SIGNAL TRANSMISSION METHOD AND RELATED APPARATUS

WIPO Patent Application WO/2022/067824

A1

The present application provides a signal transmission method and related apparatus. The signal transmission method comprises: a terminal device receiving a first received signal; the first received signal is pre-coded by a first reference signal according to a first channel matrix, then sent to the terminal device via a downlink channel corresponding to the terminal device, the first channel matrix being obtained according to a second channel matrix, the number of rows and/or number of columns of the first channel matrix being less than or equal to the sum of the number of receiving antennas of one or more terminal devices participating in multiple-input multiple-output (MIMO) transmission, the second channel matrix being the channel matrix of the downlink channel corresponding to one or a plurality of terminal devices; according to the first received signal, the terminal device obtaining an equivalent channel coefficient corresponding to the terminal device.
