US 2014/0192673 A1 · UPLINK POWER CONTROLLING METHOD AND UPLINK SIGNAL RECEIVING METHOD THEREOF

Abstract

The present invention relates to an uplink power control method and apparatus and an uplink signal receiving method and apparatus using the same. According to an embodiment of the present invention, there is provided a method of receiving an uplink signal, the method of including selecting receiving points in a CoMP (Coordinated Multi-Point) system, transmitting CoMP setting information to UE, and receiving uplink transmission from the UE, wherein uplink transmission power used for the uplink transmission is controlled based on an effective path loss calculated by using at least one of path losses between the UE performing the uplink transmission and points in the CoMP system. According to the present invention, when uplink transmission power control is performed in the uplink CoMP system, path losses for a plurality of receiving points are reflected so that power control may be exactly done.
