Abstract

An apparatus and a method for transmitting/receiving downlink data channel signal transmission information in a cellular radio communication system using a Cooperative Multi-Point (CoMP) scheme are provided. In the downlink data channel signal transmission information transmission method, a Base Station (BS) transmits downlink data channel signal transmission information including information related to Resource Elements (REs) scheduled for a downlink data channel signal transmission to a User Equipment (UE), and transmits downlink data channel signal non-transmission information including information related to REs through which a downlink data channel signal is not transmitted among the REs scheduled for the downlink data channel signal transmission to the UE.

Claims

1. A method for wireless communication, the method comprising:

receiving configuration information including at least two identifications for scrambling;

receiving control information indicating a scrambling identity;

determining an identification from at least two identifications based on the scrambling identity indicated by the control information; and

identifying a reference signal based on the scrambling identity and the determined identification.
