    Abstract: Implementations of this application propose example methods and apparatuses for feeding back channel state information. In one example method applied to a wireless communications system, operations include receiving, by a user equipment, time configuration signaling and feedback configuration signaling, where the time configuration signaling is used to set a feedback time period and the feedback configuration signaling is used to configure one or more feedback cycles. The user equipment obtains and sends channel state information in one or more feedback cycles during the feedback time period.

    Abstract: The present disclosure provides a data processing method, apparatus, and system. The method includes: receiving N data streams sent by a network-side device, and determining a demodulation reference signal DMRS corresponding to each of the N data streams. The method also includes grouping DMRSs corresponding to the N data streams into M groups; mapping each group of DMRSs in the M groups to corresponding resource element (RE) positions, and acquiring port-related information corresponding to each group of DMRSs. The method further includes sending the port-related information corresponding to each group of DMRSs to a terminal device; adding each group of DMRSs in the M groups to data streams; and sending the data streams to which the DMRSs are added to the terminal device.
