Method and apparatus for measuring interference in wireless communication system

摘要

An interference measurement method of a terminal is provided for facilitating downlink transmission in the mobile communication system based on Distributed Antenna System (DAS) in which multiple antennas controlled by a base station are distributed within the service area of the base station. The interference measurement method includes receiving channel measurement information and interference measurement information from a base station, receiving channel state information reference signals, calculating, when the received channel state information reference signal is for channel measurement, a received signal energy based on the channel measurement information and, when the received channel state information reference signal is for interference measurement, an interference based on the interference measurement information, generating channel quality information based on the received signal energy and the interference, and transmitting the channel quality information to the base station.

1. An interference measurement method of a terminal in a wireless communication system, the method comprising:
receiving channel measurement information and interference measurement information from a base station; receiving a channel state information reference signal (CSI-RS); determining a received signal energy based on the channel measurement information and the CSI-RS; determining an interference based on the interference measurement information; generating channel quality information based on the received signal energy and the interference; and transmitting the channel quality information to the base station, wherein the interference measurement information comprises a transmit power ratio between a CSI-RS and data channel incurring interference to the terminal, and wherein the channel measurement information and the interference measurement information are independently configured for at least two transmission points, respectively.
