SIGNAL TRANSMITTER CAPABLE OF SOLVING UNFAIRNESS PROBLEMS IN USER SELECTIONS AND A METHOD THEREOF

摘要

PURPOSE: A signal transmitter and a method thereof are provided to transmit a signal to a user selected by considering channel characteristics in an environment including a multi-antenna system.;CONSTITUTION: A feedback determination unit(309) determines the transmission state of channel information by comparing the determined threshold value with the measured channel state value. A transmitter transmits channel information to a base station by using the allocated uplink resources according to the transmission state of the channel information. A threshold value determination unit(305) determines a threshold value according to the variation information. The threshold value determination unit provides the determined threshold value to the feedback determination unit.;COPYRIGHT KIPO 2013;[Reference numerals] (301) Reception unit; (303) Channel estimation unit; (305) Threshold value determination unit; (309) Feedback determination unit; (311) Resource allocation request unit; (AA) Increase and decrease information; (BB) Normalization unit; (CC) User K
