1. A method comprising:
detecting a plurality of synchronization signal blocks (SSBs) that are transmitted for a physical broadcast channel (PBCH), each of the SSBs having a SSB index comprising a set of bit values;
detecting, from the plurality of SSBs, a first SSB received at a first time and a second SSB received at a second time that is different from the first time;
decoding, for the first SSB of the plurality, first bit values of a first SSB index representing the first SSB and first bit values of a second SSB index representing the second SSB;
determining, based on the first time and the second time, a receive time gap between the first SSB and the second SSB;
determining, based on the receive time gap and the first bit values of the first SSB index and the first bit values of the second SSB index, at least one second bit value of the first SSB index representing the first SSB and the second SSB index representing the second SSB; and
decoding a master information block (MIB) of a target cell using the at least one second bit value as a frozen bit.
