Abstract

A method and apparatus for allocating a resource for an uplink control channel in a wireless communication system is provided. The method includes allocating a first resource for an uplink control channel and a second resource for a dynamic ranging channel. The second resource is located right after the first resource.

Claims

1. A method for allocating a resource for an uplink control channel in a wireless communication system, the method comprising:

allocating a first resource for an uplink control channel and a second resource for a dynamic ranging channel, the second resource being located right after the first resource.

2. The method of claim 1, wherein the first resource and the second resource include at least one distributed logical resource unit (DLRU) respectively, the second resource being located right after the first resource on a DLRU index in a frequency domain.

3. The method of claim 2, wherein an index of the at least one DLRU included in the first resource is smaller than an index of the at least one DLRU included in the second resource.

4. The method of claim 2, wherein the DLRU includes six distributed tiles in the frequency domain, each of the tiles including four consecutive subcarriers.

5. The method of claim 1, wherein the uplink control channel includes at least one of a ranging channel, a feedback channel, and a bandwidth request channel.

6. The method of claim 5, wherein the feedback channel includes a hybrid automatic repeat request (HARQ) feedback channel (HFBCH) carrying an acknowledgement (ACK)/non-acknowledgement (NACK) signal for HARQ feedback, and a fast feedback channel (FFBCH) carrying channel quality information (CQI) or the like.

7. The method of claim 1, further comprising allocating a third resource for a data channel over which data is transmitted, the third resource being located right after the second resource.

8. The method of claim 1, wherein the first resource and the second resource are resources for a first system, and

the first resource and the second resource are multiplexed with a fourth resource for a second system, different from the first system, through a frequency division multiplexing (FDM) scheme.

9. A method for transmitting, by a mobile station, a ranging signal in a wireless communication system, the method comprising:

transmitting a ranging signal to a base station over an allocated dynamic ranging channel, a second resource for the dynamic ranging channel being located right after a first resource for an uplink control channel.

10. The method of claim 9, wherein the first resource and the second resource include at least one distributed logical resource unit (DLRU) respectively, the second resource being located right after the first resource on a DLRU index in a frequency domain.

11. The method of claim 10, wherein an index of the at least one DLRU included in the first resource is smaller than an index of the at least one DLRU included in the second resource.

12. The method of claim 10, wherein the DLRU includes six distributed tiles in the frequency domain, each of the tiles including four consecutive subcarriers.

13. The method of claim 9, further comprising transmitting data to the base station over a data channel, a third resource for the data channel being located right after the second resource.

14. The method of claim 9, wherein the first resource and the second resource are resources for a first system, and

the first resource and the second resource are multiplexed with a fourth resource for a second system, different from the first system, through a frequency division multiplexing (FDM) scheme.

15. A mobile station in a wireless communication system, comprising:

a Radio Frequency (RF) unit configured for transmitting or receiving a radio signal; and

a processor, coupled to the RF unit, and configured for transmitting a ranging signal to a base station over an allocated dynamic ranging channel,

wherein a second resource for the dynamic ranging channel is located right after a first resource for an uplink control channel.
