Apparatus and method for transmitting and receiving fast feedback information in broadband wireless communication system

摘要

An apparatus and method for operating a fast feedback channel in a broadband wireless communication system are provided. The method includes generating and transmitting a feedback signal through a fast feedback channel of a first mode, determining to switch a mode of the fast feedback channel from the first mode to a second mode, transmitting a signal for requesting the mode switching of the fast feedback channel through the fast feedback channel, and generating and transmitting a feedback signal through a fast feedback channel of the second mode.

主权项

1. A method for operating a Mobile Station (MS) in a wireless communication system using a fast feedback channel supporting at least two modes of the fast feedback channel, the method comprising:
generating and transmitting a feedback signal through the fast feedback channel according to a first mode of the fast feedback channel; determining to switch a feedback mode from the first mode to a second mode of the fast feedback channel; transmitting a signal for requesting mode switching through the fast feedback channel; receiving feedback channel allocation information for permitting switching to the second mode from a Base Station (BS), the feedback channel allocation information comprising a feedback period and the second mode to be switched; and generating and transmitting a feedback signal through the fast feedback channel according to the second mode indicated by the feedback channel allocation information.
