Abstract: The present disclosure provides a method for configuring transmission. Configuration information for synchronization signal and physical broadcast channel block SSB measurement sent by a base station can be received. An SSB measurement is performed based on the configuration information for SSB measurement to obtain an SSB measurement report. The SSB measurement report is sent to the base station through a first designated message in order to allow the base station to configure a set of transmission configuration indication TCI states for the terminal based on the SSB measurement report. The first designated message is configured to represent contention solution during a random access procedure.
