If the UE is configured with shortTTI, PUCCH in this clause refers to SPUCCH defined in [3] if the HARQ-ACK is sent in response to PDSCH scheduled by DCI format 7-1A/1B/1C/1D/1E/1F/1G or if the scheduling request is sent on resources configured by higher layer parameter sr-SlotSPUCCH-IndexFH or sr-SlotSPUCCH-IndexNoFH or sr-subSlotSPUCCH-Resource for slot/subslot-based transmissions, unless otherwise noted.

If the UE is not configured with shortTTI or the UE is configured with shortTTI, and UCI is to be transmitted in a subframe, the term ‘subframe/slot/subslot’ or ‘subframe/slot’ refers to a subframe in this clause.

If the UE is configured with shortTTI, and UCI is to be transmitted in a slot, the term ‘subframe/slot/subslot’ or ‘slot/subslot’ or ‘subframe/slot’ refers to a slot in this clause.

If the UE is configured with shortTTI, and UCI is to be transmitted in a subslot, the term ‘subframe/slot/subslot’ or ‘slot/subslot’ refers to a subslot in this clause.

Throughout this clause,

– if the UE is configured with higher layer parameter shortProcessingTime and the corresponding PDCCH with CRC scrambled by C-RNTI is in the UE-specific search space, , otherwise .

– if the UE is configured with higher layer parameter shortTTI and the corresponding PDCCH/SPDCCH with DCI format 7-1A/7-1B/7-1C/7-1D/7-1E/7-1F/7-1G is detected in a subslot, if the UE is configured for subslot uplink transmissions, is given by higher layer parameter proc-TimeAdv from , otherwise.

Uplink power control controls the transmit power of the different uplink physical channels.

If a UE is configured with a LAA SCell for uplink transmissions, the UE shall apply the procedures described for PUSCH and SRS in this clause assuming frame structure type 1 for the LAA SCell unless stated otherwise.

For a UE configured with EN-DC/NE-DC and serving cell frame structure type 1, if the UE is configured with tdm-PatternConfig/tdm-PatternConfigNE-DC for the serving cell, the UE is not expected to transmit any uplink physical channel or signal in the serving cell on subframes other than offset-UL subframes, where the offset-UL subframes are determined by applying an offset value given by harq-Offset-r15 to the subframes denoted as uplink in the UL/DL configuration tdm-PatternConfig/tdm-PatternConfigNE-DC.

For a UE configured with EN-DC with primary cell frame structure type 1, if the UE is configured with tdm-PatternConfig2 for a serving cell, and if the UE indicates a capability fdd-PCellUL-TX-AllUL-Subframe-r16 (as specified in [11]), the UE transmits any uplink physical channel or signal without associated DCI if configured, in the serving cell on any uplink subframes. Otherwise, if the UE is configured with tdm-PatternConfig2 for the serving cell and if the UE does not indicate a capability fdd-PCellUL-TX-AllUL-Subframe-r16, the UE is not expected to transmit any uplink physical channel or signal without associated DCI except for PRACH in the serving cell on subframes other than offset-UL subframes, where the offset-UL subframes are determined by applying an offset value given by harq-Offset-r16 to the subframes denoted as uplink in the UL/DL configuration tdm-PatternConfig2.

For a UE configured with EN-DC with primary cell frame structure type 2, if the UE is configured with tdm-PatternConfig2 for a serving cell, and if the UE indicates a capability tdd-PCellUL-TX-AllUL-Subframe-r16 (as specified in [11]), the UE transmits any uplink physical channel or signal without associated DCI if configured, in the serving cell on any uplink subframes. Otherwise, if the UE is configured with tdm-PatternConfig2 for the serving cell and if the UE does not indicate a capability tdd-PCellUL-TX-AllUL-Subframe-r16, the UE is not expected to transmit any uplink physical channel or signal without associated DCI except for PRACH in the serving cell on subframes other than offset-UL subframes, where the offset-UL subframes are determined by applying an offset value given by harq-Offset-r16 to the subframes denoted as uplink in the UL/DL configuration tdm-PatternConfig2.

For PUSCH, the transmit power  defined in Clause 5.1.1, is first scaled by the ratio of the number of antennas ports with a non-zero PUSCH transmission to the number of configured antenna ports for the transmission scheme. The resulting scaled power is then split equally across the antenna ports on which the non-zero PUSCH is transmitted.

For PUCCH or SRS, the transmit power , defined in Clause 5.1.1.1, or is split equally across the configured antenna ports for PUCCH or SRS. is the linear value ofdefined in Clause 5.1.3.

A cell wide overload indicator (OI) and a High Interference Indicator (HII) to control UL interference are defined in [9].

For a serving cell with frame structure type 1, a UE is not expected to be configured with UplinkPowerControlDedicated-v12x0.
