초록
A method and apparatus for controlling power for uplink are provided. When a base station is moving or unable to communicate with others, at least one interference amount is estimated for a neighboring base station based on a path gain between a terminal and the neighboring base station and a transmission power of each encoding packet size and transmission format included in a candidate group related to scheduling transmission power parameters. A target interference amount is determined based on an interference amount control value and an initial target interference amount according to a processing load of a serving base station, and one interference amount is selected from estimated interference amounts based on the target interference amount. The terminal determines the transmission power based on an encoding packet size and a transmission format corresponding to the selected interference amount.
