Abstract

A wireless communication infrastructure entity assigns a plurality of schedulable wireless communication entities to a group wherein each entity is assigned a location within the group. The infrastructure entity indicates which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource, for example in a first bitmap (510), and indicates radio resource allocation policy information (520) and indicates a weighting for each assigned wireless communication entity, for example, in a second bitmap (530), to the schedulable wireless communication entities that have been assigned a radio resource.

Claims

1. A wireless communication infrastructure entity comprising:

a transceiver;

a processor coupled to the transceiver,

the processor configured to assign a plurality of schedulable wireless communication entities to a group, each schedulable wireless communication entity assigned a position within a bit map associated with the group;

the processor configured to indicate which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource based on values in the assigned positions of the bitmap;

the processor configured to indicate radio resource allocation policy information to the schedulable wireless communication entities that have been assigned a radio resource, the radio resource allocation policy information specifying how the assigned radio resources are distributed among the schedulable wireless communication entities to which the radio resources have been assigned.

2. The entity of claim 1,

the processor configured to assign the group a shared time frequency resource,

the processor configured to indicate to the plurality of schedulable wireless communication entities assigned to the group which of the schedulable wireless communication entities have been assigned radio resources of the shared time frequency resource.

3. The entity of claim 1, the radio resource allocation policy information indicating that the radio resources assigned to the schedulable wireless communication entities are of the same size.

4. The entity of claim 1, the radio resource allocation policy information indicating that the assigned radio resources are distributed equally among the schedulable wireless communication entities to which the radio resources have been assigned.

5. The entity of claim 1, the radio resource allocation policy information indicating that a number of radio resources assigned to the schedulable wireless communication entities is specified in an allocation bitmap.

6. The entity of claim 1, the radio resource allocation policy information indicating that a weighting for dividing the radio resources assigned to the schedulable wireless communication entities is specified in an allocation bitmap.

7. A wireless communication network infrastructure entity comprising:

a transceiver;

a processor coupled to the transceiver,

the processor configured to assign a plurality of schedulable wireless communication entities to a group, each schedulable wireless communication entity assigned a position within a bit map associated with the group;

the processor configured to indicate which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource based on values in the assigned positions of the bitmap;

the processor configured to indicate radio resource assignment weighting information to the schedulable wireless communication entities to which radio resources have been assigned.

8. The entity of claim 7, the processor configured to indicate the radio resource assignment weighting information by indicating a proportion of radio resources assigned to each of the schedulable wireless communication entities to which radio resources have been assigned.

9. The entity of claim 7, the processor configured to indicate the radio resource assignment weighting information by indicating a number of radio resources assigned to each schedulable wireless communication entity to which radio resources have been assigned.

10. The entity of claim 7, the processor configured to indicate the radio resource assignment weighting information in a bitmap, the bitmap includes a bitmap location for each schedulable wireless communication entity to which radio resources have been assigned, the bitmap does not include a bitmap location for schedulable wireless communication entities to which radio resources have not been assigned.

11. The entity according to claim 10, wherein the bitmap has more than one bit for each location.

12. The entity according to claim 7, the processor configured to indicate the radio resource assignment weighting information by indicating modulation and coding information.

13. The entity method according to claim 7, wherein each unique weighting indication further indicates one or more vocoder frame formats.

14. A schedulable wireless communication entity assigned to a group with a plurality of other schedulable wireless communication entities wherein each schedulable wireless communication entity is assigned a position within a bit map associated with the group and wherein the group is assigned a shared radio resource, the entity comprising:

a transceiver;

a processor coupled to the transceiver,

the entity configured to receive an indication that the entity has been assigned a radio resource, the indication is based on a value of the assigned position within the bitmap;

the entity configured to receive radio resource allocation policy information indicating how the shared radio resources are distributed among the schedulable wireless communication entities to which the radio resources have been assigned.

15. The entity of claim 14, the entity configured to receive the indication that the schedulable wireless communication entity has been assigned a radio resource in a first bitmap wherein each schedulable wireless communication entity of the group corresponds to a location within the bitmap.

16. The entity of claim 14, the entity configured to receive radio resource assignment weighting information in a second bitmap, wherein each schedulable wireless communication entity to which radio resources have been assigned has a location within the second bitmap and wherein schedulable wireless communication entities to which radio resources have not been assigned do not have a location in the second bitmap.

17. The entity of claim 14, the entity configured to use the radio resource allocation policy information to determine whether the radio resources assigned to the schedulable wireless communication entities are of the same size.

18. The entity of claim 14, the entity configured to use the radio resource allocation policy information to determine whether the assigned radio resources are distributed equally among the schedulable wireless communication entities to which the radio resources have been assigned.

19. The entity of claim 14, the entity configured to use the radio resource allocation policy information to determine that a number of radio resources assigned to the schedulable wireless communication entities is specified in a second bitmap.

20. The entity of claim 14, the entity configured to use the radio resource allocation policy information to determine that weighting information for dividing the radio resources assigned to the schedulable wireless communication entities is specified in a second bitmap.

21. A wireless communication scheduling entity comprising:

a transceiver;

a processor coupled to the transceiver,

the processor configured to assign a plurality of schedulable wireless communication entities to a group to which a shared time frequency resource is assigned,

each schedulable wireless communication entity assigned a position within a bit map associated with the group;

the processor configured to assign a repeating sequence of frames to the group,

each of the plurality of schedulable wireless communication entities assigned a frame within the repeating sequence in which its first transmission in a series of hybrid automatic repeat request transmissions will occur using the shared time frequency resource.

22. The entity of claim 21, the processor configured to send an indication of when the first transmission will occur relative to a known boundary.
