Abstract
In order to perform uplink scheduling for a terminal, a base station receives information on uplink interference due to the terminal from neighbor base stations, transmits the information on the uplink interference to the terminal, receives information on transmission power of a feedback channel from the terminal through the feedback channel, compares the transmission power of the feedback channel and reception power of the feedback channel so as to estimate transmission loss, and performs uplink scheduling for the terminal by reflecting the transmission loss.
