Title:
APPARATUS AND METHOD FOR CONTROLLING UPLINK TRANSMISSION POWER IN A WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/051824
Kind Code:
A1
Abstract:
The present invention relates to an apparatus and method for controlling uplink transmission power in a wireless communication system. The method for controlling uplink transmission power for a terminal includes the steps of: calculating an uplink path loss value by the terminal in a PL measurement interval designated to measure the uplink path loss value; calculating uplink transmission power based on the uplink path loss value; and transmitting an uplink signal according to the uplink transmission power. According to the present invention, each path loss value at each uplink reception point can be independently measured in a cooperative multipoint communication environment, and the uplink transmission power can be controlled by inferring the uplink path loss value for overall multiple uplink reception points.
