Abstract
A method for an uplink transmission of a user equipment (UE) in a wireless communication system and the UE are provided. The method includes receiving, from a base station (BS), control signaling; grouping physical downlink shared channels (PDSCHs) based on the control signaling; determining a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK/NACK) codebook for each grouping of the PDSCHs; and transmitting HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook. The UE includes a transceiver configured to receive control signaling from a BS; and a processor configured to: group PDSCHs based on the control signaling; and determine an HARQ-ACK/NACK codebook for each group of PDSCHs, wherein the transceiver is further configured to transmit HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook.

Claim
1. A method for an uplink transmission of a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station (BS), control signaling; grouping physical downlink shared channels (PDSCHs) based on the control signaling; determining a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK/NACK) codebook for each grouping of the PDSCHs; and transmitting HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook.
2. The method of claim 1, wherein transmitting the HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook comprises:
connecting HARQ-ACK/NACK codebooks for all of the groupings of PDSCHs in a predetermined sequential order to form the HARQ-ACK/NACK codebook; and transmitting the HARQ-ACK/NACK information by a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).
3. The method of claim 1, wherein grouping PDSCHs based on the control signaling comprises:
classifying PDSCHs associated with HARQ-ACK/NACK feedback granularity of a transport block (TB) into a first group; and classifying PDSCHs associated with HARQ-ACK/NACK feedback granularity of a code block group (CBG) into a second group.
4. The method of claim 3, wherein grouping PDSCHs based on the control signaling further comprises determining HARQ-ACK/NACK feedback granularity of the PDSCHs based on downlink control information (DCI).
5. The method of claim 1, further comprising:
determining a number of bits of the HARQ-ACK/NACK for each grouping of PDSCHs based on the control signaling.
6. The method of claim 5, wherein determining the number of bits of the HARQ-ACK/NACK for each grouping of PDSCHs comprises:
determining the number of bits of the HARQ-ACK/NACK for one of the groupings of PDSCHs associated with HARQ-ACK/NACK feedback granularity of a code block group (CBG) based on a maximum value of a number of HARQ-ACK bits for each PDSCH included in the one of the groupings of PDSCHs.
7. The method of claim 5, wherein determining the number of bits of the HARQ-ACK/NACK for each grouping of the PDSCHs comprises:
determining the number of bits of the HARQ-ACK/NACK for one of the groupings of PDSCHs comprising at least one bandwidth part (BWP) to at most support transmission of 2 transport blocks (TBs) to 2 bits, if higher-layer configuration information for HARQ-ACK spatial bundling comprised in the control signaling is not provided from the BS.
8. The method of claim 5, wherein determining the number of bits of the HARQ-ACK/NACK for each grouping of PDSCHs comprises:
determining the number of bits of the HARQ-ACK/NACK for one of the groupings of PDSCHs comprising at least one bandwidth part (BWP) to at most support transmission of 2 transport blocks (TBs) to 1 bit, if higher-layer configuration information for HARQ-ACK spatial bundling comprised in the control signaling is provided from the BS.
9. A user equipment (UE), comprising:
a transceiver configured to receive control signaling from a base station (BS); and a processor configured to: group physical downlink shared channels (PDSCHs) based on the control signaling; and determine a hybrid automatic repeat request acknowledgement/negative acknowledgement (HARQ-ACK/NACK) codebook for each group of PDSCHs, wherein the transceiver is further configured to transmit HARQ-ACK/NACK information corresponding to the HARQ-ACK/NACK codebook.
10. The UE of claim 9, wherein the processor is further configured to connect the HARQ-ACK/NACK codebooks for each group of PDSCHs in a predetermined sequential order to form the HARQ-ACK/NACK codebook, and the transceiver is further configured to transmit the HARQ-ACK/NACK information by a physical uplink control channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH).

The UE of claim 9, wherein the processor is further configured to classify PDSCHs associated with HARQ-ACK/NACK feedback granularity of a transport block (TB) into a first group; and classify PDSCHs associated with HARQ-ACK/NACK feedback granularity of a code block group (CBG) into a second group.
