Abstract

A method, user equipment, network device, and software product enable allocation of a number of resource blocks over a downlink to the user equipment. The resource blocks are grouped into a number of groups of the blocks, the number of groups being no greater than a maximum number. The resource blocks are arranged in an adjacent manner within each of the groups. The resource blocks are allocated by operating on the groups, and the allocation is signalled using a group allocation indication.

Claims (40)

1. A method comprising:
grouping resource blocks into a number of groups of the blocks, said number of groups being no greater than a maximum number, and said blocks arranged adjacently in each of said groups;
allocating the resource blocks by operating on the groups; and signaling the allocation using a group allocation indication.
2. The method of claim 1, wherein said group allocation indication has a number of bits equal to said maximum number of groups.
3. The method of claim 1, wherein said maximum number of groups depends at least upon a system bandwidth.
4. The method of claim 3, wherein a size of at least one of said groups depends at least upon said maximum number of groups.
5. The method of claim 1, wherein a size of at least one of said groups depends at least upon a system bandwidth.
6. The method of claim 1, wherein the allocation is accomplished by transmitting a number of bits substantially equal to the maximum number of groups to a user equipment in separate coding instead of joint coding.
7. The method of claim 1, wherein the groups are allocated in an unrestricted instead of adjacent manner.
8. The method of claim 1, wherein the operating on the groups operates on the maximum number of the groups.
9. The method of claim 1, wherein the grouping is performed dynamically instead of semi-statically.
10. The method of claim 1, wherein the allocation is a downlink allocation that includes separate entries for downlink and uplink resource assignments.
11. An apparatus comprising:
means for grouping resource blocks into a number of groups of the blocks, said number of groups being no greater than a maximum number, and said blocks arranged adjacently in each of said groups;
means for allocating the resource blocks by operating on the groups; and means for signaling the allocation using a group allocation indication.
12. The apparatus of claim 11, wherein said group allocation indication has a number of bits equal to said maximum number of groups.
13. The method of claim 11, wherein said maximum number of groups depends at least upon a system bandwidth.
14. The method of claim 13, wherein a size of at least one of said groups depends at least upon said maximum number of groups.
15. The apparatus of claim 11, wherein the means for signaling the allocation signals a number of bits substantially equal to the maximum number of groups to a user equipment in separate coding instead of joint coding.
16. The apparatus of claim 11, wherein the means for allocating the resource blocks allocates the groups in an unrestricted instead of adjacent manner.
17. The apparatus of claim 11, wherein the means for allocating the resource blocks operates on the maximum number of the groups.
18. The apparatus of claim 11, wherein the means for grouping functions dynamically instead of semi-statically.
19. The apparatus of claim 11, wherein the means for allocating yields a downlink allocation that includes separate entries for downlink and uplink resource assignments.
20. The apparatus of claim 11, wherein said apparatus is a network element.
21. A software product, the software product comprising a computer readable medium having executable codes embedded therein; the codes, when executed, adapted to carry out the functions of:
grouping resource blocks into a number of groups of the blocks, said number of groups being no greater than a maximum number, and said blocks arranged adjacently in each of said groups;
allocating the resource blocks by operating on the groups; and signaling the allocation using a group allocation indication.
22. The software product of claim 21, wherein said group allocation indication has a number of bits equal to said maximum number of groups.
23. The software product of claim 21, wherein said maximum number of groups depends at least upon a system bandwidth.
24. The software product of claim 23, wherein a size of at least one of said groups depends at least upon said maximum number of groups.
25. The software product of claim 21, wherein the allocation is accomplished by transmitting a number of bits substantially equal to the maximum number of groups to a user equipment in separate coding instead of joint coding.
26. The software product of claim 21, wherein the groups are allocated in an unrestricted instead of adjacent manner.
27. A apparatus comprising:
an aggregation module configured to group resource blocks into a number of groups of the blocks, said number of groups being no greater than a maximum number, and said blocks arranged adjacently in each of said groups;
an allocation module configured to allocate the resource blocks by operating on the groups; and a signaling module configured to signal the allocation using a group allocation indication.
28. The apparatus of claim 27, wherein said group allocation indication has a number of bits equal to said maximum number of groups.
29. The apparatus of claim 27, wherein said maximum number of groups depends at least upon a system bandwidth.
30. The apparatus of claim 29, wherein a size of at least one of said groups depends at least upon said maximum number of groups.
31. The apparatus of claim 27, wherein the signaling module is further configured to signal a number of bits equal to the maximum number of groups to a user equipment in separate coding instead of joint coding.
32. The apparatus of claim 27, wherein the allocation module is configured to allocate the groups in an unrestricted instead of adjacent manner.
33. The apparatus of claim 27, wherein said apparatus is a network element.
34. An apparatus comprising:

a transceiver configured to receive an allocation of a number of resource blocks over a downlink; and a processor configured to determine the allocation from a group allocation indication;
wherein the allocation indication discloses resource blocks arranged in an adjacent manner within each of a plurality of groups, said number of groups being no greater than a maximum number.
35. The apparatus of claim 34, wherein said group allocation indication has a number of bits equal to said maximum number of groups.
36. The apparatus of claim 34, wherein said maximum number of groups depends at least upon a system bandwidth.
37. The apparatus of claim 36, wherein a size of at least one of said groups depends at least upon said maximum number of groups.
38. The apparatus of claim 34, wherein the group allocation indication includes a number of bits substantially equal to the maximum number of groups, in separate coding instead of joint coding.
39. The apparatus of claim 34, wherein the allocation of the groups is unrestricted instead of adjacent.
40. The apparatus of claim 34, wherein said apparatus is a user equipment.
