Abstract: PROBLEM TO BE SOLVED: To provide a method for deciding a feedback rate of channel quality information of a radio communication system. SOLUTION: The rate for reporting the channel quality information from a mobile station to a base station is variable as a function of the presence or absence of a transmission from the base station to the mobile station. In particular, the feedback rate from the mobile station to the base station is increased when the mobile station detects the transmission from the base station. As such, the feedback rate is slower when there is no transmission for the mobile station and faster when the mobile station is receiving data. COPYRIGHT: (C)2003,JPO

Abstract: A channel quality feedback method for wireless transmission is described in which the rate for reporting channel quality information from a mobile station to a base station is variable as a function of the number of base stations that the mobile station is communicating with.
