1. A signal transmission method performed by a terminal, comprising:
transmitting P synchronous signal blocks SSBs in a synchronous period,
wherein the P SSBs are divided into Q groups, any of the Q groups comprises at least one SSB, both P and Q are positive integers greater than or equal to 1;
when a synchronization period comprises at least two SSBs, a time-domain location of at least one of the SSBs is preconfigured or carried through a physical broadcast channel PBCH,
wherein when the time-domain location of the at least one of the SSBs is preconfigured, preconfigured information of the time-domain location comprises at least one of the following parameters:
time intervals between two adjacent SSBs in a same group;
time intervals between all SSBs in a same group and a first SSB in the group; or
time intervals between all SSBs and a first SSB in a synchronization period;
wherein the time interval is Ti slots or Ti milliseconds, Ti is greater than or equal to 0.
