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.

Abstract: Provided are an information transmission method and apparatus, a communication node, and a storage medium. The information transmission method is applied by a first communication node and includes: determining transmission slots for reference signals on reference bandwidth parts, and sending channel state reporting indication information to a second communication node, where the channel state reporting indication information is used to trigger the second communication node to, based on the reference signals in the transmission slots, report on an uplink physical channel within an active bandwidth part a channel state for the reference bandwidth parts, and the reference bandwidth parts are inactive bandwidth parts whose channel state the second communication node needs to report.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying a set of sub-bands for receiving, via a set of reconfigurable intelligent surfaces (RISs), a signal. The UE may receive, via a first RIS of the set of RISs, the signal in a first sub-band of the set of sub-bands. The UE may receive, via a second RIS of the set of RISs, the signal in a second sub-band of the set of sub-bands. The UE may transmit, based at least in part on receiving the signal, RIS information indicating at least one of: first RIS information regarding the first RIS, or second RIS information regarding the second RIS. Numerous other aspects are described.
