Claim of US Patent No. 11,032,800

1. A method performed by a base station in a wireless communication system, the method comprising:transmitting, to a terminal, configuration information including configuration information on a first channel state information-reference signal (CSI-RS) and configuration information on a second CSI-RS, wherein the first CSI-RS is associated with a reference signal received power (RSRP) reporting using higher layer signaling and the second CSI-RS is associated with a feedback of channel state information;
obtaining a plurality of downlink data symbols to be transmitted to the terminal;
identifying a resource for mapping the plurality of downlink data symbols;
mapping the plurality of downlink data symbols to the identified resource; and
transmitting, to the terminal, the mapped plurality of downlink data symbols on a physical downlink shared channel (PDSCH),
wherein a resource for the second CSI-RS is not used for mapping the plurality of data symbols and a resource for the first CSI-RS is used for mapping the plurality of data symbols.
