摘要:
The present disclosure relates to a pre-5 th -Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4 th -Generation (4G) communication system such as Long Term Evolution (LTE). A base station and a method thereof, the method comprising: transmitting, to a user equipment, UE, through a radio resource control, RRC, signaling, information of one or more measurement reference signal, MRS, configurations for quasi co-location, QCL, with a demodulation reference signal, DM-RS, of a physical downlink shared channel, PDSCH, wherein each MRS configuration of the one or more MRS configurations includes: identification information for a MRS, and information on a set of large scale channel properties; and transmitting, to the UE, downlink control information, DCI, including indication information on a physical downlink control channel, PDCCH, wherein the indication information indicates a MRS configuration for PDSCH scheduled by the DCI among the one or more MRS configurations.
