Abstract: This application provides example signal transmission methods and communications apparatuses. One example method includes receiving first configuration information, where the first configuration information includes at least one transmission configuration indicator (TCI) state and a configuration of a tracking reference signal (TRS) of a first channel, and the TRS is a set including a plurality of channel state information reference signal (CSI-RS) resources. A quasi-colocation (QCL) parameter of the first channel is determined based on one or more of a first CSI-RS resource in a plurality of CSI-RS resources included in a first TRS in the TRS, a first TC state in the at least one TCI state, and a synchronization signal and PBCH block (SSB). The first channel is then received on the QCL parameter of the first channel.
