1. A method implemented in a network device, comprising:
determining, based on at least one of a frequency range and a value of subcarrier spacing, information on a plurality of synchronization signal (SS) blocks to be transmitted by the network device, the information at least in part indicating timing information for transmitting the plurality of SS blocks; and
transmitting, based on the information, the plurality of SS blocks to at least one terminal device served by the network device,
wherein the determining the information on the plurality of SS blocks comprises determining first information on Physical Broadcast Channel (PBCH), the first information including at least one of the following: a payload size for PBCH, second information on one or more fields in PBCH, periodicity of the plurality of SS blocks, the number of scrambling sequences for PBCH, the number of demodulation reference signal (DMRS) sequences for PBCH, mapping information on the scrambling sequences for PBCH, mapping information on the DMRS sequences for PBCH,
wherein the transmitting the plurality of SS blocks comprises transmitting, based on the first information on PBCH, the plurality of SS blocks, and
wherein the determining the information on the plurality of SS blocks further comprises:
determining, based on at least one of the frequency range and the value of subcarrier spacing, a maximum number of SS blocks within a SS burst set and
determining, at least based on the maximum number of SS blocks in a SS burst set, the number of the plurality of SS blocks to be transmitted by the network device, the plurality of SS blocks being included in the maximum number of SS blocks with same indexing.
