Abstract
A communication method, an apparatus, a system, a chip, a chip module, and a storage medium are provided. A network device, such as a satellite base station, pairs a plurality of terminals based on weight vectors corresponding to main transmission directions of the plurality of terminals, configures a matrix of a group of shared reference signal weights for the paired terminals, and transmits a reference signal to the paired terminals on a reference signal port group at a plurality of time instances based on the reference signal weight matrix.
