Method for determining transmission power information of downlink subframe and apparatus therefor
A method for an eNB to transmit a downlink signal to a User Equipment (UE) is disclosed. The method includes transmitting information about a data transmission power within an OFDM symbol in a data region of a downlink subframe to the UE. The information about the data transmission power is determined according to a specific condition and the specific condition includes at least one of presence/absence of a Cell-specific Reference Signal (CRS) within the symbol and a modulation scheme or a Modulation and Coding Scheme (MCS) of the symbol. The downlink subframe is a Non-Zero Power Almost Blank Subframe (NZP ABS) in which signals are transmitted at a lower transmission power than a transmission power of a normal subframe on downlink.
