Abstract
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.
