Abstract

Apparatus, and an associated method, for providing notification of communication resource allocation to perform an EDGE-based, or other, data radio communication service. A matrix representer forms a matrix representation of communication resource allocations made across a plurality of radio carriers. A bit map constructor constructs a bit map of the matrix representation. And, an RLC header is formed that includes a header extension that is populated with the assignment bit map.

Claims

1. Network apparatus for generating notification of a communication resource allocation allocable across a group of radio carriers and time slots, said apparatus comprising:

a matrix representer configured to represent the communication resources allocated across at least one combination of radio carriers and time slots for communication of representation data in matrix form;

a bit map constructor adapted to receive indication of allocation of a representation of communication resources in the matrix form, allocated for communication of data, said bit map constructor configured selectably to construct a first assignment bit map of values responsive to the indication of the allocation of the communication resources; and

a message generator adapted to receive the first assignment bit map, said message generator configured to generate an RLC block having a header extension field populated with values of the first assignment bit map.

2. The apparatus of claim 1 wherein the RLC block generated by said message generator comprises a header part of which the header extension field forms a portion.

3. The apparatus of claim 2 wherein the RLC block further comprises a RLC (Radio Link Control) layer message.

4. The apparatus of claim 2 wherein the RLC block further comprises a RLC (Radio Link Control) data block.

5. The apparatus of claim 2 wherein the RLC block further comprises a payload, the payload including data for communication.

6. The apparatus of claim 5 wherein the RLC block further provides an indication when the RLC block contains the header extension field.

7. The apparatus of claim 2 wherein the header extension field generated by said message generator comprises part of a Radio Link Control, RLC, header.

8. The apparatus of claim 7 wherein the RLC header further includes an indication of a value to indicate whether the header extension field is populated with the values of the first assignment bit map.

9. The apparatus of claim 1 further comprising a detector adapted to receive an indication of a communication-station communication capability and wherein the indication of the allocation of the communication resources of which said bit map constructor is adapted to receive, is of values determined responsive, in part, to the communication-station communication capability.

10. The apparatus of claim 9 wherein the indication of the communication-station communication capability comprises a mobile station classmark.

11. The apparatus of claim 1 wherein the values populating the header extension field generated by said message generator defines assignment allocation of the communication resources for a selected time period.

12. The apparatus of claim 11 wherein the selected time period comprises a subsequent block period.

13. Apparatus for a mobile station operable pursuant to communication of data configured into at least a first data block across at least one combination of radio carriers and time slots to perform a radio communication service, said apparatus comprising:

a detector configured to detect, once delivered to the mobile station, a first portion of an RLC block that includes an indication of whether the RLC block includes a communication resource assignment and configured to detect a second portion, of the RLC block, which forms a header extension field populated with values including a first assignment bit map formed from a matrix-form representation of allocation of communication resources across the at least one combination of radio carriers and time slots pursuant to the radio communication service; and

a controller adapted to receive an indication of detection made by said detector, said controller configured to control operation of the mobile communication station responsive to the first assignment bit map of the second portion of RLC block and that identifies the assignment allocation of the communication resources across the at least one combination of radio carriers and time slots, if the first portion of the RLC block includes an indication that the RLC block includes a communication resource assignment.

14. The apparatus of claim 13 further comprising a communication capability indicia generator configured to generate one or more communication capability indicia, the message detected by said detector of values responsive, in part, to an earlier generated communication capability indicia.

15. A method for generating notification at a network station that operates pursuant to a data radio communication service in which communication resources are allocated of a communication resource assignment allocation across at least one combination of radio carriers and time slots to perform a radio communication service, said method comprising the operations of:

representing the communication resources allocated across the at least one combination of radio carriers and time slots for the communication of the data in matrix form;

constructing a first assignment bit map, responsive to the representation of the communication resources allocated in the matrix form, and an assignment allocation of the communication resources across the at least one combination of radio carriers and time slots to perform the radio communication service; and

generating a header extension field that identifies the assignment allocation of the communication resources across the at least one combination of radio carriers and time slots, the header extension field formed of a first portion including an indication whether the message includes a communication resource assignment and, if so, of a second portion including the values of the first assignment bit map.

16. The method of claim 15 further comprising the operations of:

sending the header extension field, as a portion of an RLC Block, generated during said operation of generating to a remote station; and

detecting the header extension field portion of the RLC block, once delivered to the remote station.

17. The method of claim 16 further comprising the operation of controlling operation of the remote station responsive to the values of the first assignment bit map when included in the second portion of the header extension field.

18. The method of claim 15 further comprising the initial operation of receiving a communication station capability indicia and wherein the allocation of the communication resources of which the first assignment bit map is representative is, in part, responsive to the communication station capability indicia.

19. The method of claim 15 wherein the header extension field generated during said operation of generating comprises a Radio Link Control, RLC, data block, and wherein the first portion and the second portion form at least a portion of a header part of the RLC data block.

20. The method of claim 19 wherein the second portion comprises a header part extension of the RLC data block.
