Enhanced physical uplink control channel (PUCCH) power control

1. An apparatus of a Next Generation NodeB (gNB) operable to encode a physical uplink control channel (PUCCH) resource indicator field length for transmission to a user equipment (UE) for enhanced Ultra Reliable Low Latency Communications (URLLC) (eURLLC), the apparatus comprising:

one or more processors configured to:

determine, at the gNB, the PUCCH resource indicator field length that indicates a length of a PUCCH resource indicator field, wherein the PUCCH resource indicator field length is related to transmission of a number of PUCCH symbols for eURLLC; and

encode, at the gNB, the PUCCH resource indicator field length for transmission in downlink control information (DCI) to the UE; and

a memory interface configured to send to a memory the PUCCH resource indicator field length.

2. The apparatus of claim 1 , further comprising a transceiver configured to transmit the PUCCH resource indicator field length to the UE.

3. The apparatus of claim 1 , wherein the one or more processors are configured to encode the PUCCH resource indicator field length for transmission via radio resource control (RRC) signaling.

4. The apparatus of claim 3 , wherein the PUCCH resource indicator field length is a PUCCH resource indicator length (PUCCH-ResourceIndicatorLength) parameter included in a PUCCH configuration (PUCCH-Config) information element (IE), wherein the PUCCH resource indicator length parameter has a value of 3, 4 or 5.

5. The apparatus of claim 1 , wherein the one or more processors are configured to encode the PUCCH resource indicator field length for transmission via a medium access control (MAC) control element (CE).

6. The apparatus of claim 5 , wherein the MAC CE includes a serving cell identifier, a downlink bandwidth part (BWP) identifier, a control resource set (CORESET) identifier, and a PUCCH resource indication length that indicates the PUCCH resource indicator field length in the DCI.

7. At least one non-transitory machine readable storage medium having instructions embodied thereon for encoding a physical uplink control channel (PUCCH) resource indicator field length for transmission from a Next Generation NodeB (gNB) to a user equipment (UE), the instructions when executed by one or more processors perform the following:

determining, at the gNB, the PUCCH resource indicator field length that indicates a length of a PUCCH resource indicator field, wherein the PUCCH resource indicator field length is related to transmission of a number of PUCCH symbols for enhanced Ultra Reliable Low Latency Communications (URLLC) (eURLLC); and

encoding, at the gNB, the PUCCH resource indicator field length for transmission in downlink control information (DCI) to the UE.

8. The at least one non-transitory machine readable storage medium of claim 7 , further comprising instructions when executed perform the following: encoding the PUCCH resource indicator field length for transmission via radio resource control (RRC) signaling.

9. The at least one non-transitory machine readable storage medium of claim 8 , wherein the PUCCH resource indicator field length is a PUCCH resource indicator length (PUCCH-ResourceIndicatorLength) parameter included in a PUCCH configuration (PUCCH-Config) information element (IE), wherein the PUCCH resource indicator length parameter has a value of 3, 4 or 5.

10. The at least one non-transitory machine readable storage medium of claim 7 , further comprising instructions when executed perform the following: encoding the PUCCH resource indicator field length for transmission via a medium access control (MAC) control element (CE), wherein the MAC CE includes a serving cell identifier, a downlink bandwidth part (BWP) identifier, a control resource set (CORESET) identifier, and a PUCCH resource indication length that indicates the PUCCH resource indicator field length in the DCI.
