Claim of US Patent No. 11,071,078


1. A method of wireless communication, comprising:detecting a synchronization channel over a single frequency network (SFN) at a user equipment (UE), wherein the synchronization channel includes a reference signal and an encoded payload;
extracting a zone identifier (ID) embedded in the reference signal, wherein the extracting includes searching the synchronization channel using available predefined zone IDs and available time offsets until detecting the zone ID; and
in response to extracting the zone ID:synchronizing timing at the UE using the reference signal; and
decoding the encoded payload.
