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.
