    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.

    Abstract: An adaptive multi-antenna data transmission method, apparatus, and system are provided. The adaptive multi-antenna data transmission method includes: acquiring, at a current time interval, a beam adjustment parameter of user equipment UE; adjusting a beam width of the UE according to the beam adjustment parameter of the UE; and performing precoding processing on to-be-transmitted data of the UE according to an adjusted beam width of the UE and direction information of the UE, so as to perform data transmission. A beam width of UE is adjusted, so that a direction of a beam during data transmission can better match a direction of the UE. Therefore, a status or quality of a link for the UE is improved and a performance loss is reduced.
