Abstract
A method of determining uplink transmission power at a user equipment (UE) in a wireless communication system is disclosed. The method includes receiving channel status information-reference signal (CSI-RS) settings and downlink transmission power values for a plurality of transmission points (TPs) from a higher layer, receiving CSI-RSs from the plurality of TPs, estimating path loss values corresponding to the plurality of TPs based on the received CSI-RSs, determining the uplink transmission power using the estimated path loss values, and transmitting an uplink signal to one or more of the plurality of TPs based upon the determined uplink transmission power.
