Claim Text:
1. A method for receiving downlink data in a wireless communication system, the method comprising: determining an Energy Per Resource Element (EPRE) of a reference signal received in a transmission bandwidth of an Orthogonal Frequency Division Multiplexing (OFDM) symbol; determining a power ratio of the EPRE of the reference signal to an EPRE of a physical downlink shared channel (PDSCH) based on the transmission bandwidth; determining the EPRE of the PDSCH based on the EPRE of the reference signal and the power ratio; and demodulating the PDSCH based on the EPRE of the PDSCH, wherein the transmission bandwidth is smaller than a system bandwidth, wherein the power ratio is determined based on X, N wherein X is a number of subcarriers to which the reference signal is mapped in the transmission bandwidth, N
