Problems solved by technology

However, after the random access process is completed, the base station has to wait for a process of beam measurement configuration, beam measurement, and beam measurement report before configuring a TCI (Transmission Configuration Indication, transmission configuration indication) state set for the terminal, thereby adding The delay of TCI configuration is increased, so that the terminal cannot use the most suitable receiving beam in time, which further affects the throughput of the terminal

Abstract

The invention provides a method and a device for transmission configuration. The method is used for a terminal. A base station sends one or more synchronization signal blocks SSBs to the terminal. Themethod comprises: detecting one or more first SSBs which can trigger random access; sending a first message corresponding to each of the first SSBs, the first message being used for initiating the random access to the base station, so that the base station configures a TCI status set for the terminal according to each of the first messages. Therefore, the method and the device can improve efficiency of transmission configuration and reduce time delay.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a transmission configuration method and device. Background technique [0002] In the new-generation communication system, due to the rapid attenuation of high-frequency channels, in order to ensure coverage, it is necessary to use beam (beam)-based transmission and reception. In related technologies, the beam management process starts after the terminal completes random access and RRC (Radio Resource Control, radio resource control) connection with the base station. However, after the random access process is completed, the base station has to wait for a process of beam measurement configuration, beam measurement and beam measurement report before configuring a TCI (Transmission Configuration Indication, transmission configuration indication) state set for the terminal, thereby adding The delay of TCI configuration is increased, so that the terminal cannot...
