Section: 5.5.2.1A.2 Reference signal sequence using π/2-BPSK modulation scheme
Content: For using π/2-BPSK modulation scheme, is used to determine which 2 of 3 subcarriers will be used: - 0 indicates that the two subcarriers having the lowest indices among the three allocated are utilized. - 1 indicates that the two subcarriers having the highest indices among the three allocated are utilized. The reference signal sequences and for using 2 out of 3 subcarriers are defined by where the binary sequence is defined by clause 7.2 and shall be initialised with at the start of the PUSCH transmission using sub-PRB allocations for BL/CE UEs. The quantity is given by Table 5.5.2.1A.2-1 where if group hopping is not enabled, and by clause 5.5.2.1A.3 if group hopping is enabled for PUSCH using sub-PRB allocations for BL/CE UEs. Table 5.5.2.1A.2-1: Definition of The reference signal sequences for PUSCH using sub-PRB allocations for BL/CE UEs is given by clause 5.3.3, where and correspond to the complex-valued symbols at the input of the transform precoding. The resulting complex-valued symbols at the output of the transform precoding correspond to the sequence which is mapped to physical resources as described in clause 5.5.2.1A.4.
