nComa maximum number of cyclic shifts is NSRS max = 12 when KTC = 4 and NSRS max =8 when KTC=2_[6]. The sequence group is defined as = and the sequence number V depends on the higher layer parameter groupOrSequenceHopping in the SRS-Config information element. Furthermore, the SRS sequence identity nSRS is given by the higher layer parameter sequenceId in the SRS-Config information element. If groupOrSequenceHopping parameter indicates neither group nor sequence hopping, fgh(nslot, l') = and v=0 are used; otherwise, if parameter groupOrSequenceHopping indicates groupHopping, group hopping is used and fgh(nslot,l' = 30 and V = 0 where the pseudo-random sequence c(i) is initialized with Cinit nSBS at the beginning of each radio frame. If parameter groupOrSequenceHopping indicates sequenceHopping, sequence hopping is used and fgh(nslot, l') = 0 and V = for ISRS - 6NRB , otherwise, v=0. The pseudo-random sequence c(i) is initialized similar to the group hopping case [6]. Each SRS is transmitted on a designated SRS resource, and the SRS sequence r(pi)(n, l') for each OFDM symbol l' and antenna port pi is multiplied by a scaling factor BSRS to adjust its transmit power. The scaled sequence is then sequentially mapped to resource elements (k,1) starting with r(pi)(0, 1') in a slot for each antenna port such that = 0,1, , MRS and = 0,1, NSRS - 1 The length of the SRS sequence is [6]. The frequency-domain starting position k(p) defined bykicM where BSRS denotes the SRS + KTC/2) mod KTC if max /2,..., NSRS max NSRS otherwise, KLPI = ktc [6]. The frequency domain shift value nshift adjusts the SRS allocation with respect to the common resource block grid. The transmission comb offset KTC E {0, 1, KTC - 1} is con- tained in the higher layer parameter transmissionComb in the SRS-Config information element and nb is a frequency position index. Frequency hopping of the SRS is configured by the parameter bhop E {0, 1, 2, 3}. If bhop > BSRS, frequency hopping is disabled and the frequency position index nb is set to a constant as
