Abstract

这里公开了一种允许用户设备(UE)使用设备到设备(D2D)模式来直接与其他用户设备发送信息的装置和方法。希望在D2D模式中传送至第二D2D UE(dUE2)的第一D2D UE(dUE1)对演进的节点B(eNB)作出各种通信请求，演进的节点B可促进dUE1和dUE2之间的连接。在这些请求中的是经由WiFi而不是经由长期演进(LTE)来作出D2D连接。eNB确定dUE1和dUE2的WiFi能力，然后分配要被dUE1扫描的可用信道子集以及要被dUE2扫描的分开的可用信道子集。然后，eNB可以基于dUE1和dUE2所执行的扫描来分配WiFi信道。

背景技术
用户设备(UE)已变得日益常见，用户设备包括诸如电话、平板电脑、电子书阅读器、膝上型计算机等移动设备。伴随着这种设备的使用的增长，基于邻近度的应用和服务的使用也增长。基于邻近度的应用和服务是基于这样的认知：两个或更多个设备/用户彼此接近并且希望彼此通信。示例性的基于邻近度的应用和服务包括社交联网、移动电子商务、广告、游戏等。在当前的技术中，这种应用和服务使用传统的移动宽带网络。对于网络和UE两者而言，这种移动宽带网络可能不会导致最佳性能。
附图说明
图1是本发明一实施例的说明概述。
图2是一实施例的另一概述。
图3是示出一实施例的操作的流程图。
具体实施方式
以下描述和附图充分说明了多个具体实施例，以使本领域的技术人员能实践它们。其它实施例可以结合结构的、逻辑的、电子的过程及其他变化。多个实例仅仅代表可能的变化。除非明确需要，个体组件和功能是任选的，操作的顺序可以变化。一些实施例的部分和特征可以被包括在其它实施例的部分和特征中，或者替代其它实施例的部分和特征。权利要求书中提出的实施例包含那些权利要求的所有可能等价物。
在以下详细描述中，提出了许多具体细节以便提供本发明的透彻理解。然而，本领域的技术人员将理解，可以无需这些具体细节而实现本发明。在其它实例中，未详细描述公知的方法、过程、组件和电路以便不混淆本发明。
尽管本发明的实施例不限于此，但是这里使用的术语“多”和“多个”可以包括例如“多个”或“两个或更多个”。术语“多”和“多个”可以在整个说明书中用来描述两个或更多个组件、设备、元件、单元、参数等等。例如，“多个站”可以包括两个或更多个站。
第三代合伙人计划(3GPP)是在1998年12月建立的将多个电信标准机构(称为组织伙伴)汇集到一起的合作协议，多个电信标准机构目前包括无线电工业与商业协会(ARIB)、中国通信标准协会(CCSA)、欧洲电信标准协会(ETSI)、电信行业解决方案联盟(ATIS)、电信技术协会(TTA)和电信技术委员会(TTC)。3GPP的建立在1998年12月通过签署“第三代合伙人计划协议”而生效。
3GPP基于它们支持的演进GSM核心网络和无线电接入技术(用于频分双工(FDD)和时分双工(TDD)两种模式的通用地面无线电接入(UTRA))提供了全局可应用的标准作为第三代移动系统的技术规范和技术报告。3GPP还提供用于维护和开发全球移动通信系统(GSM)的标准作为包括演进无线电接入技术(例如通用分组无线电业务(GPRS)和增强型GSM演进数据速率(EDGE))技术规范和技术报告。与移动电话有关的当前标准的技术规范一般可用于来自3GPP组织的公众。
3GPP目前正在研究3G移动系统的演进，并且考虑针对UTRA网络(UTRAN)的演进的贡献(观点和提议)。3GPP研究会标识了一组高级要求，包括：减少的每比特成本；增加的业务供应(即，以较低成本较高质量供应更多业务)；现有频带和新频带的使用灵活性；具有开放式接口的简化体系结构；以及减少的/合理的终端功耗。2004年12月开始研究UTRA&UTRAN长期演进(UTRAN-LTE，也称为3GPP-LTE和E-UTRA)，目的在于开发一种框架，用于使3GPP无线电接入技术演进为高数据速率、低等待时间和分组优化的无线电接入技术。该研究考虑了对无线电接口物理层(下行链路和上行链路)的修改(诸如支持高达20MHz的灵活传输带宽的手段)、新传输方案的引入以及高级多天线技术。3GPP-LTE基于结合正交频分复用(OFDM)技术的无线电接口。OFDM是使用大量紧密间隔的正交子载波来携带相应用户数据信道的数字多载波调制格式。在与射频(RF)传输速率相比(相对)低的码元速率下，每个子载波用一个常规的调制方案来调制，诸如正交幅度调制。实践中，OFDM信号使用快速傅立叶变换(FFT)算法来生成。
在使用基于邻近度的应用的示例性情况下，移动设备或用户设备(UE1)的用户变得物理上接近于另一移动设备UE2。用户可能希望自UE1向UE2传输文件、玩游戏或以其他方式通信。UE1和UE2之间的连接可由应用自动发起，而不是由用户发起。在传统的通信网络中，这一通信通常通过中央协调器而发生，诸如基收发机站、节点B或演进的节点B(eNodeB或eNB)。
然而，存在几个使基于邻近度的通信不同的因素。例如，多个设备间的距离通常小，通信可以是应用驱动的而不是用户发起的(例如，当运行同一应用的第二设备位于邻近时自动通信的应用)。这种基于邻近度的通信有几个方面可以被优化。
图1示出将设备到设备(“D2D”)网络与无线接入网络相组合的系统，无线接入网络诸如长期演进(LTE)网络。移动宽带网络100包括中央协调器，这里示出为eNB102。用户设备(UE)104和106经由LTE通信信道108与eNB 102通信。
图1中还示出D2D群集110、120、130、140和150。D2D群集110、120、130、140和150的每一个包括能够直接彼此通信而无须通过eNB 102通信的多个UE。该应用将具有D2D能力的UE表示为dUE，来说明具有D2D能力的用户设备。在图1中，示出D2D群集的几种不同布局。应当理解，D2D群集的其它配置也是可能的。还应当理解，单个eNB可以支持比图1所示更多的D2D群集。
微微eNB 112耦接至eNB 102。D2D群集110和120耦接至微微eNB112。D2D群集110内是D2D协调器115以及dUE 116和117。D2D协调器115用于管理dUE 116/117和微微eNB 112之间的通信。D2D群集120内是D2D协调器125以及dUE 126和127。UE 122也耦接至微微eNB 112。UE 122不耦接至D2D群集110或120。UE 122可能有或可能没有D2D能力。
dUE 116和117彼此间具有D2D连接，其中dUE 116和dUE 117之间的通信不需要涉及微微eNB 112或eNB 102。相反，信息直接在dUE 116和dUE 117之间传送。该设置提供了多种好处。例如，由于dUE 116和dUE117彼此紧密邻近，因此它们不需要将数据一直传送至eNB 102――因此，一个或两个设备可以使用低功率收发机模式，延长了dUE 116和dUE 117的电池寿命。此外，由于eNB 112和eNB 102未涉及在dUE 116和dUE 117之间的传输中，因此不使用eNB 102和微微eNB 112的有限带宽能力。如果dUE 116或dUE 117需要传送至eNB 102或微微eNB 112，则这一通信通过D2D协调器115而发生。尽管图1示出涉及D2D协调器使用的几种场景，然而应当理解，可以无须任何D2D协调器、而直接在eNB的控制下执行多个设备间的通信，eNB诸如eNB 102或微微eNB 112。类似配置存在于D2D群集120中、在dUE 126和dUE 127之间，但除了D2D群集120中没有D2D协调器。应当理解，在D2D协调器115以及dUE 116和117之间存在连接，它仅仅自图1省略。
D2D群集130包括D2D协调器135、dUE 136和dUE 137。在D2D群集130中，dUE 136和137可以彼此间以及与D2D控制器135直接通信。D2D协调器135用于控制dUE 136和dUE 137之间的D2D连接。D2D 135也可以组织与dUE 136或dUE 137的多播/广播传输。如上所述，dUE 136和137以及D2D协调器135通过使用与单个传统UE相同的空间，释放了eNB 102的带宽。不像D2D群集110和120，没有微微eNB耦接至D2D群集130。
D2D群集140包括微微eNB 141、dUE 142和143；D2D控制器145；以及dUE 146和147。dUE 142和143耦接至微微eNB 141，但不耦接至任何其它UE。D2D协调器145也耦接至微微eNB 142。dUE 146和147处于多跳配置中――仅dUE 146耦接至D2D控制器145。如果微微eNB想要将数据发送至dUE 146，它可以通过D2D协调器/控制器dUE 145发送数据。如果D2D控制器需要将信号发送至dUE 147，信号首先被发送至dUE 146。
D2D群集150包括以网格配置彼此耦接的dUE 152、154、156和158，dUE 152、154、156和158的每一个都如图所示彼此耦接。如果dUE需要将数据发送至它不直接耦接的dUE(例如，dUE 152和156)，则它可以通过所连接的dUE(例如，dUE 154)来发送数据。对于图1所示的所有连接而言，D2D控制器并非必要。
对于每个独立操作的D2D群集110、120、130、140和150，eNB 102不需要处理那么多的话务，从而使eNB 102能服务比本来可能服务的更多的UE以及/或者向其它UE提供较高的吞吐量。然而，存在多个D2D群集会导致小区间干扰的增加。
D2D通信在已许可和未许可的频带内都是可能的。例如，可以经由LTE信号完成dUE1和dUE2之间的D2D通信。在这一情况下，dUE1和dUE2会为D2D通信使用与它们为经由eNB的LTE通信所使用的频率和传输方案相同的频率和传输方案。在称为卸载的过程中，dUE1和dUE2之间的D2D通信也可以经由WiFi信号来完成。在卸载情况下，可以例如经由WiFi信号来执行D2D通信，导致几种好处。
例如，因为WiFi信号处于不同频率下，因此可能与其它LTE信号有较少的干扰。此外，更多带宽可能可用于WiFi频带内的数据传输，使得可以为短距D2D通信实现较高的数据传输速率。WiFi中采用的基于竞争的信道接入机制适合于在本地区域中容纳多个D2D传输。而且，如今WiFi已成为移动设备上的非常常见的组件，使得较易于在卸载方案上实现。
WiFi信号可以处在多种不同的频带中。目前正在使用的三个不同频率范围集中在2.4GHz、5.2GHz和5.8GHz附近(应当注意，有时5.2GHz和5.8GHz频带统称为5GHz频带)。将来可以使用其它频率，诸如3.6GHz和60GHz。为使一个dUE能与另一dUE通信，必须确定这两个设备的能力。例如，一些设备仅能在特定的频率范围下发送。此外，必须确定是否有所有dUE都能在其上工作任何清洁(即，未使用)信道。寻找清洁信道的一种方法是实施完整信道扫描。然而，完整信道扫描可花费几秒钟，这会对具有服务质量(QoS)要求的蜂窝D2D通信造成问题。此外，完整功率扫描可以使用比所需的功率更多的功率，这会有害地损害电池寿命。在那些情况下，几秒的延迟会是不可接受的。会希望缩短执行扫描所需的时间并节省功耗。
除了WiFi之外，D2D通信可以使用其它免许可频带，诸如蓝牙、Zigbee以及修改的LTE技术。由于每个dUE可能不支持所有技术，因此在使用那些频带建立连接之前，需要标识公共技术组和公共工作频带组。
可用于缩短执行扫描所需时间的一种方法是：使用会参与D2D通信的设备来与信道扫描结合。eNB可以标识用于D2D设备的公共技术和频带组。这可以包括自每个设备请求能力报告并且查找公共能力组。此后，eNB可以分割该公共能力组，并且要求每个dUE来扫描公共组的一部分以进行干扰测量。
参照图2，呈现了图1的示意图的简化版本。所示eNB 202耦接至两个UE：dUE1 204和dUE2 206。在dUE1 204和dUE2 206之间建立D2D连接之前，eNB 202可以要求dUE1 204和dUE2 206测量所有可用的WiFi信道。
例如，dUE1和dUE2可能均能在2.4GHz WiFi频带内通信。在北美，2.4GHz WiFi频带具有11个可用信道(在其他国家有更多可用信道)。eNB202可以要求dUE1 204测量信道1到6中存在的干扰，并且要求dUE2测量信道7到11中存在的干扰。在dUE1和dUE2之间分配信道扫描缩短了实施信道扫描所需的时间，并且降低了用于实施功率扫描的功率。之后，dUE1 204和dUE2 206将结果发送至eNB 202，eNB 202然后可以为dUE1204和dUE2206确定用于D2D通信的最佳信道。
参照图3，呈现了详细示出一实施例的操作的流程图。dUE1将RRC消息或其他控制消息发送至eNB，详细表明dUE1的D2D能力(302)。D2D能力可以包括：1)所支持的D2D技术，例如LTE D2D、WiFi D2D等等；以及2)频带、PHY参数、所支持的无线电技术、服务质量(QoS)参数、功率容量等等，使得eNB或D2D设备可以为D2D通信选择适当的技术。在D2D连接建立期间，eNB可以帮助从报告自D2D设备的一组所支持的技术和参数中作出选择，或者eNB可以选择用于多个D2D设备的公共技术和参数组并且使D2D设备作出选择。
eNB存储dUE1的D2D能力(304)。当dUE2连接至eNB时，dUE2将RRC消息或其他控制消息发送至eNB，详细表明dUE2的D2D能力，eNB随后存储dUE2的D2D能力(306)。dUE1和dUE2将消息发送至eNB的这些过程可以是每当UE连接至eNB时要执行的标准协议的一部分。
此后，如果dUE1和dUE2希望在D2D模式中连接，eNB从存储器中检索dUE1和dUE2两者的能力。eNB要求dUE1和dUE2开始WiFi测量过程(308)。如上所述，要求dUE1和dUE2中的每一个仅测量可用WiFi信道的一部分。从302和306确定WiFi信道通常可用于dUE1和dUE2两者。WiFi信道被分割成两个子集。例如，如果信道1到11在2.4GHz频带内可用，则要求dUE1测量信道1到6而同时要求dUE2测量信道7到11。应当理解，每个dUE所测量的部分的交换不受限制。然后，dUE1和dUE2将结果发送至eNB(310)。基于信道质量和干扰状态，eNB选择适当的WiFi信道来用于dUE1和dUE2之间的D2D连接(312)。这可以基于各种标准，诸如信号强度、干扰等。例如，可以经由接收到的信号强度级别和/或占用(其他设备对信道的使用)百分比来评估干扰强度。
然后，eNB将与所选择的WiFi信道有关的信息发送至dUE1和dUE2(314)。然后，dUE1和dUE2继续经由所选WiFi信道进行连接所需的握手过程(316)。dUE1和dUE2之间的握手可以以对于WiFi握手典型的方式发生。
应当理解，在一实施例中可以使用多于两个dUE。例如，可以使用三个dUE，其中dUE1测量信道1到4，dUE2测量信道5到8，dUE3测量信道9到11。应当进一步理解，实施例不限于WiFi的2.4GHz频带。如果dUE能够既使用WiFi的2.4GHz频带又使用其他频带，诸如5.2GHz频带或5.8GHz频带，则两个频带内的信道都可由dUE来测量。例如，dUE1可以测量2.4GHz频带内的信道，而dUE2可以测量5GHz频带内的信道。此后，结果由eNB比较，eNB于是可确定哪个信道应当用于D2D通信。
