METHOD FOR CONTROLLING UPLINK TRANSMISSION POWER IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

摘要

The present application relates to a method for enabling a terminal to transmit a sounding reference signal (SRS) in a wireless communication system. Specifically, the method comprises the steps of selecting at least one SRS power control process of a first SRS power control process and a second SRS power control process on the basis of a terminal location area; determining the transmission power of the SRS by using at least one SRS power control process; and transmitting at least one SRS to at least one base station of a first base station and a second base station participating in base cooperation communication, using the determined SRS transmission power. The terminal location area is characterized in that the base station from which downlinks are received and the base station to which uplinks are transmitted, comprise different base station cooperation areas.

1. A method for transmitting a sounding reference signal (SRS) in a base station cooperative communication system by a terminal, the method comprising:
selecting at least one SRS power control process of a first SRS power control process and a second SRS power control process based on a region in which the terminal is located; determining transmission power of the SRS using the at least one SRS power control process; and transmitting at least one SRS with the determined SRS transmission power to at least one of a first base station and a second base station participating in base station cooperative communication, wherein the region in which the terminal is located comprises a base station cooperative region including a downlink reception target base station and an uplink transmission target base station different from each other.
