METHOD FOR INSTRUCTING USER TO USE PARTICULAR DMRS ANTENNA PORT IN RADIO COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method that efficiently notifies a UE of DMRS resource allocation information necessary to receive a downlink traffic signal in an LTE-A system, and effectively notifies the UE which DMRS resources are used for transmission to another UE in the same frequency section and time section as the UE.SOLUTION: The present invention relates to a method for interpreting control information in a radio communication system including a terminal and a base station, and includes: a reception stage of receiving, from the base station, control information including information on at least one or more transmission blocks from a terminal base station and instruction information on DMRS antenna port allocation; a confirmation stage of confirming the number of transmission blocks allocated to the terminal by using the control information; and an interpretation stage of interpreting the instruction information on DMRS antenna port allocation by the number of transmission blocks.
