A communication method and apparatus are provided. The method includes: receiving configuration information from a first device, wherein the configuration information includes first information, second information, and third information, the first information is indication information of K reference signals, the second information is indication information of K first spatial filtering parameters corresponding to the K reference signals, and the third information is indication information of a channel sparse basis matrix of channels between the first device and a second device; receiving the K reference signals from the first device; and sending channel state indication information to the first device, where the channel state indication information is determined based on K received measurement values of the K reference signals, the K first spatial filtering parameters, and the channel sparse basis matrix.

Communication method and apparatus

A method includes a first device that sends a beacon message on a beacon indication resource corresponding to a first resource, where the beacon message indicates that the first resource is used by a device in a first user group and another user group cannot use all or a part of the first resource; or the first device skips sending the beacon message on the beacon indication resource corresponding to the first resource such that a device in the other user group determines that the first resource is not used by the device in the first user group and all or part of the first resource can be temporarily used by the device in the other user group.

Resource processing method, apparatus, and medium

In accordance with an embodiment, a communication method includes: sending, by a first device, a first reference signal of M (M>2) ports; and receiving, by the first device, first indication information that indicates a first precoding matrix in a target codebook. The first precoding matrix is associated with the first reference signal, and the target codebook includes at least one target precoding matrix that is a partially coherent precoding matrix or a coherent precoding matrix.
