Method and apparatus for releasing uplink radio resource in wireless communication system

摘要

A method and apparatus of releasing an uplink radio resource in a wireless communication system, is provided. A user equipment (UE) receives first feedback channel allocation information from a base station (BS), and allocates a uplink radio resource to a feedback channel based on the first feedback channel allocation information. The UE also receives second feedback channel allocation information including an feedback channel release command which indicate the release of the allocated uplink radio resource to the feedback channel, and transmits a release confirm message to the BS through a hybrid automatic repeat request (HARQ) feedback channel (HFBCH) for transmitting a HARQ feedback. the UE releases the allocated uplink radio resource to the feedback channel.

1. A method of releasing an uplink radio resource in a wireless communication system, the method comprising:
receiving first feedback channel allocation information from a base station (BS), the first feedback channel allocation information including a duration field set to other than 0b000 which indicates a duration of an uplink (UL) fast feedback channel; allocating the UL fast feedback channel based on the first feedback channel allocation information; receiving second feedback channel allocation information including a duration field set to 0b000 which indicates a release of the UL fast feedback channel; transmitting a release confirm message to the BS through a hybrid automatic repeat request (HARQ) feedback channel (HFBCH) for transmitting a HARQ feedback; and releasing the UL fast feedback channel, wherein a radio resource for the HFBCH comprises three distributed feedback mini-tiles (FMTs), an FMT including two subcarriers and six orthogonal frequency division multiplexing (OFDM) symbols.
