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, by a first device, whether downlink allocation information has been transmitted from the first device towards a second device in a wireless communication system, wherein the downlink allocation information comprises a downlink allocation table; and

transmitting a message comprising transmittal information and uplink allocation information from the first device towards the second device, wherein the uplink allocation information comprises an uplink allocation table, and wherein the transmittal information indicates whether the downlink allocation information has been transmitted.

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

5. 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.

6. A non-transitory computer readable medium tangibly embodying a computer program executable by a processor to perform operations, said operations comprising:

determining whether downlink allocation information has been transmitted from a first device towards a second device in a wireless communication system, wherein the downlink allocation information comprises a downlink allocation table; and

transmitting a message comprising transmittal information and uplink allocation information from the first device towards the second device, wherein the uplink allocation information comprises an uplink allocation table, and wherein the transmittal information indicates whether the downlink allocation information has been transmitted.

7. A computer readable medium as in claim 6, wherein the transmittal information comprises at least one bit in the uplink allocation table.

8. An apparatus comprising at least one processor;

and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

to determine whether downlink allocation information has been transmitted towards another apparatus, wherein the downlink allocation information comprises a downlink allocation table; and

to transmit a message comprising transmittal information and uplink allocation information towards the other apparatus, wherein the uplink allocation information comprises an uplink allocation table, and wherein the transmittal information indicates whether the downlink allocation information has been transmitted.

9. An apparatus as in claim 8, wherein the uplink allocation information comprises the transmittal information.

10. An apparatus as in claim 8, wherein the transmittal information comprises at least one bit.

11. An apparatus as in claim 8, wherein the transmittal information comprises at least one bit in the uplink allocation table.

12. An apparatus as in claim 8, wherein the transmittal information comprises one bit for each constituent signal of a multiple input/multiple output (MIMO) transmission.

13. An apparatus as in claim 8, wherein the apparatus comprises a base station.

14. A method comprising:

detecting whether a downlink allocation signal, comprising a downlink access table, from a first device is received at a second device on a dedicated resource of a wireless communication system;

detecting whether an uplink allocation signal, comprising an uplink access table, from the first device is received at the second device on a shared resource of the wireless communication system; and

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

15. A method as in claim 14, wherein the at least one allocation comprises an uplink allocation.

16. A method as in claim 15, wherein the uplink allocation table is indicative of the uplink allocation.

17. A method as in claim 14, 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 downlink allocation signal and the detection outcome for the uplink allocation signal, whether the second allocation has failed.

18. A method as in claim 17, wherein the first allocation comprises an uplink allocation and the second allocation comprises a downlink allocation.

19. A method as in claim 18, wherein uplink allocation table is indicative of the uplink allocation and a downlink allocation table is indicative of the downlink allocation.

20. A method as in claim 14, wherein the uplink allocation signal comprises a control signal.

21. The method of claim 14, where, in response to detecting that the downlink allocation signal was not received on the dedicated resource and detecting that the uplink allocation signal was received on the shared resource, a determination is made that an uplink allocation for the first device has failed.

22. The method of claim 14, where, in response to detecting that the downlink allocation signal was not received on the dedicated resource and detecting that the uplink allocation signal was not received on the shared resource, a determination is made that an uplink allocation for the first device has failed and a downlink allocation for the first device has failed.

23. A non-transitory computer readable medium tangibly embodying a computer program executable by a processor to perform operations, said operations comprising:

detecting whether a downlink allocation signal, comprising a downlink access table, from a first device is received at a second device on a dedicated resource of a wireless communication system;

detecting whether an uplink allocation signal, comprising an uplink access table, from the first device is received at the second device on a shared resource of the wireless communication system; and

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

24. A computer readable medium as in claim 23, wherein the at least one allocation comprises an uplink allocation, wherein the uplink allocation table is indicative of the uplink allocation.

25. An apparatus comprising at least one processor;

and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

to detect whether a downlink allocation signal, comprising a downlink access table, from a first device is received by the apparatus on a dedicated resource;

to detect whether an uplink allocation signal, comprising an uplink access table, from the first device is received by the apparatus on a shared resource; and

to determine, based on a detection outcome for the downlink allocation signal and a detection outcome for the uplink allocation signal, whether at least one allocation for the first device has failed.
