Method and apparatus for transmitting and receiving reference signals in wireless communication
Abstract:
Methods and apparatuses for transmitting and receiving measurement reference signal (MRS) configurations in a wireless communication system. A method includes transmitting to a user equipment (UE), or receiving from a base station, information on MRS configurations that include information on an identity of an MRS, information on a set of large-scale channel properties associated with a quasi co-location (QCL) relationship for a demodulation reference signal (DMRS) of a physical downlink shared channel (PDSCH), and information on a bandwidth for the MRS. The method further includes transmitting to the UE, or receiving from a base station, downlink control information (DCI) scheduling the PDSCH and indicating an MRS configuration for the PDSCH. The set of large-scale channel properties include, based on type, one or more of doppler shift, doppler spread, average delay, and delay spread.
