APPARATUS FOR PERFORMING COMP COMMUNICATION USING A PRECODED SOUNDING REFERENCE SIGNAL, AND METHOD FOR SAME

摘要

Disclosed is an apparatus for performing coordinated multiple point (CoMP) communication using a precoded sounding reference signal, and a method for same. A method for performing CoMP communication using a precoded sounding reference signal according to the present invention comprises the steps of: a base station receiving, from a terminal in a neighboring cell, a sounding reference signal (SRS) precoded by a first matrix; acquiring an effective neighboring channel matrix using a hermitian matrix of the first matrix from the received SRS, and a downstream link channel matrix between the terminal and base station; and determining a precoding matrix to be transmitted to one or more terminals served by the base station on the basis of the effective neighboring channel matrix. Here, the effective neighboring channel matrix indicates a direction toward which a receiving beam should be directed such that the terminal can receive data from a serving base station thereof.
