Abstract: A weight determining method and a related apparatus, to reduce a beam gain loss caused by a beam selection deviation are described. The method includes receiving an uplink reference signal and obtaining a channel reciprocity parameter between an uplink channel and a downlink channel based on the uplink reference signal. The method further includes determining state information of the downlink channel based on the channel reciprocity parameter, carrier frequency information of the uplink channel, and carrier frequency information of the downlink channel. Moreover, the method includes determining a weight of a downlink reference signal based on the state information of the downlink channel.

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.
