Claim 0:
1. A method of receiving a Physical Downlink Shared Channel (PDSCH) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), Radio Resource Control (RRC) configuration including first information related to semi-persistent (SP) zero power-channel state information reference signal (ZP CSI-RS) resource sets each consisting of multiple ZP CSI-RS resources;
receiving, from the BS, Medium Access Control (MAC) signaling including second information for activating a SP ZP CSI-RS resource set among the SP ZP CSI-RS resource sets;
receiving a Physical Downlink Control Channel (PDCCH) carrying Downlink Control Information (DCI) scheduling the PDSCH, the DCI includes third information designating a ZP CSI-RS resource among ZP CSI-RS resources included in the SP ZP CSI-RS resource set activated based on the second information; and
receiving and decoding the PDSCH based on the first to third information,
wherein rate-matching for the PDSCH is performed on the ZP CSI-RS resource designated based on the third information among the ZP CSI-RS resources included in the SP ZP CSI-RS resource set activated based on the second information, and
wherein the PDSCH is not mapped to the ZP CSI-RS resource by the rate-matching for the PDSCH.
