    Abstract: This application provides an antenna detection method, an apparatus, a device, and a storage medium. The method includes: A first terminal device sends a first detection signal to a network device. The first detection signal is used to determine at least one first antenna sub-array corresponding to the first terminal device. A plurality of antenna sub-arrays of the network device include the at least one first antenna sub-array. A time interval at which the first detection signal is sent is related to spatial non-stationary coherence time. The first terminal device obtains first information from the network device. The first information indicates to perform information transmission through the at least one first antenna sub-array corresponding to the first terminal device.

    Abstract: This application provides a communication method and apparatus, and relates to the field of communication technologies. In the method, a first communication apparatus determines a first index indicating a first precoding vector, and sends the first index to a second communication apparatus. The second communication apparatus receives the first index from the first communication apparatus, determines the first precoding vector based on the first index, and precodes data based on the first precoding vector. The first precoding vector includes spatial angle information and spatial depth information of a channel between the first communication apparatus and the second communication apparatus.

    Abstract: This application provides a communication method and a communication apparatus. The method includes: A terminal device obtains first indication information and downlink channel information, where the first indication information indicates a first path domain parameter, the first path domain parameter is a path domain parameter shared by a first uplink channel and a first downlink channel, and the first uplink channel and the first downlink channel are channels for communication between a network device and the terminal device. The terminal device estimates a second path domain parameter based on the first path domain parameter and the downlink channel information, and sends the second path domain parameter to the network device. The first path domain parameter and the second path domain parameter are used by the network device to reconstruct the first downlink channel.

    Abstract: This application provides example data dimension reduction methods, apparatus, and systems, computer devices, and storage mediums, and relates to the communications field. One example method includes receiving an antenna domain received signal, where the antenna domain received signal includes an uplink signal that is received from UE by an array antenna corresponding to an RRS, wherein the antenna domain received signal is a time domain signal, a dimension of the antenna domain received signal is N1, and N1 is an integer greater than 1. A received beam weight is obtained based on channel information of the UE. Dimension reduction is performed on the antenna domain received signal by using the received beam weight to obtain a beam domain received signal, where the beam domain received signal is a frequency domain signal, a dimension of the beam domain received signal is N2, and 0

    Abstract: The present disclosure relates to coordinated multipoint wireless communications methods. One example method includes predicting a first delay difference between receiving, by a terminal device, downlink data from a beam A of a first node and receiving, by the terminal device, the downlink data from a beam B of a second node, where the terminal device is located in a coverage area in which the beam A intersects with the beam B, and determining a first adjustment time period based on the first delay difference, where the first adjustment time period is used to adjust a transmission time in which the first node transmits the downlink data to the terminal device by using the beam A.
