Claims8
A signal sending method, comprising:
- determining a position and beam direction of a synchronization signal block (SSB) to be sent;
- sending the SSB according to the determined position and beam direction of the SSB;
- wherein, one SSB burst set comprises a preset quantity of repeatedly sent SSBs, and the determining the position of the SSB to be sent comprises:
- determining a candidate position of a first SSB of the preset quantity of repeatedly sent SSBs in a half frame, such that the candidate position offsets from a start point of the half frame by a fixed N quantity of orthogonal frequency division multiplexing (OFDM) symbols, wherein two adjacent SSBs of the preset quantity of repeatedly sent SSBs are spaced by 3 OFDM symbols, N is a positive integer, and there is a correspondence between a value of N and a number of times the SSB is repeatedly sent, the number of times the SSB is repeatedly sent is obtained by the value of N;
- wherein the sending the SSB according to the determined position and beam direction of the SSB comprises:
- sending a same SSB signal in different beam directions, wherein different beams correspond to different respective frequency resources.
