Abstract

In one exemplary embodiment of the invention, a method including: determining whether first allocation information has been transmitted from a first device towards a second device in a wireless communication system; and transmitting a message including transmittal information and second allocation information from the first device towards the second device, wherein the transmittal information corresponds to the determined transmittal of the first allocation information. In another exemplary embodiment of the invention, a method including: detecting whether a first signal is received on a dedicated resource of a wireless communication system; detecting whether a second signal is received on a shared resource of the wireless communication system; and determining, based on a detection outcome for the first signal and a detection outcome for the second signal, whether at least one allocation has failed.

Claims

1. A method comprising:

determining whether first allocation information has been transmitted from a first device towards a second device in a wireless communication system; and

transmitting a message comprising transmittal information and second allocation information from the first device towards the second device, wherein the transmittal information corresponds to the determined transmittal of the first allocation information.

2. A method as in claim 1, wherein the second allocation information comprises the transmittal information.

3. A method as in claim 1, wherein the transmittal information comprises at least one bit.

4. A method as in claim 1, wherein the second allocation information comprises uplink allocation information.

5. A method as in claim 4, wherein the uplink allocation information comprises an uplink allocation table.

6. A method as in claim 5, wherein the transmittal information comprises at least one bit in the uplink allocation table.

7. A method as in claim 1, wherein the first allocation information comprises downlink allocation information.

8. A method as in claim 7, wherein the downlink allocation information comprises a downlink allocation table.

9. A method as in claim 1, wherein the transmittal information comprises one bit for each constituent signal of a multiple input/multiple output (MIMO) transmission.

10. A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, said operations comprising:

determining whether first allocation information has been transmitted from a first device towards a second device in a wireless communication system; and

transmitting a message comprising transmittal information and second allocation information from the first device towards the second device, wherein the transmittal information corresponds to the determined transmittal of the first allocation information.

11. A program storage device as in claim 10, wherein the second allocation information comprises uplink allocation information, wherein the uplink allocation information comprises an uplink allocation table, wherein the transmittal information comprises at least one bit in the uplink allocation table.

12. An apparatus comprising:

a data processor configured to determine whether first allocation information has been transmitted towards another apparatus; and

a transmitter configured to transmit a message comprising transmittal information and second allocation information towards the other apparatus, wherein the transmittal information corresponds to the determined transmittal of the first allocation information.

13. An apparatus as in claim 12, wherein the second allocation information comprises the transmittal information.

14. An apparatus as in claim 12, wherein the transmittal information comprises at least one bit.

15. An apparatus as in claim 12, wherein the second allocation information comprises uplink allocation information and wherein the uplink allocation information comprises an uplink allocation table.

16. An apparatus as in claim 15, wherein the transmittal information comprises at least one bit in the uplink allocation table.

17. An apparatus as in claim 12, wherein the first allocation information comprises downlink allocation information and wherein the downlink allocation information comprises a downlink allocation table.

18. An apparatus as in claim 12, wherein the transmittal information comprises one bit for each constituent signal of a multiple input/multiple output (MIMO) transmission.

19. An apparatus as in claim 12, wherein the apparatus comprises a base station.

20. A method comprising:

detecting whether a first signal is received on a dedicated resource of a wireless communication system;

detecting whether a second signal is received on a shared resource of the wireless communication system; and

determining, based on a detection outcome for the first signal and a detection outcome for the second signal, whether at least one allocation has failed.

21. A method as in claim 20, wherein the at least one allocation comprises an uplink allocation.

22. A method as in claim 21, wherein an uplink allocation table is indicative of the uplink allocation.

23. A method as in claim 20, wherein the at least one allocation comprises a first allocation and a second allocation, the method further comprising:

determining, based on the detection outcome for the first signal and the detection outcome for the second signal, whether the second allocation has failed.

24. A method as in claim 23, wherein the first allocation comprises an uplink allocation and the second allocation comprises a downlink allocation.

25. A method as in claim 24, wherein an uplink allocation table is indicative of the uplink allocation and a downlink allocation table is indicative of the downlink allocation.

26. A method as in claim 20, wherein the second signal comprises a control signal.

27. A program storage device, readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, said operations comprising:

detecting whether a first signal is received on a dedicated resource of a wireless communication system;

detecting whether a second signal is received on a shared resource of the wireless communication system; and

determining, based on a detection outcome for the first signal and a detection outcome for the second signal, whether at least one allocation has failed.

28. A program storage device as in claim 27, wherein the at least one allocation comprises an uplink allocation, wherein an uplink allocation table is indicative of the uplink allocation.

29. An apparatus comprising:

a first receiver;

a first detector configured to detect whether a first signal is received by the first receiver on a dedicated resource;

a second receiver;

a second detector configured to detect whether a second control signal is received by the second receiver on a shared resource; and

a data processor configured to determine, based on a detection outcome for the first signal and a detection outcome for the second control signal, whether at least one allocation has failed.

30. An apparatus as in claim 29, wherein the at least one allocation comprises an uplink allocation.

31. An apparatus as in claim 29, wherein the at least one allocation comprises a first allocation and a second allocation, wherein the data processor is further configured to determine, based on the detection outcome for the first signal and the detection outcome for the second signal, whether the second allocation has failed.

32. An apparatus as in claim 31, wherein the first allocation comprises an uplink allocation and the second allocation comprises a downlink allocation.
