    Abstract: Embodiments of this application disclose a method used for data transmission. This method is applicable to coordinated transmission/reception in NR, and is relatively flexible. This method includes: determining, by a network device, a plurality of groups of antenna ports, where each group of antenna ports includes at least two antenna ports, and any two antenna ports in a same group of antenna ports meet quasi-co-location QCL; and sending, by the network device, at least one piece of first indication information to a terminal device, where the first indication information is used to determine QCL configuration information corresponding to a target antenna port used for sending first data, the QCL configuration information is used to indicate an antenna port that is QCLed with the corresponding target antenna port.

    Abstract: A precoding matrix indication method relating to the field of wireless communications technologies, an apparatus, and a system that are in a wireless communications system are provided. A combination of a plurality of stages of codebooks and a corresponding PMI feedback method are further provided. User equipment receives indication information sent by a network device, where the indication information includes information about codebooks used to report precoding matrix indicators (PMI), the information about the codebooks indicates that the used codebooks are at least two of a first codebook to an Nth codebook, the PMIs include at least two of a first PMI to an Nth PMI, and the first PMI to the Nth PMI are respectively used to indicate a precoding matrix in the first codebook to a precoding matrix in the Nth codebook; and sends the PMIs based on the indication information.

    Abstract: A power configuration method and a related device are provided. The method includes: receiving a first power configuration parameter and a second power configuration parameter from a network device; and when receiving a reference signal and data of a first antenna port group and a reference signal and data of a second antenna port group, determining, based on the first power configuration parameter and the reference signal of the first antenna port group, a power of the data that is from the first antenna port group, and determining, based on the second power configuration parameter and the reference signal of the second antenna port group, a power of the data that is from the second antenna port group, so that data sent by a corresponding antenna port group can be separately demodulated based on an obtained power, thereby improving accuracy for demodulating data of a plurality of antenna port groups.
