APPARATUS AND METHOD FOR TRANSMITTING A REFERENCE SIGNAL IN A WIRELESS COMMUNICATION SYSTEM

摘要

A method of transmitting a reference signal by a base station in a wireless communication system is provided. The method includes: generating a plurality of reference signals for channel measurement, wherein the plurality of reference signals for channel measurement are different types; and transmitting the plurality of reference signals for channel measurement, wherein the plurality of reference signals for channel measurement are transmitted using one or more subframes as a duty cycle.

1. A method of transmitting reference signals by a base station via a downlink channel including a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) in a wireless communication system, the method comprising:
generating a plurality of reference signals for channel measurement, wherein the plurality of reference signals for channel measurement include first type channel state information reference signals (CSI-RSs) and second type CSI-RSs; and transmitting the first type CSI-RSs based on a first duty cycle and a first offset and the second type CSI-RSs based on a second duty cycle and a second offset, wherein the first duty cycle and the second duty cycle are separately configured, wherein each of the first duty cycle and the second duty cycle is set to one of available duty cycle values including 5 ms, 10 ms, 20 ms, or 40 ms, wherein the first offset and the second offset are separately configured.
