lowest order information bit ao and each suc- cessive field mapped to higher order information bits. There are two SCI formats for transmission of the SCI content as follows [4]: SCI format 0 carries 1-bit frequency hopping flag; RB assignment and hopping resource allocation [log2[1 SL ( NSL + 1) /2] bits where for PSSCH hopping Nsl_hop most significant bits (MSBs) are used to obtain the value of (i) and - NsL_hop) bits provide the resource allocation in the sub- frame. For non-hopping PSSCH, bits provide the resource allocation in the subframe. The SCI format 0 further includes 7-bit time resource pat- tern; 5-bit modulation and coding; 11-bit timing advance indication; and 8-bit group destination ID. SCI format 1 is used for the scheduling of PSSCH and carries 3-bit priority; 4-bit resource reservation; frequency resource location of initial transmission and retransmis- sion 1)/2) bits; 4-bit time gap between initial transmission and retransmission; 5-bit modulation and coding; 1-bit retransmission index; and a num- ber of reserved bits to adjust the size of SCI format 1 to 32 bits. The reserved bits are set to zero. The block of bits b(0), b(Nbit where Nbit is the number of bits transmitted on the physical sidelink control channel in one subframe are scrambled with the scrambling sequence generator initialized to Cinit = 510 at the start of each PSCCH subframe and then QPSK-modulated. Layer mapping with single antenna port and transform precoding are per- formed on complex-valued modulated symbols. Transform precoding is performed similar to LTE uplink with MRUSCH and MPUSCH parameters replaced by MPSCCH and MPSCCH values, respectively. For transmission on a single antenna port, precoding is defined by where i = 0, 1, 1 and y(0)(i) denotes the transform-precoded com- plex-valued symbols. The block of complex-valued symbols z(0), z(M's -1) are multiplied by BPSCCH in order to adjust the transmit power and are sequentially mapped, starting with z(0), to the PRBs on antenna port p that have been assigned for tran
