Priority differentiation of SR transmissions with HARQ-ack codebooks of different service types
A UE is configured to transmit PUCCHs for respective SRs with SR transmission occasions that would overlap with a transmission of a PUCCH with subslot based HARQ-ACK information in a resource using PUCCH format 2, 3, or 4 in a subslot of a slot. The UE includes processing circuitry configured to append SR information bits to subslot based HARQ-ACK information bits using PUCCH format 2, 3, or 4. The UE includes transmitting circuity configured to transmit UCI bits, having the HARQ-ACK and SR information bits, in a PUCCH using the PUCCH resource for the subslot based HARQ-ACK information bits with PUCCH format 2, 3, or 4. A number of the SR information bits is based on a total number of SRs with all priority configurations, or SRs with high priority configurations, whose PUCCH resources overlap with the subslot based HARQ-ACK PUCCH resource in the subslot of the slot.
1. A user equipment (UE) comprising:
processing circuitry; and
transmitting circuitry, wherein
the transmitting circuitry is configured to transmit one or more physical uplink control channels (PUCCHs) for respective one or more scheduling requests (SRs) with SR transmission occasions that would overlap with a transmission of a PUCCH with hybrid automatic repeat request-acknowledgment (HARQ-ACK) information from the UE in a resource using a PUCCH format 2, or a PUCCH format 3, or a PUCCH format 4,
the processing circuitry is configured to
multiplex uplink control information (UCI) by appending SR information bits to HARQ-ACK information bits on the PUCCH with the HARQ-ACK information, wherein a number of the SR information bits is based on only the one or more PUCCHs for the respective one or more SRs with a same priority as the HARQ-ACK information,
if the PUCCH is with HARQ-ACK information with low priority and there is a positive SR with high priority to be reported, the transmitting circuitry is further configured to transmit a PUCCH for the positive SR with high priority and cancel the transmission of the PUCCH with the HARQ-ACK information with low priority, and
if the PUCCH is with the HARQ-ACK information with low priority and there is no positive SR with high priority to be reported, or if the PUCCH is with HARQ-ACK information with high priority, the transmitting circuitry is further configured to transmit multiplexed UCI bits, having the HARQ-ACK information bits and the SR information bits, in the PUCCH using the resource for the HARQ-ACK information with PUCCH format 2, PUCCH format 3, or PUCCH format 4.
2. A method by a user equipment (UE), the method comprising:
transmitting one or more physical uplink control channels (PUCCHs) for respective one or more scheduling requests (SRs) with SR transmission occasions that would overlap with a transmission of a PUCCH with hybrid automatic repeat request-acknowledgment (HARQ-ACK) information from the UE in a resource using a PUCCH format 2, or a PUCCH format 3, or a PUCCH format 4;
multiplexing uplink control information (UCI) by appending SR information bits to HARQ-ACK information bits on the PUCCH with the HARQ-ACK information, wherein a number of the SR information bits is based on only the one or more PUCCHs for the respective one or more SRs with a same priority as the HARQ-ACK information;
if the PUCCH is with HARQ-ACK information with low priority and there is a positive SR with high priority to be reported, transmitting a PUCCH for the positive SR with high priority and canceling the transmission of the PUCCH with the HARQ-ACK information with low priority; and
if the PUCCH is with the HARQ-ACK information with low priority and there is no positive SR with high priority to be reported, or if the PUCCH is with HARQ-ACK information with high priority, transmitting multiplexed UCI bits, having the HARQ-ACK information bits and the SR information bits, in the PUCCH using the resource for the HARQ-ACK information with PUCCH format 2, PUCCH format 3, or PUCCH format 4.
3. A next generation node B (gNB) comprising:
processing circuitry; and
receiving circuitry, wherein
the processing circuitry configures a UE to transmit one or more physical uplink control channels (PUCCHs) for respective one or more scheduling requests (SRs) with SR transmission occasions that would overlap with a transmission of a PUCCH with hybrid automatic repeat request-acknowledgment (HARQ-ACK) information from the UE in a resource using a PUCCH format 2, or a PUCCH format 3, or a PUCCH format 4,
the receiving circuitry is configured to receive uplink control information (UCI) multiplexed by appending SR information bits to HARQ-ACK information bits on the PUCCH with the HARQ-ACK information, wherein a number of the SR information bits is based on only the one or more PUCCHs for the respective one or more SRs with a same priority as the HARQ-ACK information,
if the PUCCH is with HARQ-ACK information with low priority and there is a positive SR with high priority to be reported, the receiving circuitry is further configured to receive a PUCCH for the positive SR with high priority and not receive the PUCCH with the HARQ-ACK information with low priority, and
if the PUCCH is with the HARQ-ACK information with low priority and there is no positive SR with high priority to be reported, or if the PUCCH is with HARQ-ACK information with high priority, the receiving circuitry is further configured to receive multiplexed UCI bits, having the HARQ-ACK information bits and the SR information bits, in the PUCCH using the resource for the HARQ-ACK information with PUCCH format 2, PUCCH format 3, or PUCCH format 4.
