Abstract: An array grouping-based communication method and a communication apparatus are provided. A first signal is received from a first communication device using M groups of analog weights, where at least two groups of analog weights in the M groups of analog weights are different, and M is an integer greater than or equal to 2. Channel estimation is performed based on the first signal to obtain M channel estimation results, where the M channel estimation results are arranged in one-to-one correspondence with the M groups of analog weights. Signal receiving or sending processing is performed based on the M channel estimation results using a target analog weight, where the target analog weight is obtained based on the M groups of analog weights.

Abstract: Embodiments of the present invention disclose a reference signal transmission method, including: sending, by a terminal, a first reference signal and a second reference signal; and correspondingly, receiving, by a network device, the first reference signal and the second reference signal, where the first reference signal is mapped to a plurality of symbols and is used for estimation of channel state information, the second reference signal is mapped to at least two of the plurality of symbols and is used for phase tracking, and a subcarrier to which the second reference signal is mapped on one of the at least two symbols has a same frequency-domain location as a subcarrier to which the second reference signal is mapped on the rest of the at least two symbols. With the foregoing solution, accuracy of channel state information estimation can be improved.

Abstract: Embodiments of the present invention relate to the communications field, and disclose an information transmission method and device to implement beamforming on an SRS. A specific solution is as follows: A base station configures at least one first resource for a UE, where the first resource is used by the UE to transmit a target channel and/or signal; and the base station transmits first indication information to the UE, where the first indication information is used to indicate a correspondence between the first resource and a beam, or the first indication information is used to indicate a correspondence between the first resource and a second resource. The embodiments of the present invention are used in a beamforming process.
