Terminal apparatus for controlling uplink signal transmission power and method for same

摘要

A terminal apparatus for controlling uplink signal transmission power and a method for same are disclosed. A method for the terminal, which communicates with a plurality of cooperation nodes that are controlled by one base station in one cell, controlling the uplink signal transmission power in a wireless communication system comprises the steps of: receiving diversity gain information of the plurality of cooperation nodes; determining the uplink transmission power of the uplink signal by considering the diversity gain information; and transmitting the uplink signal at the uplink transmission power that is decided, wherein the diversity gain information is an offset value which considers a diversity margin of the plurality of cooperation nodes.

1. A method for controlling uplink transmit (Tx) power of a terminal communicating with a plurality of cooperation nodes controlled by one base station in one cell in a wireless communication system, the method comprising:
receiving diversity gain information of the plurality of cooperation nodes; determining uplink Tx power of an uplink signal in consideration of the diversity gain information; and transmitting the uplink signal with the determined uplink Tx power, wherein the diversity gain information is an offset value, wherein the offset value is set considering a diversity margin of the plurality of cooperation nodes when the plurality of cooperation nodes and the terminal have identical link characteristics, and wherein the offset value is set considering a diversity margin of a node having a comparatively poor link among the plurality of cooperation nodes when the plurality of cooperation nodes and the terminal have different link characteristics.
