METHOD FOR ESTIMATING UPLINK CHANNEL

摘要

Provided are a method for estimating an uplink channel and a communication system, wherein the method for estimating the uplink channel by a terminal includes the step of receiving a first sounding reference signal setting parameter for estimating the uplink channel with a serving base station and additionally receiving a second sounding reference signal setting parameter for estimating the uplink channel with an adjacent base station from the serving base station; transmitting a first sounding reference signal generated based on the first sounding reference signal setting parameter to the serving base station; and transmitting a second sounding reference signal generated based on the second sounding reference signal setting parameter to the adjacent base station.
