FEEDBACK TRANSMISSION METHOD IN A WIRELESS COMMUNICATION SYSTEM INCLUDING A RS FOR IMPROVING FEEDBACK PERFORMANCE

摘要

PURPOSE: A feedback transmission method and apparatus in a wireless communication system including a RS(Relay Station) are provided to perform feedback in a PRU unit without greatly changing the feedback structure of an existing sub band unit. ;CONSTITUTION: In time p, a feedback transmission apparatus transmits feedback information about a first PRU(Physical Resource Unit) within a sub band. In time 2p, the apparatus transmits feedback information about a second PRU within the sub band. In time 3p, the apparatus transmits feedback information about a third PRU within the sub band. In time 4p, the apparatus transmits feedback information about a fourth PRU within the sub band. In time 5p, the apparatus transmits feedback information about the first PRU within the sub band again.;COPYRIGHT KIPO 2011
