US 2015/0092691 A1 · METHOD OF RECEIVING DOWNLINK DATA AND WIRELESS DEVICE USING THE METHOD

Abstract

A method of receiving downlink data in a wireless communication system and a wireless device are provided. The wireless device determines energy per resource element (EPRE) of a reference signal that is received in a transmission bandwidth of an orthogonal frequency division multiplexing (OFDM) symbol and determines the power ratio of the EPRE of the reference signal to the EPRE of a Physical Downlink Shared Channel (PDSCH) on the basis of the transmission bandwidth. The wireless device determines the EPRE of the PDSCH on the basis of the EPRE of the reference signal and the power ratio and demodulates the PDSCH.
