Section: 5.5.1.4 Sequence hopping
Content: Sequence hopping only applies for reference-signals of length . For reference-signals of length , the base sequence number within the base sequence group is given by . For reference-signals of length , the base sequence number within the base sequence group in slot is defined by where the pseudo-random sequence is given by clause 7.2. The parameter Sequence-hopping-enabled provided by higher layers determines if sequence hopping is enabled or not. Sequence hopping for PUSCH can be disabled for a certain UE through the higher-layer parameter Disable-sequence-group-hopping despite being enabled on a cell basis unless the PUSCH transmission corresponds to a Random Access Response Grant or a retransmission of the same transport block as part of the contention based random access procedure. For PUSCH or SPUCCH/PUCCH format 4 transmission with ≥ 6 RBs, the pseudo-random sequence generator shall be initialized with at the beginning of each radio frame where is given by clause 5.5.1.5. For SRS, the pseudo-random sequence generator shall be initialized with at the beginning of each radio frame where is given by clause 5.5.1.5 and is given by clause 5.5.1.3.
