Abstract:
Disclosed is a method for a terminal deciding an uplink transmission power in a macro cell environment, comprising at least one remote radio head (RRH). The method for the terminal deciding the uplink transmission power, comprises the steps of: receiving from the base station configuration information on the base station and on a state channel information-reference signal (CSI-RS) of the at least one RRH and CSI-RS transmission power information; measuring the strength of a received signal of the CSI-RS which is received from the at least one RRH; and estimating downlink path loss that corresponds to a node that is set as a reception point or a reception RRH by using the configuration information on the CSI-RS and the CSI-RS transmission power information.
