two different terminals, they are located in the same sector as e.g. border, so that the data sent BSl to Txl Ty2 interference in the same frame resources (such as the same time slot (same time and same frequency location)) on the data received from BS2.

[0028] 可以在BS2向位置远离Txl的另一Tz2发送数据同时BSl向Txl发送数据并且两个BS使用波束成形以将它们的数据束仅引向预期目的地时使干扰最小。 [0028] BSl can simultaneously send data to another Tz2 BS2 transmit data to a location remote from Txl Txl and both BS using beamforming to be directed only at their intended destination data bundle minimizing interference. 两个BS可以同时使用相同帧资源,并且它们未产生干扰或者仅产生至少有限干扰。 Two BS can use the same resource frame, and they did not interfere with, or at least only produce limited interference.

[0029] 图2a_2c示出了根据本发明的调度算法的一种实施方式。 [0029] FIG 2a_2c illustrates one embodiment of the scheduling algorithm according to the present invention. [0030] 与现有技术的解决方案相反,没有中心调度器用来协调在相邻扇区之间的调度。 [0030] and the prior art solutions contrary, there is no central scheduler to coordinate scheduling between adjacent sectors. 每个扇区/基站仅协调与它的相邻扇区/基站的调度。 Each sector / base station only in coordination with its adjacent sectors / base stations scheduling.

[0031] 根据本发明,使用一种使用优先级的分级调度方法,其中最高优先级的调度器(调度优先级A)在可用资源上调度在它的覆盖之下的第一终端,并且此后其它调度器(调度优先级B或者C)在将所有更高优先级的调度器的结果纳入考虑之中(B将A的结果纳入考虑之中;C将A和B的结果纳入考虑之中)的情况下按照调度优先级递减的顺序(B在C 之前)在资源上调度在它们的覆盖之下的终端。 [0031] According to the present invention, a method of using hierarchical priority scheduling method, wherein the highest priority scheduler (scheduling priority A) on the available resources in the scheduling of the first terminal under its coverage, and thereafter the other scheduler (scheduling priority B or C) will all result in higher priority scheduler into consideration (B A results into consideration; C to A and B results into consideration) of the case of the scheduling order of decreasing priority (B before C) scheduling under their coverage of the terminal on the resource.

[0032] 在一个方面,在相同资源上的调度将引起预定义阈值以上的干扰的情况下,分别具有调度优先级B和C的基站决定在与分别具有调度优先级A和B的基站已经调度的资源不同的资源上调度。 Case [0032] In one aspect, scheduled on the same resource will cause a predefined threshold above interference, each having scheduling priority B and C of the base station determines with each having scheduling priority A and B of the base station has scheduling scheduling of resources on different resources.

[0033] 另一方面,在相同资源上的调度将引起预定义阈值以下的干扰的情况下,分别具有调度优先级B和C的基站可以决定在与分别具有调度优先级A和B的基站已经调度的资源相同的资源上调度。 Case [0033] On the other hand, scheduled on the same resources will cause interference predefined threshold value respectively have scheduling priority B and C of the base station can decide with each having scheduling priority A and B of the base station has on the same resource scheduling resource scheduling.

[0034] 作为例子,下文假设每个扇区需要一个帧以调度它的帧并且向所有邻居传送它的帧布局,即每个扇区的调度类型随着帧而变化。 [0034] As an example, this article assumes that each sector needs a frame to dispatch its frame and transmits its frame layout to all neighbors, namely scheduling type of each sector varies with the frame. 如果通信和计算需要多个帧或者如果可以在单个帧中执行完整调度计算(所有调度优先级)和通信,则该机制也起作用。 If the communications and computing requires multiple frames or if you can perform a complete scheduling computing in a single frame (all scheduling priority) and communication, the mechanism also plays a role.

[0035] 本领域技术人员将清楚,根据本发明的方法对多于或者少于3个调度优先级的情况同样起作用。 [0035] It will be apparent to those skilled in the method according to the invention of more or less than three scheduling priority works similarly to the case. 3个调度优先级将不视为本发明的限制因素。 3 scheduling priority will not be considered as a limiting factor of the present invention.

[0036] 如图加中所示,协调调度始于互不干扰(这例如因为它们并非直接相邻)的具有调度优先级A的一些扇区。 [0036] As shown in FIG plus, coordinated scheduling starts interfering (which, for example because they are not directly adjacent) has a scheduling priority A number of sectors. 选择这些扇区是因为它们的相互距离保证低相互干扰,或者出于除了相互之间的距离之外的原因而未干扰的扇区可以同时为调度优先级A。 Choose these sectors because of their distance from each other to ensure low interference with each other, or in addition to the sector for the distance between each other without interference reasons can simultaneously scheduling priority A.

[0037] 具有调度优先级A的扇区为不远将来的帧N或者帧N的部分生成帧布局。 [0037] A having a scheduling priority sector generates a frame layout for the near future frame N or N frame portion.

[0038] 然后,具有调度优先级A的扇区向具有调度优先级B和调度优先级C的所有相邻扇区发送帧布局N。 [0038] Then, with a scheduling priority sectors A transmission frame layout to all neighboring sectors have scheduling priority scheduling priority B and C of N.

[0039] 如图2b中所示,具有调度优先级B的扇区(这些扇区同样并非彼此直接相邻)通过以它们的突发未干扰在具有调度优先级A的扇区的帧布局N中的突发这样的方式放置它们的突发来为帧N或者帧N的部分生成帧布局。 [0039] As shown in Fig. 2b, B having the scheduling priority sectors (the sectors also not directly adjacent to each other) by not interfering in their burst layout having frame scheduling priority sectors A N The burst in such a way as to put them in a burst frame or partial frame N of N frames generated layout.

[0040] 最后,具有调度优先级B的每个扇区向类型C的相邻扇区发送它的帧N/帧部分布局N。 [0040] Finally, having a scheduling priority for each sector B transmits it to the type C adjacent sectors frame N / layout frame portion N.

[0041 ] 如图2c中所示,具有调度优先级C的扇区最后通过以它们的突发未干扰在具有调度优先级A和B的扇区的帧N/帧部分布局N中的突发这样的方式放置它们的突发来为帧N/帧N的部分生成帧布局。 [0041] As shown in Fig. 2c, having a sector C scheduling priority by the last burst does not interfere with their scheduling priority having sectors A and B burst frame N / N in the layout frame portion place them in such a way to generate a burst of a frame portion of a frame layout N / N of the frame.

[0042] 当需要空中发送帧N或者帧N的部分时,每个扇区根据它的预先计算的布局N向它的帧N填充那时需要发送的数据。 [0042] When the required air transmission frame or partial frame N N, the data for each sector based on its pre-calculated distribution frame to its N N filling time needed to send.

[0043] 在这一实施例中,假设在所有扇区之间同步帧编号。 [0043] In this embodiment, the frame number is assumed that the synchronization between all sectors. 可选地,每个扇区知道对它的每个相邻扇区的帧偏移也足够了。 Alternatively, each sector knows its frame offset each adjacent sector is enough.

[0044] 图3示出了根据本发明的在属于预定区域的基站之间的调度优先级变化。 [0044] FIG. 3 shows the priorities vary according to the area between the base station belonging to a predetermined schedule of the present invention.

[0045] 为了保证在扇区之间的公平,在往复循环中向每个扇区等同地分配每个调度优先级(A,B,C)。 [0045] In order to ensure fairness between sectors, and in the cyclical allocated equally to each sector in each scheduling priority (A, B, C). [0046] 每个扇区获得随着帧而变化的可变调度优先级A、B或者C,即根据当前帧编号和固定帧生成ID,在每个帧中向扇区分配调度优先级A、B或者C。 [0046] Each sector obtained varies with the variable frame scheduling priority A, B or C, i.e., the current frame is generated ID number and the fixed frame, the scheduling priority assigned to sector A in each frame, B or C. 例如,如图3中所示,可以在帧X-2和1中向一个扇区分配调度优先级A、在帧XI和2中分配调度优先级C、在帧X 和3中分配调度优先级B、...。 For example, as shown in Figure 3, can be a priority in the frame A 1, X-2, and scheduling to a sector allocation in the frame XI and 2 scheduling priority C, X and 3 in the frame scheduling priority B, ....

[0047] 在帧X-2在具有调度优先级A的扇区中的传送期间、在帧XI在具有调度优先级B的扇区中的传送期间以及在帧X在具有调度优先级C的扇区中的传送期间计算帧1。 [0047] During the transport frame X-2 in the A's have scheduling priority sectors in the frame having a transfer during the XI scheduling priority sectors in the B and X in the frame having scheduling priority C fan calculating the frame 1 during the transfer zone. 最后,具有调度优先级A、B和C的扇区同时发送帧1。 Finally, having a scheduling priority A, B and C of the transmission frame 1 while the sector. 这一机制用于计算和发送所有后续帧 This mechanism is used to calculate and send all subsequent frames

[0048] 该调度按照调度优先级顺序由对应基站依次执行,其中在接收到调度优先级更高的基站的调度决定时发生在调度优先级更低的基站的调度。 [0048] The scheduling according to a scheduling priority order of execution by a corresponding base station, which at the time received a higher scheduling priority scheduling decisions station occurred in a lower scheduling priority scheduling base station.

[0049] 尤其可以在连续帧期间或者如果有可能在单个帧的过程期间向其它基站发送调度决定则在帧的连续部分期间完成调度决定。 [0049] In particular, during the successive frames can or if possible during the course of a single frame to other base station transmits the scheduling decisions during the continuous portion of the frame to complete the scheduling decision. 尤其是如果可以独立于数据消息发送信令消息,则可以针对待发送的下一帧完成全部调度而无需如在图3中描述的3帧时间延迟。 Especially if the data message is sent independently of signaling messages, it is possible to complete all of the scheduling for the next frame to be transmitted without time such as 3 in FIG. 3 described delay.

[0050] 本领域技术人员将理解,如果在对应无线通信网络中定义子帧结构,则也可以在子帧级发生优先级变化。 [0050] Those skilled in the art will appreciate that if you define the corresponding sub-frame structure in a wireless communication network, you can also change the priority occur in the sub-frame level. 取而代之,可以仅每F个帧发生优先级改变。 Instead, it can only take place every F frames priorities change.

[0051] 图4示出了根据本发明的调度方法的一种实施方式的流程图。 [0051] FIG. 4 shows a flow chart of a scheduling method according to an embodiment of the present invention.

[0052] 在初始化期间或者按照自组织方法,将向每个扇区分配固定帧生成ID。 [0052] During the initialization or method according to self-organization, it will be allocated for each sector fixed frame generation ID.

[0053] 除了在初始化时之外,每个基站还获得所有周围相邻扇区的列表(具有它们的对应帧生成ID)。 [0053] In addition to the outside of the initialization, each base station may also get a list of all the surrounding neighboring sectors (with their corresponding frame generation ID).

[0054] 在步骤41,使用帧生成ID和帧编号,每个扇区可以确定它的当前调度优先级A、B 或者C,并且它可以在当前帧期间确定它需要为哪个将来帧N生成帧布局N。 [0054] In step 41, using the frame ID and frame number is generated, each sector may determine its current scheduling priority A, B or C, and it may be determined that it needs to generate a frame to which the future frame in the current frame N during Layout N.

[0055] 在步骤42,扇区根据在步骤41计算的调度优先级来应用不同调度。 [0055] step 42, step 41 calculates the sector according to the scheduling priority to apply different scheduling.

[0056] 在步骤43A,具有调度优先级A的扇区计算将来帧布局N作为主布局,因为它具有最高可能调度优先级A。 [0056] In step 43A, having a sector A scheduling priority calculation future frame N as a main distribution arrangement, because it has the highest possible priority scheduling A.

[0057] 在步骤43B,具有调度优先级B的扇区在考虑已经向具有调度优先级B的扇区报告帧布局的在它的区域中的具有调度优先级A的相邻扇区的结果之后计算将来帧布局N。 After [0057] In step 43B, with the result of the scheduling priority sector B has been considered to have a scheduling priority B frame layout of the report of the sector in its region having the scheduling priority of the adjacent sectors A calculate future frame layout N.

[0058] 在步骤43C,具有调度优先级C的扇区在考虑已经向具有调度优先级C的扇区报告帧布局的在它的区域中的具有调度优先级A和B的相邻扇区的结果之后调度帧N。 [0058] In step 43C, it has a scheduling priority sector C has been considered to neighboring sectors have scheduling priority sector C frame layout of the report in its region having scheduling priority A and B of the Results after the schedule frame N.

[0059] 在步骤44A,具有调度优先级A的扇区向它的区域中的具有更低调度优先级B和C 的扇区发送它已经计算的帧布局。 [0059] In step 44A, having a sector A scheduling priority to its regions having a lower scheduling priority sectors B and C has its transmission frame layout calculation. 可以使用信令来发送帧布局。 You can use the signaling transmission frame layout. 可以包括在不同可用资源上调度的终端的标识符或者仅包括关于调度终端类型的指示。 It may include an identifier on different terminals available resource scheduling or only an indication of dispatch terminal type. 一般而言,描述用于将来帧N的帧布局的信息针对这一帧布局中的每个资源(例如WiMAX帧中的每个时隙)包括占用这一帧资源的终端编号。 Generally, the description information for future frame N frame layout for the layout of the frame of each resource (e.g., WiMAX frame each slot) of the frame comprises a resource occupancy number of the terminal.

[0060] 为了减少帧中的终端编号数目,生成帧布局的BS可以将具有相似角度和路径损耗的终端组合成一组并且通过一个终端编号来代表该组。 [0060] In order to reduce the number of terminals numbered frames, BS may generate a frame having a layout similar path loss and angles are combined into a set terminal and a terminal ID is represented by the group. 当以后发送计算的帧时,每次分配对多个终端的这一分组也给予更多数据发送灵活性。 When the frame is calculated to be sent later, each group assigned to the plurality of terminals are given more flexibility in data transmission.

[0061] 为了减少信令开销,可以用压缩形式描述相同终端编号所占用的资源,例如描述在相同终端所占用的帧中的资源区域。 [0061] In order to reduce signaling overhead, can be described in the form of compressed resource occupied by the same number of terminals, such as those described in the frame the same resource region occupied by the terminal.

[0062] 为了减少信令开销,如果使用探测来获得信道具体信息,则终端编号可以简单地 [0062] In order to reduce signaling overhead, if you use the channel specific probe to obtain information, the terminal number can be easily

6由扇区Ax中的探测位置编号代表。 6 by the sector in the probe position Ax number represents.

[0063] 用于DL帧的帧布局还应当包含DL发送功率。 [0063] DL frame for frame layout should also contain DL transmission power. 如果执行DL功率控制,则需要提供DL帧布局中每一终端的DL发送功率值,否则需要提供每一BS的DL发送功率值。 If you do DL power control, you need to provide transmission power value DL DL frame layout for each terminal, or the need to provide for each BS DL transmit power value.

[0064] 在步骤44B,具有调度优先级B的扇区向它的区域中的具有更低调度优先级C的扇区发送它已经计算的帧布局。 [0064] In step 44B, having a scheduling priority sector B transmits its frame layout already calculated in the region of its sector C having a lower priority in the scheduling.

[0065] 在步骤45A,具有调度优先级A的扇区向将在下一帧中发送的帧布局中插入数据。 [0065] In step 45A, having a sector A scheduling priority frame layout to be sent in the next frame of data to insert.

[0066] 在步骤45B,具有调度优先级B的扇区向将在下一帧中发送的帧布局中插入数据。 [0066] In step 45B, with the sector scheduling priority B frame layout to be sent in the next frame of data to insert.

[0067] 在步骤46A,具有调度优先级A的扇区发送当前帧。 [0067] In step 46A, the sector has a scheduling priority A transmission of the current frame.

[0068] 在步骤46B,具有调度优先级B的扇区发送当前帧。 [0068] In step 46B, it has a scheduling priority sector B transmits the current frame.

[0069] 在步骤46C,具有调度优先级C的扇区发送当前帧。 [0069] In step 46C, it has a scheduling priority sectors C to send the current frame.

[0070] 图5示出了根据本发明的信道具体信息收集的一种可能实施方式。 [0070] FIG. 5 shows a channel according to the present invention is to collect specific information possible implementations. 为了发现哪些终端可能干扰,可以使用协调探测来获得在BS与服务扇区中的终端之间的信道信息并且获得在BS与所有相邻扇区中的终端之间的信道信息。 To find out which terminal may interfere with the channel information, can be used to coordinate the probe in BS and service sectors between the terminal and the terminal channel information obtained BS and all between adjacent sectors. 信道信息在BS从终端接收信号时例如意味着方向和接收功率,其中该信号可以是原来向BS寻址的数据或者在BS接收原来向另一BS寻址的非预期信号时可能是干扰。 May be interfering channel information when the BS receives a signal from a terminal such as mean received power and direction, wherein the original data signal may be addressed to the BS or the receiving BS originally addressed to another non-desired signal at the BS.

[0071] 下文在WiMAX无线通信网络的背景中进行描述。 [0071] are described below in the context of WiMAX wireless communication network. 这将尤其从通过协调探测来获得信道具体信息的方式中变得清楚。 This will become apparent in particular from the channel to obtain specific information through coordinated detection mode. 为了执行协调探测,7个扇区的区域形成协调探测扇区组,其中仅一个扇区在一个帧期间探测,即仅在一个扇区中的终端发送探测信号。 In order to perform coordinate detection area 7 sectors forming a sector group coordinated sounding, wherein only one sector detected during a frame, i.e., only in one sector of the terminal transmits the sounding signal. 在探测扇区中的BS和在属于探测组的所有相邻扇区中的BS接收探测信号并且生成信道信息表TBS。 BS in detecting sector and all adjacent sectors belonging to detect the BS group received probe signal and generating channel information table TBS. 然后,每个BS向所有它的相邻扇区发送它的信道信息表。 Then, each BS transmits its channel information sheet to all its neighboring sectors. 本领域技术人员将理解,如果仅表的部分包括用于相邻基站的相关信息则也可以发送表的部分。 Those skilled in the art will appreciate that if part of the table includes only the relevant information for neighbor base stations are part of a table to be sent. 也可以在大量选项之中选择用于发送表的格式。 You can also select the format for sending a large number of options among tables.

[0072] 在协调调度阶段中,基站使用信道信息表,从而每个基站通过将可能对相邻扇区中的终端有干扰的终端的突发放入与那些邻居不同的帧资源中(即回顾图1,通过向BS2的二维帧的与相邻扇区中的Txl在BSl的二维帧中已经占据的资源位置不同的位置分配Ty2 的下行突发)来为它们负责的扇区生成帧布局。 [0072] In the coordinated scheduling stage, those neighbors burst into a different frame resource base station using the channel information table to each base station by the neighboring sectors may interfere with a terminal end (ie Review Figure 1, downlink burst allocation Ty2 by location adjacent to the resource sector in the two-dimensional frame BSl Txl already occupied BS2 in a two-dimensional frame of different positions) to be responsible for their sector to generate a frame layout. 二维帧意味着它们具有时间和频率扩展。 Dimensional frame means that they have the time and frequency extension. 这尤其用于如在3G LTE或者WIMAX无线通信系统上使用的0FDM/0FDMA。 This is particularly useful as in 3G LTE or WIMAX wireless communication system using the 0FDM / 0FDMA. 本发明决不限于在二维帧结构中使用。 The present invention is not limited to use in a two-dimensional frame structure.

[0073] 在初始化期间或者通过自组织方法,每个扇区接收如下参数,这些参数与实际帧编号一起允许扇区确定它的实际探测状态(活跃探测或者监听相邻扇区)及其实际调度优先级A、B或者C。 [0073] or by the method of self-organization, each sector receives the following parameters, which together allow the actual frame number of sectors during initialization to determine its actual detected status (active or detection monitor neighboring sectors) and the actual scheduling Priority A, B or C. 在初始化期间或者通过自组织方法,将向每个扇区分配固定探测ID[S0, Sl,. . . S6]。 During initialization, or by self-organizing methods, each sector will be assigned a fixed probe ID [S0, Sl ,... S6]. 利用探测ID和帧编号,每个扇区可以确定活跃探测帧编号,即在允许这一扇区探测它的终端时的帧编号。 Utilizing probe ID and frame number, each sector may determine active probe frame number, i.e., allowing the sector to detect its terminal frame number.

[0074] 在协调探测扇区组(CSSG)中,探测信号为正交,例如仅一个CSSG成员在一个帧期间探测。 [0074] In the coordinate detection sector group (CSSG), the detection signal is orthogonal, for example, only one member CSSG detected during one frame. 0556的每个成员获得唯一探测10[50,51,...56]。 Each member of the 0556 probe obtained the sole 10 [50, 51, ..., 56]. 如图5中所示,具有探测ID S2 的扇区在帧2、9、16...期间执行探测。 It is shown in Figure 5, having a sector ID S2 perform detection probe 2,9,16 ... frame period. 具有探测ID 34的扇区在帧4、11、18...期间执行探测。 Sector having probe ID 34 of the probe occurs frame 4,11,18 ... period.

[0075] 在探测期间获得在如下信道与BS之间的信道信息: [0075] During the probe in between following the channel with the BS channel information:

[0076] 在探测扇区X中的所有终端与在探测扇区X中的BS (存储于TB& ;x中)。 [0076] • All terminal and BS in detecting the sector X in X in the sector in the probe (stored in the TB &; x in). [0077] 在探测扇区X中的所有终端与在所有相邻扇区Y中的BS(存储于TBSy;x中)。 [0077] • All terminal and BS in detecting the sector X in Y in all neighboring sectors (stored in TBSy; x in).

[0078] 优选地,信道信息存储于探测表TBSy ;x中,其中X为探测扇区而Y为接收探测信号的扇区。 [0078] Preferably, the channel information is stored in the probe table TBSy; x, in which X and Y for the detection of the sector to receive the probe signal of the sector.

[0079] 优选地,每个扇区X存储并且也向它的对应区域中的所有它的相邻扇区Y报告表TBSx ;X 禾Π TBSx ;γ ο [0079] Preferably, each sector X memory and also to its corresponding area in all of its adjacent sectors Y Report Form TBSx; X Wo Π TBSx; γ ο

[0080] 例如,表ΤΒ&;Χ包含针对扇区X中的每个终端(通过探测分配来代表)的以下测 [0080] For example, Table ΤΒ &; Χ X contains the following test for the sector in each terminal (represented by probing allocated)

[0084] 例如,表TBSY;X包含针对扇区X中的每个终端(通过探测分配来代表)的以下测 [0084] For example, Table TBSY; X contains the following measurements for each of the terminals in sector X (represented by probing allocated)

量值: Value:

[0085] rxpwr :在BS接收的信号功率 [0085] rxpwr: received signal power at the BS

[0086] 角度:如从BS所见的接收信号方向 [0086] point of view: If the received signal as seen from the direction BS

[0087] 在具有调度优先级A的扇区中的调度: [0087] In the sector having the scheduling priority A schedule:

[0088] 由于具有调度优先级A的扇区是为将来帧N生成帧布局的最初扇区,所以在原则上每个扇区可以在仅将用于在具有调度优先级A的扇区中的所有已建立连接的业务参数(例如周期、比特速率、优先级、...)以预测将来帧N中的所需帧资源数量纳入考虑之中的情况下生成各个上行帧布局。 [0088] A scheduling priority because of the sector is the first sector of the future frame N frames generated layout, each sector so that in principle can be used only in a sector A scheduling priority with the All operational parameters of the connection has been established (e.g., period, bit rate, priority, ...) to predict the future inclusion of the required number of frames N in the case under consideration the resources frame generating respective uplink frame layout.

[0089] 为了简化具有调度优先级B、C的后继扇区的帧布局计算,推荐但是并非强制具有调度优先级A的每个扇区根据角度分类机制来调度,即它按照角度(根据表TBSax, Ax)对扇区中的终端进行分类并且按照终端编号所示顺序调度终端。 Each sector [0089] In order to simplify have scheduling priority B, C frame layout successor sector calculations, recommended but not mandatory have scheduling priority A classification mechanism according to schedule point of view, that it is in accordance with the angle (Table TBSax , Ax) terminals in the sector and are classified according to terminal number in the order shown dispatch terminal.

[0090] 当具有调度优先级A的扇区完成针对帧布局N的计算时,它向具有调度优先级B 和C的所有它的相邻扇区发送帧布局N。 [0090] When the sector having the scheduling priority A complete calculation for the N frame layout, the layout of a transmission frame to which all the neighboring sector having its scheduling priority B and C of N.

[0091] 在具有调度优先级B的扇区中的调度 [0091] Dispatched sector having scheduling priority in the B

[0092] 在为将来帧N计算帧布局之前,具有调度优先级B的扇区需要为它的每个需要将来帧中的资源的终端(由终端编号y (终端y)代表)计算偏好矩阵。 [0092] In the prior frame N calculation frame future layout, with a scheduling priority B sector needs for each of its needs in the future resources of the terminal frame (by the terminal number y (terminal y) representative) calculated preference matrix. 每个矩阵元素代表在终端y将放入帧资源中时,该帧资源的最小S^值。 Each matrix element represents y will be placed at the end frame resources, the minimum S ^ value of the frame resources.

[0093] 为了计算偏好矩阵,扇区By需要: [0093] In order to calculate the preference matrix By sector needs:

[0094]-来自具有调度优先级A的所有相邻扇区的帧N的帧布局。 [0094] - from a frame having N A scheduling priority of all neighboring sectors frame layout.

[0095]-在扇区By中生成的探测表:TBSBy,By和TBSBy,Ax(例如在图2中:TB&y,By、TB&y,A(1、 TBSBy,αϊ、TBSBy,A2) [0095] - By generated in the sector probe table: TBSBy, By and TBSBy, Ax (for example in Figure 2: TB & y, By, TB & y, A (1, TBSBy, αϊ, TBSBy, A2)

[0096]-周围扇区Ax向扇区By发送的探测表:TBSAx,Ax和TBSAx,By [0096] - the detection of sectors around the table sent to the sectors Ax By: TBSAx, Ax and TBSAx, By

[0097]-用于在具有调度优先级B的扇区中的所有已建立连接的业务参数(例如周期、比特速率、优先级、..)以预测将来帧N中的所需帧资源数量 [0097] - for all traffic connection parameters (e.g., period, bit rate, priority, .. ) in sector B having the scheduling priority in the future to predict the required number of frames of N frames resources

[0098] 用于由具有调度优先级A的扇区包围的具有调度优先级B的扇区的偏好矩阵可以计算如下: [0098] For preference matrix B have scheduling priority sector by sector having surrounded scheduling priority A can be calculated as follows:

[0099] PrefBy (资源,终端y) = Min (SIRByAx, SIRAxBy) [0099] PrefBy (resources, terminal y) = Min (SIRByAx, SIRAxBy)

[0100] 在如图2中的扇区结构的情况下,为具有调度优先级B的扇区计算的偏好矩阵可以是: [0100] In the case shown in Figure 2, the structure of the sector, to have a preference matrix scheduling priority sector B can be calculated:

[0101] PrefBy (资源,终端y) = Min (SIRByA0, SIRByA1,SIRByA2, SIRA0By, SIRA1By, SIRA2By) [0101] PrefBy (resources, terminal y) = Min (SIRByA0, SIRByA1, SIRByA2, SIRA0By, SIRA1By, SIRA2By)

[0102] SIRByA0是如果终端y占用这一资源,则By中的终端y受到的来自扇区AO中的终端X的干扰。 [0102] SIRByA0 if the terminal y occupy this resource, By the end of interference from sector y by the end of X AO.

[0103] SIRByA1是如果终端y占用这一资源,则By中的终端y受到的来自扇区Al中的终端X的干扰。 [0103] SIRByA1 if the terminal y occupy this resource, By the end of interference from sector y by the end of X Al.

[0104] SIRByA2是如果终端y占用这一资源,则By中的终端y受到的来自扇区A2中的终端X的干扰。 [0104] SIRByA2 if the terminal y occupy this resource, By the end of interference from sector y by the end of X A2.

[0105] SIRA0By是如果终端y占用这一资源,则AO中的终端χ受到的来自扇区By中的终端y的干扰。 [0105] SIRA0By interference if the terminal y occupy this resource, the AO terminal in χ suffered from sector By the end of y.

[0106] SIR_是如果终端y占用这一资源,则Al中的终端χ受到的来自扇区By中的终端y的干扰。 [0106] SIR_ interference if the terminal y occupy this resource, the Al terminal in χ suffered from sector By the end of y.

[0107] SIRA2By是如果终端y占用这一资源,则A2中的终端χ受到的来自扇区By中的终端y的干扰。 [0107] SIRA2By interference if the terminal y occupy this resource, then the terminal A2 χ suffered from sector By the end of y.

[0108] 如果(资源,终端y)大于预定义值SIRmin,则在具有调度优先级B的扇区中的终端y可以使用已经在具有调度优先级A的一个或者若干扇区中使用的相同帧资源,否则在具有调度优先级B的扇区中的终端y应当避免这一帧资源。 [0108] if (resource, the terminal y) is greater than a predefined value SIRmin, having the scheduling priority in the sector B y can use a terminal having the same frame or a plurality of sector A scheduling priority of use resources otherwise have scheduling priority sector in the terminal B y should avoid this frame resources.

[0109] 反映使发送的数据的质量下降的干扰情形的任何其它量可以取代SIR用于调度用途。 [0109] reflect the amount that any other degradation of the data transmission interference scenarios may be substituted SIR for scheduling purposes. 这样的量可以是CQI (信道质量指标)、上行/下行路径损耗、用于最好和最坏传输条件的预编码矩阵索引(PMI)、...。 Such amount may be a CQI (Channel Quality Indicator), uplink / downlink path loss, a precoding matrix index (PMI) for the best and worst transmission conditions, ....

[0110] 当具有调度优先级B的扇区完成针对帧布局N的计算时,它向具有调度优先级C 的所有它的相邻扇区发送帧布局N。 [0110] when the sector has a scheduling priority B to complete the calculation of N-frame layout for, it sends frame layout to all its neighboring sectors have scheduling priority C of N.

[0111] 在具有调度优先级C的扇区中的调度: [0111] In the sector having scheduling priority scheduling in C:

[0112] 在为将来帧N计算帧布局之前,具有调度优先级C的扇区需要为它的每个需要将来帧N中的资源的终端(由终端编号ζ (终端ζ)代表)计算偏好矩阵。 [0112] In the prior frame N calculation frame future layout, with a scheduling priority sector C needs for each of its needs in the future frame N terminal resources (from the terminal number ζ (terminal ζ) on behalf of) preference matrix calculation . 每个矩阵元素代表在终端ζ将放入帧资源中时,该帧资源的最小S^值。 Each matrix element represents the terminal ζ resources will be placed in a frame, the frame resource smallest S ^ values.

[0113] 为了计算偏好矩阵,具有调度优先级C的扇区需要: [0113] In order to calculate the preference matrix, having scheduling priority sector C needs:

[0114]-来自具有调度优先级A和B的所有相邻扇区的帧N的帧布局 [0114] - N from the frame having a frame layout scheduling priority A and B of all neighboring sectors

[0115]-在具有调度优先级C的扇区中生成的探测表:TBSCz,Cz、TBScz,Ax, TBSte,&(例如在图2 中:TBSczjCz> TBSCZjA0> TBSCZjA1> TBSCZjA2> TBSCZjB0> TBSCZjB1> TBSCZjB2) [0115] - in the sector have scheduling priority C generated in the probe table: TBSCz, Cz, TBScz, Ax, TBSte, & (for example in Figure 2: TBSczjCz> TBSCZjA0> TBSCZjA1> TBSCZjA2> TBSCZjB0> TBSCZjB1> TBSCZjB2 )

[0116]-具有调度优先级A和B的周围扇区向具有调度优先级C的扇区发送的探测表: TBSAs? ΑχΛ TBSBy,By、TBSAs? 0ζΛ TBSBy? Cz (例如在图2中:TBSaq,aq、 TBSau Α1 λ TBSa2? Α2Λ TBSbo? βολ TBSbu Bi、TBSB2?Β2λ TBSao?0ζΛ TBSauCzΛ TBSa2?TBSbo?TBSbi?TBSB2?Cz) [0116] - has detected the scheduling priority sectors around the table A and B to C sector having scheduling priority transmitted:??? TBSAs ΑχΛ TBSBy, By, TBSAs 0ζΛ TBSBy Cz (for example in Figure 2: TBSaq , aq, TBSau Α1 λ TBSa2? Α2Λ TBSbo? βολ TBSbu Bi, TBSB2? Β2λ TBSao? 0ζΛ TBSauCzΛ TBSa2? TBSbo? TBSbi? TBSB2? Cz)

[0117]-用于在具有调度优先级C的扇区中的所有已建立连接的业务参数(例如周期、比特速率、优先级、..)以预测将来帧N中的所需帧资源数量 [0117] - for all service parameters in connection with scheduling priority sector in the C (e.g., period, bit rate, priority, .. ) to predict the future number of frames of N frames required resources

[0118] 具有调度优先级C的扇区计算的偏好矩阵可以是: [01] have scheduling priority sector C preference matrix can be calculated:

[0119] I^refC (资源,终端z) = Min(SIRCzAx, SIRCzBy, SIRAxCz,SIRByCz) [0119] I ^ refC (resources, terminal z) = Min (SIRCzAx, SIRCzBy, SIRAxCz, SIRByCz)

[0120] 由具有调度优先级A和B的扇区包围的具有调度优先级C的扇区计算的偏好矩阵的例子: [0120] with scheduling priority sector by sector C having a scheduling priority A and B surrounded calculated preference matrices Examples:

9[0121] PrefCz (资源,终端z) = Min (SIRCzA。,SIRCzA1, SIRCzA2, SIRCzB0, SIRCzB1, SIRCzB2, SIRaocz, SIRaicz' SIRA2Cz? SIRBOCZ' SIRB1Cz? SIRB2Cz) 9 [0121] PrefCz (resources, terminal z) = Min (SIRCzA., SIRCzA1, SIRCzA2, SIRCzB0, SIRCzB1, SIRCzB2, SIRaocz, SIRaicz 'SIRA2Cz? SIRBOCZ' SIRB1Cz? SIRB2Cz)

[0122] 如果ft~efcz (资源,终端ζ)大于预定义值SIRmin,则在具有调度优先级C的扇区中的终端Z可以使用已经在具有调度优先级A或者B的一个或者若干扇区中使用的相同帧资源,否则在具有调度优先级C的扇区中的终端ζ应当避免这一帧资源。 [0122] If ft ~ efcz (resources, terminal ζ) is greater than the predefined value SIRmin, then having scheduling priority sector in the terminal C Z can use already has one or several scheduling priority A or B sector Resource use the same frame, or having a sector C scheduling priority of the terminal ζ frame should avoid this resource.

[0123] 至此,已经使用在上行中评估的信道具体信息来推断下行中的信道具体信息。 [0123] Thus, the assessment has been used in the uplink channel specific information to deduce the downlink channel specific information. 当上行和下行传输出现于相同频率上时,这在TDD(时分双工系统)中是有效假设。 When the uplink and downlink transmission occurs on the same frequency, which TDD (time division duplex system) in the efficient market hypothesis.

[0124] 在FDD(频率时间双工)系统中,情况并非如此。 [0124] In FDD (frequency-time duplex) system, is not the case. 为了获得用于适当发送方向的可靠信道具体信息,不能使用UL探测信号来执行DL路径损耗的计算而需要使用DL测量来执行该计算,即需要附加测量。 In order to obtain reliable channel specific information for proper transmission direction can not be used to perform calculations UL sounding signal DL path loss and the need to perform the measurements using the DL calculation, i.e., the need for additional measurements.

[0125] 例如,为了计算服务扇区中的DL路径损耗,在服务扇区(例如Ax)中的每个终端测量服务扇区中的BS发送的DL前同步码的接收功率。 [0125] For example, the service sector in order to calculate the DL path loss, the service sector (e.g., Ax) before the DL reception power measured in each terminal in the serving sector BS transmits the preamble. 然后可以针对每一终端例如在TBSAX, Ax中存储这些测量。 These measurements can then be stored, for example in TBSAX, Ax in for each terminal. 其它方法也可以用于这一目的。 Other methods may also be used for this purpose. 例如保留DL帧中的少量帧资源。 For example, a small frame retention DL frame resources. 与在协调探测的情况下相似,仅在协调探测扇区组的一个扇区(例如图1中的扇区Si)中的BS 在这一帧资源中发送DL突发。 In the case of similar coordination detection, detection of only one sector sector coordination group (e.g., FIG. 1 sector Si) in the BS transmits a DL burst in the frame resource. 在扇区SO和所有周围扇区中的所有终端接收DL突发、测量接收信号功率并且将它发送到它的服务BS,该BS将它存储于表中。 All terminals in all sectors SO and surrounding sectors DL burst reception, measuring the received signal power and send it to its serving BS, the BS stores it in the table. 然后,扇区与在TDD情况下相似地交换表。 Then, sector and similar exchange table in the TDD case.

[0126] 在所有扇区已经为帧N生成帧布局之后,每个扇区最晚在帧NI中需要根据它的预先计算的用于帧N的帧布局和当前业务要求将数据调度到帧N中。 [0126] After all sectors have been generated for the frame N frame layout, each sector in the latest frame NI requires pre-calculated based on its current service frame layout and the requirements for the data frame N to frame N scheduler in. 在DL调度的情况下, 需要将那时存在于BS中的数据调度到DL帧中。 In the case of DL scheduling, scheduling data then needs to be present in the BS in the DL frame.

[0127] 在UL调度的情况下,需要为终端中等待的数据生成UL授权。 [0127] In the case of UL scheduling need to generate UL authorization for the terminal waiting for data.
