1. A method implemented at a terminal device for synchronization signal block (SSB) search in a wireless network, the method comprising:
receiving, from a network device, a message containing an indication of a subcarrier spacing (SCS) of SSB, wherein the SCS of SSB maps to a plurality of SSB pattern candidates;
determining an SSB pattern from the plurality of SSB pattern candidates at least partly according to the SCS of SSB as indicated by the message and default settings of the terminal device when operating standalone, wherein the determining the SSB pattern comprises: responsive to the indicated SCS of SSB being 30 kHz and an SCS of SSB in the default settings corresponding to operating band being 15 kHz, determining that Case B of subcarrier spacing applies for the operating band; and
obtaining SSB candidate locations based on the determined SSB pattern for SSB search.
