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.

Communication method, apparatus, chip, storage medium, and program product

In a method, a terminal device reports, to a network device, a full-power transmission codebook subset corresponding to a frequency band supported by the terminal device before transmission channel switching. The network device or the terminal device in a communications system may determine, according to a specified rule and full-power transmission codebook subsets corresponding to a plurality of source frequency bands, a full-power transmission codebook subset corresponding to a target frequency band after transmission channel switching. The plurality of source frequency bands are frequency bands in which a plurality of target antenna ports are located before antenna port switching, and the plurality of target antenna ports are antenna ports in the target frequency band after antenna port switching.

Method for determining full-power transmission codebook subset and device

In accordance with an embodiment, a method includes sending a first message to a network device includes capability information of a terminal device that indicates antenna ports supported by P frequency domain units of the terminal device, and an antenna port supported by an ifrequency domain unit in the P frequency domain units includes an antenna port associated with the ifrequency domain unit and an antenna port that can be switched to the ifrequency domain unit in antenna ports associated with Nfrequency domain units in the P frequency domain units; and receiving configuration information from the network device, where the configuration information configures at least two sounding reference signal (SRS) resources for a first frequency domain unit of the terminal device, and the first frequency domain unit is associated with first uplink transmission configuration information.
