1. A method of wireless communication, further comprising:
determining, by a first user equipment (UE), system parameter information to initiate a sidelink communication;
transmitting, by the first UE in one or more first subbands of a plurality of subbands within a shared radio frequency during a first time period, the system parameter information;
communicating, by the first UE with a second UE in a second subband of the plurality of subbands during a second time period different from the first time period, sidelink data based on the system parameter information;
generating, by the first UE, synchronization signals to facilitate synchronization between the first UE and the second UE;
allocating, by the first UE, the synchronization signals to a first portion of a sidelink synchronization signal block (S-SSB),
wherein the synchronization signals comprise a primary synchronization signal followed by a secondary synchronization signal;
determining, by the first UE, a sidelink master information block (SL-MIB) that includes at least a portion of the system parameter information; and
allocating, by the first UE, the SL-MIB to a second portion of the S-SSB,
wherein the second portion follows the first portion.
