CPC H04W 72/23 (2023.01) [H04L 1/1812 (2013.01); H04W 72/21 (2023.01)] | 28 Claims |
25. A wireless transmit/receive unit (WTRU), comprising:
a receiver and a transmitter, wherein the receiver is configured to:
receive configuration information indicating a plurality of physical uplink control channel (PUCCH) resource sets to be used for transmission of hybrid automatic repeat request (HARQ) information, wherein each of the plurality of PUCCH resource sets includes a plurality of PUCCH resources;
receive, in first downlink control information (DCI), information including (1) a first PUCCH set indication; and (2) a first resource indicator, wherein the first PUCCH set indication and the first resource indicator are separate fields in the first DCI;
receive a first physical downlink shared channel (PDSCH) transmission according to the first DCI;
receive, in second DCI, information including (1) a second PUCCH set indication and (2) a second resource indicator, wherein the second PUCCH set indication and the second resource indicator are separate fields in the second DCI;
receive a second PDSCH transmission according to the second DCI; and
a processor configured to:
determine first HARQ information associated with the first PDSCH transmission;
select a first PUCCH resource set from the plurality of PUCCH resource sets based on at least the first PUCCH set indication, and select a first PUCCH resource from the plurality of PUCCH resources of the selected first PUCCH resource set based on at least the first resource indicator;
determine second HARQ information associated with the second PDSCH transmission;
select a second PUCCH resource set from the plurality of PUCCH resource sets based on at least the second PUCCH set indication and select a second PUCCH resource from the plurality of PUCCH resources of the selected second PUCCH resource set based on at least the second resource indicator;
determine a priority for each of the first and second HARQ information;
on condition that the first PUCCH resource overlaps in time with the second PUCCH resource, and on condition that the priority of the first HARQ information is different than the priority of the second HARQ information, determine whether lower priority HARQ information is allowed to be multiplexed with higher priority HARQ information;
wherein, on condition that lower priority HARQ information is allowed to be multiplexed with higher priority HARQ information, the transmitter is configured to multiplex the first and second HARQ information and send the multiplexed first and second HARQ information in a single PUCCH transmission.
