EFFECTIVE FEEDBACK METHOD IN MULTIPLE ANTENNA SUPPORT WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREOF CAPABLE OF PROVIDING ENLARGED SYSTEM CAPACITY

摘要

PURPOSE: An effective feedback method in multiple antenna support wireless communication system and apparatus thereof are provided to support MIMO(Multiple Input Multiple Output) transmission by constituting feedback information.;CONSTITUTION: A terminal creates channel state information for one or more downlink carriers(S3310). The terminal determines a collision in a PUCCH(Physical Uplink Control Channel) of one or more uplink carriers(S3320). The terminal determines a transmission target CQI(Channel Quality Indicator) according to the order of priority(S3330). The terminal transmits the CQI determined from the collision of the CQI(S3340).;COPYRIGHT KIPO 2012
