1. A method, performed by a terminal device, the method comprising:
receiving, from a network device, a first group of primary synchronization signals and a second group of primary synchronization signals,
wherein:
a beam for a first primary synchronization signal at a first time is the same as a beam for a second primary synchronization signal at a second time, in each of the first group and the second group,
the second time is based on the first time and a transmission interval, and
a signal sequence of a primary synchronization signal in the first group is different from a signal sequence of a primary synchronization signal in the second group.
