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.

Claim
1. A user terminal, the user terminal comprising:
a transmitter, and
a processor coupled with the transmitter, wherein
the processor being operable 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, the 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 the first code allocated for the first part of the RRI, the second code allocated for the first part of the RRI, the third code allocated for the second part of the RRI and the fourth code allocated for the second part of the RRI are allocated to the user terminal for one slot;
the transmitter being operable to send the RRI using the code set, wherein
in a time domain, an extended manner corresponding to the first code allocated for a first part of the RRI is identical to an extended manner corresponding to a first code allocated for a pilot part of non-RRI uplink control signaling;
in a frequency domain, an extended manner corresponding to the second code allocated for the first part of the RRI 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 domain, an extended manner corresponding to the third code allocated for a second part of the RRI is identical to an extended manner corresponding to a third code allocated for a data part of the non-RRI uplink control signaling; and
in the frequency domain, an extended manner corresponding to the fourth code allocated for the second part of the RRI is identical to an extended manner corresponding to a fourth code allocated for the data part of the non-RRI uplink control signaling.
2. The user terminal according to claim 1, wherein:
at least one of the first code and the second code that are allocated for the first part of the RRI is orthogonal to the corresponding code allocated for the pilot part of the non-RRI uplink control signaling, and
at least one of the third code and the fourth code that are allocated for the second part of the RRI is orthogonal to the corresponding code allocated for the data part of the non-RRI uplink control signaling.
3. The user terminal according to claim 2, wherein:
the first code allocated for the first part of the RRI, the first code allocated for the pilot part of non-RRI uplink control signaling, the second code allocated for the first part of the RRI and the second code allocated for the pilot part of the non-RRI uplink control signaling are sent in the same time and frequency resource; and
the third code allocated for the second part of the RRI, the third code allocated for the data part of the non-RRI uplink control signaling, the fourth code allocated for the second part of the RRI and the fourth code allocated for the data part of the non-RRI uplink control signaling are sent utilizing same time and frequency resource.
4. The user terminal according to claim 3, wherein the non-RRI uplink control signaling is an acknowledgement or negative-acknowledgement signal.
5. The user terminal according to claim 1, further comprising:
a receiver coupled with the processor, wherein
the receiver is operable to receive a parameter from a base station; and
the processor is operable to use the parameter to obtain the code set.
6. The user terminal according to claim 1, wherein the non-RRI uplink control signaling is an acknowledgement or negative-acknowledgement signal.
7. A method for sending a resource request indicator (RRI), comprising:
obtaining a code set that is allocated for the 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, and the first code allocated for the first part of the RRI, the second code allocated for the first part of the RRI, the third code allocated for the second part of the RRI and the fourth code allocated for the second part of the RRI are allocated to a user terminal for one slot; and
sending the RRI using the code set, wherein
in a time domain, an extended manner corresponding to the first code allocated for a first part of the RRI is identical to an extended manner corresponding to a first code allocated for a pilot part of non-RRI uplink control signaling;
in a frequency domain, an extended manner corresponding to the second code allocated for the first part of the RRI 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 domain, an extended manner corresponding to the third code allocated for a second part of the RRI 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 frequency domain, an extended manner corresponding to the fourth code allocated for the second part of the RRI is identical to an extended manner corresponding to a fourth code allocated for the data part of the non-RRI uplink control signaling.
8. The method according to claim 7, wherein:
at least one of the first code and the second code that are allocated for the first part of the RRI is orthogonal to the corresponding code allocated for the pilot part of the non-RRI uplink control signaling, and
at least one of the third code and the fourth code that are allocated for the second part of the RRI is orthogonal to the corresponding code allocated for the data part of the non-RRI uplink control signaling.
9. The method according to claim 8, wherein:
the first code allocated for the first part of the RRI, the first code allocated for the pilot part of non-RRI uplink control signaling, the second code allocated for the first part of the RRI and the second code allocated for the pilot part of the non-RRI uplink control signaling are sent utilizing same time and frequency resource; and
the third code allocated for the second part of the RRI, the third code allocated for the data part of the non-RRI uplink control signaling, the fourth code allocated for the second part of the RRI and the fourth code allocated for the data part of the non-RRI uplink control signaling are sent in the same time and frequency resource.
