Claim 0:
1. An apparatus for a user equipment (UE) configured for operation in a fifth-generation system (5GS), the apparatus comprising: processing circuitry; and memory,
wherein the processing circuitry is configured to:
decode radio-resource control (RRC) configuration information to configure the UE with a first hybrid-automatic repeat request (HARQ) acknowledgement (ACK) (HARQ-ACK) codebook for first priority HARQ-ACK bits and configure the UE with a second HARQ-ACK codebook for second priority HARQ-ACK bits,
the configuration information indicating a first physical uplink control channel (PUCCH) configuration for a first PUCCH resource for the first HARQ-ACK codebook and a second PUCCH configuration for a second PUCCH resource for the second HARQ-ACK codebook; and
multiplex the first priority HARQ-ACK bits and the second priority HARQ-ACK bits in a PUCCH transmission when the first and second PUCCH resources overlap in time,
wherein the processing circuitry is configured to select a resultant PUCCH resource based on the second PUCCH configuration to multiplex the first priority HARQ-ACK bits and the second priority HARQ-ACK bits when the second priority has a priority index of one and the first priority has a priority index of zero,
wherein when the second PUCCH resource configuration is sub-slot based and the second PUCCH resource has a duration of less than a slot, the resultant PUCCH resource is selected to at least one of:
extend in time beyond the second PUCCH resource to a sub-slot boundary within a slot that includes the second PUCCH resource when the second PUCCH resource ends before the sub-slot boundary; and
extend in frequency beyond a frequency of the second PUCCH resource within the slot,
wherein the memory is configured to store the configuration information.
