d = wi(m)r(a)(n) where n = 0, 1, NRB - 1, m = 0, 1, and m' =0 when intra - slot frequency hopping is enabled; otherwise, m' In the latter equation, the number of the DM-RS symbols NSF,m', orthogonal sequence wi(m), and the pseudo-random sequence (n) are given in [6]. The DM-RS sequence is multiplied by the scaling factor BPUCCH,1 in order to adjust the transmit power and is sequentially mapped starting with z(0) to resource elements (k, 1) in a slot on a single-antenna port such that = l = 0, 2, 4, wherein l = 0 corresponds to the first OFDM symbol of the PUCCH transmis- sion and (k,1) is within the resource blocks assigned for PUCCH transmission [8]. The DM-RS sequence corresponding to PUCCH format 2, IDD-RS(m, I) is generated as - sequence c(i) is mod 231. Index l is the OFDM symbol number within the slot, nslot is the slot number within the radio frame, and NO {0, 65535}. The PUCCH format 2 DM-RS sequence scaled with the scaling factor BPUCCH,2 to adjust the transmit power [8] and is sequentially mapped starting with r(0) to resource elements (k,1) in a slot on a single-antenna port such that akill = k = 3m + 1 where the frequency index k is defined relative to subcarrier 0 of common resource block 0 and (k,l) is within the resource blocks assigned for PUCCH transmission [6]. The DM-RS sequence corresponding to PUCCH format 3/4 r'DM-RS(m,I) is generated according to r'DM-RS(m, = 0, 1, ,MPUCCH,s 1 where the number of subcar- riers for this PUCCH format MPUCCH,S and the pseudo-random are given in [6]. The cyclic shift a varies with the symbol number and slot number with mo = 0 for PUCCH for- mat 3. The PUCCH format 3/4 DM-RS sequence is multiplied by the scaling factor BPUCCH,S wherein S E {3,4} to adjust the transmit power and is sequentially mapped starting with to resource elements (k,l) on a single-antenna port such that m=0,1,.
