11 Claims

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 (N^SL) in a resource pool for sidelink communication;

determining a number of sub-channels (L_sub) 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

encode the FRIV in the SCI; and

transmit the SCI to the second UE.
