TERMINAL APPARATUS FOR CONTROLLING DOWNLINK TRANSMISSION POWER AND METHOD FOR SAME

摘要

A terminal apparatus for controlling downlink signal transmission power and a method for same are disclosed. The present invention is a method and a terminal apparatus for transmitting downlink transmission power, a method for the base station controlling the downlink transmission power in a wireless communication system comprising the steps of: transmitting a physical downlink shared channel (PDSCH) to the terminal through a carrier comprising orthogonal frequency distribution multiplexing (OFDM) symbols which do not have a cell-specific reference signal (CRS); and transmitting an upper layer parameter for controlling the transmission power of the physical downlink shared channel (PDSCH), wherein the upper layer parameter comprises information on at least one of PDSCH energy per resource element (EPRE), channel state information reference signal (CSI-RS) EPRE, and demodulation reference signal (DM-RS) EPRE.

1. A method for controlling downlink transmit power of a downlink signal transmitted from a base station (BS) through a carrier including orthogonal frequency distribution multiplexing (OFDM) symbols including no cell-specific reference signal (CRS) in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE) a power parameter for controlling transmit power of a physical downlink shared channel (PDSCH); and transmitting, to the UE, the PDSCH using the transmit power of the PDSCH, wherein the power parameter includes at least one of PDSCH energy per resource element (EPRE), channel state information reference signal (CSI-RS) EPRE and demodulation reference signal (DMRS) EPRE, wherein the power parameter is calculated based on an OFDM symbol having a reference signal including at least one of a CSI-RS and a DMRS and an OFDM symbol including no reference signal.
