Abstract
(EN)
The present disclosure discloses a beam sweeping method, a beam configuration method, a terminal, and a network device. The beam sweeping method comprises: according to at least one of the following three factors relating to a sidelink of a terminal: usage conditions of frequency bands, subcarrier spacing, and the number of synchronization signal blocks comprised in each time slot, determining the maximum number of beams in the sidelink of the terminal during beam-sweeping transmission of a synchronization signal block, wherein the synchronization signal block is a combination block combining sidelink synchronization signals and a physical sidelink broadcast channel; and performing beam-sweeping transmission of the synchronization signal block according to the maximum number of beams.
