Section: 5.5.2.1A.3 Group hopping
Content: For the reference signal for PUSCH transmission using sub-PRB allocations for BL/CE UEs, sequence-group hopping can be enabled where the sequence-group number in slot of a radio frame is defined by a group hopping pattern and a sequence-shift pattern according to where the number of reference signal sequences available for each resource unit size, is given by Table 5.5.2.1A.3-1. Table 5.5.2.1A.3-1: Definition of Sequence-group hopping can be enabled or disabled as described in clause 5.5.1.3. The group-hopping pattern is given by where for using QPSK modulation scheme. When using π/2-BPSK modulation scheme, for frame structure type 1, is the slot number of the first slot of the resource unit, and for frame structure type 2, is the frame number of the first slot of the resource unit. The pseudo-random sequence is defined by clause 7.2. The pseudo-random sequence generator shall be initialized with at the beginning of the resource unit for using π/2-BPSK modulation scheme and in every even slot for using QPSK modulation scheme. The sequence-shift pattern is given by where .
