Abstract

Method and apparatus are provided to allocate a time and frequency resource of a resource request indicator (RRI) and to transmit an RRI. Codes are allocated for an RRI and other (such as non-RRI) uplink control signaling. The RRI and other uplink control signaling can be multiplexed in the same time and frequency resource, such as through multiplexing in a code division manner.

First claim

What is claimed is:

1. An apparatus, comprising:
a storage medium including executable instructions; and
a processor;
wherein the executable instructions, when executed by the processor, cause the apparatus to:
obtain a code set that is allocated for a resource request indicator (RRI), wherein the RRI comprises a first part and a second part, and the code set comprises a first code allocated for the first part of the RRI, a second code allocated for the first part of the RRI, a third code allocated for the second part of the RRI and a fourth code allocated for the second part of the RRI, each of the foregoing first through fourth codes of the code set being allocated to a user terminal for a time slot; and
extend the RRI using the code set, wherein
in a time domain, an extended manner corresponding to the first code of the code set is identical to an extended manner corresponding to a first code allocated for a pilot part of non-RRI uplink control signaling in the time slot;
in a frequency domain, an extended manner corresponding to the second code of the code set is identical to an extended manner corresponding to a second code allocated for the pilot part of the non-RRI uplink control signaling in the time slot;
in the time domain, an extended manner corresponding to the third code of the code set is identical to an extended manner corresponding to a third code allocated for a data part of the non-RRI uplink control signaling in the time slot;
in the frequency domain, an extended manner corresponding to the fourth code of the code set is identical to an extended manner corresponding to a fourth code allocated for the data part of the non-RRI uplink control signaling in the time slot.

2. The apparatus of claim 1 , wherein
at least one of the first code and the second code of the code set is orthogonal to the corresponding codes allocated for the pilot part of the non-RRI uplink control signaling, and
at least one of the third code and the fourth code of the code set is orthogonal to the corresponding codes allocated for the data part of the non-RRI uplink control signaling.

3. The apparatus of claim 2 , wherein
the first and second codes allocated for the first part of the RRI and first and second codes allocated for the pilot part of the non-RRI uplink control signaling are sent in the same time and frequency resource; and
the third and fourth codes allocated for the second part of the RRI, and the third and fourth codes allocated for the data part of the non-RRI uplink control signaling are sent in the same time and frequency resource.

4. The apparatus of claim 3 , wherein the non-RRI uplink control signaling is one of an acknowledgement or negative-acknowledgement signal.

5. The apparatus of claim 1 , wherein the non-RRI uplink control signaling is one of an acknowledgement or negative-acknowledgement signal.

6. A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out the steps of:
obtaining a code set that is allocated for a resource request indicator (RRI), wherein the RRI comprises a first part and a second part, and the code set comprises a first code allocated for the first part of the RRI, a second code allocated for the first part of the RRI, a third code allocated for the second part of the RRI and a fourth code allocated for the second part of the RRI, each of the foregoing first through fourth codes of the code set being allocated to the user terminal for a time slot; and
sending the RRI using the code set, wherein
in a time domain, an extended manner corresponding to the first code of the code set is identical to an extended manner corresponding to a first code allocated for a pilot part of non-RRI uplink control signaling in the time slot;
in a frequency domain, an extended manner corresponding to the second code of the code set is identical to an extended manner corresponding to a second code allocated for the pilot part of the non-RRI uplink control signaling in the time slot;
in the time domain, an extended manner corresponding to the third code of the code set is identical to an extended manner corresponding to a third code allocated for a data part of the non-RRI uplink control signaling in the time slot;
in the frequency domain, an extended manner corresponding to the fourth code of the code set is identical to an extended manner corresponding to a fourth code allocated for the data part of the non-RRI uplink control signaling in the time slot.

7. The non-transitory computer-readable storage medium of claim 6 , wherein
at least one of the first and second codes of the code set is orthogonal to the corresponding codes allocated for the pilot part of the non-RRI uplink control signaling, and
at least one of the third and fourth codes of the code set is orthogonal to the corresponding codes allocated for the data part of the non-RRI uplink control signaling.

8. The non-transitory computer-readable storage medium of claim 7 , wherein
the first and second codes allocated for the first part of the RRI, and the first and second codes allocated for the pilot part of non-RRI uplink control signaling are sent in the same time and frequency resource; and
the third and fourth codes allocated for the second part of the RRI, and the third and fourth codes allocated for the data part of the non-RRI uplink control signaling are sent in the same time and frequency resource.

9. The non-transitory computer-readable storage medium of claim 8 , wherein the non-RRI uplink control signaling is one of an acknowledgement or negative-acknowledgement signal.

10. The non-transitory computer-readable storage medium of claim 6 , wherein the non-RRI uplink control signaling is one of an acknowledgement or negative-acknowledgement signal.

11. A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out the steps of:
obtaining a first code set that is allocated for a resource request indicator (RRI) sent by a first user terminal and a second code set that is allocated for non-RRI uplink control signaling sent by a second user terminal;
detecting the RRI using the first code set; and
detecting the non-RRI uplink control signaling using the second code set,
wherein the RRI comprises a first part and a second part, the first code set comprising a first code allocated for the first part of the RRI, a second code allocated for the first part of the RRI, a third code allocated for the second part of the RRI and a fourth code allocated for the second part of the RRI, and each of the foregoing first through fourth codes of the first code set being allocated to the first user terminal for a time slot; and
wherein the non-RRI uplink control signaling comprises a pilot part and a data part, the second code set comprising a fifth code allocated for the pilot part of the non-RRI uplink control signaling, a sixth code allocated for the pilot part of the non-RRI uplink control signaling, a seventh code allocated for the data part of the non-RRI uplink control signaling and an eighth code allocated for the data part of the non-RRI uplink control signaling, and each of the foregoing fifth through eighth codes of the second code set being allocated to the second user terminal for the time slot.
