Claim 3:
4. A baseband processor configured 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; and
determining the FRIV based on a predetermined function:, FRIV

encode the FRIV in the SCI; and
cause transmission of the SCI to the second UE.
