               1. A method in a base station for synchronization in a wireless system comprising: 
            transmitting a Synchronization Signal Block (SSB) comprising a physical broadcast channel (PBCH) including one or more bits, wherein the SSB is one of a set of candidate SSBs within a half frame and a total number of the candidate SSBs within the half frame is an integer greater than zero and wherein the PBCH is interleaved with a downlink pilot signal sequence; 
                wherein when a frequency of the wireless system is within a frequency range up to a predefined frequency, the one or more bits indicate additional system information and when the frequency of the wireless system is above the predefined frequency, the one or more bits indicate a location of a slot group containing the SSB among the set of candidate SSBs within the half frame.
