Method and apparatus for transmitting reference signal for reducing intercell interference in multiple input multiple output communication system

摘要

According to one embodiment, a method for receiving a Channel State Information-Reference Signal (CSI-RS) for measuring a channel includes: receiving CSI-RSs on resource elements (REs) in a subframe configured for the CSI-RSs from a base station, wherein if each CSI-RS of the received CSI-RSs is transmitted from each of four or more transmit antenna ports of the base station, at least two REs on which each CSI-RS is received are associated with each of the four or more transmit antenna ports; and transmitting channel state information based on the received CSI-RSs.

1. A method for receiving a Channel State Information-Reference Signal (CSI-RS) for measuring a channel, the method comprising:
receiving CSI-RSs on resource elements (REs) in a subframe configured for the CSI-RSs from a base station, wherein if each CSI-RS of the received CSI-RSs is transmitted from each of four or more transmit antenna ports of the base station, at least two REs on which each CSI-RS is received are associated with each of the four or more transmit antenna ports, and wherein the at least two REs on which the each CSI-RS is received are located only in one resource block (RB) among two RBs of the subframe and are adjacent to each other in the time domain in the one RB; and transmitting channel state information based on the received CSI-RSs.
