Claim 0:
1. A user equipment (UE), comprising a memory and one or more processors configured to, when executing instructions stored in the memory, cause the UE to:
identify a transport block (TB) for transmission to a second UE;
generate a frequency resource indication value (FRIV) for sidelink control information (SCI) by:
determining a total number of sub-channels (NSL) in a resource pool for sidelink communication;
determining a number of sub-channels (Lsub) of the TB;
determining a first starting sub-channel index (x1) of a first retransmission of the TB;
determining a second starting sub-channel index (x2) of a second retransmission of the TB; and
determining the FRIV based on a predetermined function, FRIV
