Abstract
Provided is a method for a user equipment (UE). The method comprises receiving a downlink control information (DCI) that indicates a physical uplink control channel (PUCCH) occasion retransmission; and performing retransmission for the PUCCH occasion and HARQ-ACK codebook associated with the PUCCH occasion based on the received DCI.
Claims24
An apparatus comprising:
- processor circuitry to:
- detect, in a first slot having an index n, downlink control information (DCI) that indicates retransmission of a physical uplink control channel (PUCCH) occasion associated with a second slot having an index n-K3, wherein K3 is indicated by the DCI and the DCI further includes a PUCCH slot indicator (PSI) field, a one-shot HARQ-ACK request field, and a PUCCH priority indicator (PPI) field;
- generate, based upon detection of the DCI in the first slot, a hybrid automatic repeat request-acknowledgment (HARQ-ACK) codebook associated with the PUCCH occasion;
- detect a priority associated with the HARQ-ACK codebook;
- and
- discard, based on detection of the priority, HARQ-ACK feedback for physical downlink shared channel (PDSCH) transmissions transmitted in slots earlier than the second slot;
- and
- output the HARQ-ACK codebook for transmission;
- and
- interface circuitry coupled with the processor circuitry to enable communication.

A method comprising:
- receiving downlink control information (DCI) that indicates retransmission of a physical uplink control channel (PUCCH) occasion;
- and
- generating, for transmission, a hybrid automatic repeat request-acknowledgment (HARQ-ACK) codebook associated with the PUCCH occasion based on the DCI,
- wherein:
- the DCI includes a PUCCH slot indicator (PSI) field, a one-shot HARQ-ACK request field, and a PUCCH priority indicator (PPI) field;
- a value of the PSI field is one-to-one mapped to a value of parameter K3 that is configured by radio resource control (RRC) signaling;
- and a bit width for the PSI field is determined as [log2(I)], where I represents a number of the K3 parameter values configured by the RRC signaling.
