METHOD AND APPARATUS FOR TRANSMITTING CONTROL CHANNEL SIGNAL IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING COMMUNICATION SYSTEM

摘要

The present invention is a method in which a base station transmits a control channel signal in an orthogonal frequency division multiplexing (OFDM) communication system, wherein the method configures a physical resource block (PRB) from multiple resource elements (REs) for a control channel signal for scheduling, allocates at least one RE to a response channel signal, the at least one RE occupying the time domain the same as that of the RE used in a reference signal transmission in a data channel region of the PRB and occupying the frequency domain nearest to the RE used in the reference signal transmission, and transmits the control channel signal for scheduling and the response channel signal.
