URLLC physical uplink control channel (PUCCH) configuration with sub-slot structure

A base station (BS), comprising:

• one or more non-transitory computer-readable media storing one or more computer-executable instructions;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media and configured to execute the one or more computer-executable instructions to cause the BS to:
• transmit, to a user equipment (UE), a configuration to configure a sub-slot structure in a slot for a plurality of physical uplink control channel (PUCCH) resources for Hybrid Automatic Repeat Request-ACKnowledgement (HARQ-ACK) feedback in response to at least one physical downlink shared channel (PDSCH) for ultra-reliable low-latency communication (URLLC);
• and
• receive, from the UE, the HARQ-ACK feedback in response to the at least one PDSCH for URLLC based on the configured sub-slot structure in the slot, wherein:
• the plurality of PUCCH resources are confined within a sub-slot, and
• each of PUCCH resource allocations for the plurality of PUCCH resources is confined within the sub-slot based on the configured sub-slot structure.

A method performed by a user equipment (UE), the method comprising:

• receiving, from a base station (BS), a configuration to configure a sub-slot structure in a slot for a plurality of physical uplink control channel (PUCCH) resources for Hybrid Automatic Repeat Request-ACKnowledgement (HARQ-ACK) feedback in response to at least one physical downlink shared channel (PDSCH) for ultra-reliable low-latency communication (URLLC);
• and
• transmitting the HARQ-ACK feedback in response to the at least one PDSCH for URLLC based on the configured sub-slot structure in the slot, wherein:
• the plurality of PUCCH resources are confined within a sub-slot, and
• each of PUCCH resource allocations for the plurality of PUCCH resources is confined within the sub-slot based on the configured sub-slot structure.
