Abstract: The present disclosure relates to reference signal sending methods, signal detection methods, and apparatus. One example method includes determining an initial seed parameter of a pseudo-random sequence, and generating the pseudo-random sequence based on the initial seed parameter, where the initial seed parameter is determined based on attribute information of a terminal device, determining a cyclic shift value based on the pseudo-random sequence, and determining a reference signal based on the cyclic shift value, and sending the reference signal to a network device.

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.
