METHOD AND APPARATUS FOR ADAPTIVE SIGNAL TRANSMITTING

摘要

An adaptive signal transmission method and a device are provided to enable a receiving side to consider an error caused by delay time when generating feedback information, thereby offering a smoothly operated wireless communication system even under a channel condition where a user's mobility exists. A level determiner(104) determines a transmission parameter level by using channel quality measured by considering delay time taken when signals are transmitted. A signal transmitter(105) transmits information corresponding to the level. The delay time refers to a difference between a time when data is fed back to a transmission side(10) from a receiving side(100) and a time when the transmission side(10) receives the data.
