Abstract
A method for signal processing includes the following. A network device receives transmission configuration indication (TCI) state configuration information of a channel state information-reference signal (CSI-RS) from a network device, where the TCI state configuration information contains indication information of an SSB quasi co-located with the CSI-RS. The terminal device can determine transmit power of the CSI-RS according to a cell to which the SSB belongs.
