5.6A.1 Modulation schemes other than π/2-BPSK

For , the time-continuous signal for antenna port in SC-FDMA symbol in an uplink slot is defined by clause 5.6 with replaced by .

5.6A.2 Modulation scheme π/2-BPSK

For and π/2-BPSK modulation only 2-of-3 adjacent subcarriers are selected as described in 5.5.2.1A.2. The time-continuous signal in SC-FDMA symbol in an uplink slot is defined by

for where , , is given by Table 5.6-1, and and are respectively the modulation value for subcarrier index and for symbol , and the values of used on and are respectively obtained by subtracting from the resulting set of allocated subcarriers as described in Table 8.1.6-1 of [4], and represents the lower subcarrier index among the selected subcarriers and is the subcarrier index adjacent to it. The phase rotation is given by

where is the number of transport blocks defined in clause 8.0 of TS 36.213 [4]. If >1 and interleaving between codewords is applied according to clause 8.0 of TS 36.213 [4], then the symbol counter is reset at the start of the first PUSCH codeword transmission and incremented for each symbol during the transmission of the PUSCH codewords. For other cases, the symbol counter is reset at the start of each PUSCH codeword transmission and incremented for each symbol during the transmission of the PUSCH codeword.

The SC-FDMA symbols in a slot shall be transmitted in increasing order of , starting with , where SC-FDMA symbol starts at time within the slot.
