36.2133GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical layer proceduresRelease 17TS
Offset values are defined for single codeword PUSCH transmission and multiple codeword PUSCH transmission. Single codeword subframe-PUSCH transmission offsets , and shall be configured to values according to Table 8.6.3-1,2,3 with the higher layer signalled indexes if the UE transmits no more than 22 HARQ-ACK bits on a PUSCH or if is not configured, , and , respectively. Single codeword PUSCH transmission offset shall be configured to values according to [Table 8.6.3-1] with the higher layer signalled index if the UE transmits more than 22 HARQ-ACK bits on a PUSCH and is configured.
AUL PUSCH transmission offset for AUL-UCI shall be configured to values according to Table 8.6.3-1 with the higher layer signalled index .
If the UE is configured with higher layer parameter ul-STTI-Length,
– slot-PUSCH transmission offsets, , and shall be configured via higher layer parameters betaOffsetSlot-ACK-Index, betaOffsetSlot-RI-Index, and betaOffsetSlot-CQI-Index to values according to Table 8.6.3-1, Table 8.6.3-2, and Table 8.6.3-3 with the higher layer signalled indexes if the UE transmits no more than 22 HARQ-ACK bits on a PUSCH, and , and respectively. Slot-PUSCH transmission offset shall be configured to values according to Table 8.6.3-1 with the higher layer signalled index if the UE transmits more than 22 HARQ-ACK bits on a slot-PUSCH.
– subslot-PUSCH transmission offsets, , , , and shall be configured via higher layer parameters betaOffsetSubslot-ACK-Index, betaOffset2Subslot-ACK-Index, betaOffsetSubslot-RI-Index, betaOffset2Subslot-RI-Index, and betaOffsetSubslot-CQI-Index to values according to Table 8.6.3-1, Table 8.6.3-2, and Table 8.6.3-3 with the higher layer signalled indexes , if the UE transmits no more than 22 HARQ-ACK bits on a PUSCH, and , and respectively. Subslot-PUSCH transmission offset and shall be configured to values according to Table 8.6.3-1 with the higher layer signalled index , and if the UE transmits more than 22 HARQ-ACK bits on a subslot-PUSCH. If the Beta offset indicator field in PDCCH/SPDCCH with DCI format 7-0A/7-0B is set to 0, , and , otherwise , and .
Multiple codeword PUSCH transmission offsets , and shall be configured to values according to Table 8.6.3-1,2,3 with the higher layer signalled indexes if the UE transmits no more than 22 HARQ-ACK bits on a PUSCH or if is not configured, and , respectively. Multiple codeword PUSCH transmission offset shall be configured to values according to [Table 8.6.3-1] with the higher layer signalled index if the UE transmits more than 22 HARQ-ACK bits on a PUSCH and is configured.
If the UE is configured with higher layer parameter UplinkPowerControlDedicated-v12x0 for serving cell , and if a subframe belongs to uplink power control subframe set 2 as indicated by the higher layer parameter tpc-SubframeSet-r12, then for that subframe, the UE shall use
– the higher layer indexes , , and in place of , , , and respectively in Tables 8.6.3-1,2,3, to determine , and respectively for single codeword PUSCH transmissions, and
– the higher layer indexes , , and in place of , , and respectively in Tables 8.6.3-1,2,3, to determine , and respectively for multiple codeword PUSCH transmissions.
