Abstract
Certain aspects of the present disclosure provide techniques for processing physical downlink shared channel (PDSCH) transmissions scheduled with non-numeric timing feedback indicators.
Claims28
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor configured to:
- receive a first downlink control information (DCI) that schedules a first physical downlink shared channel (PDSCH) transmission and includes a non-numeric feedback timing indicator;
- receive a second DCI that schedules a second PDSCH transmission and includes a numeric feedback timing indicator, wherein the second DCI comprises a first detected DCI with a numeric feedback timing indicator that is detected after the first DCI that schedules the first PDSCH transmission;
- and
- determine at least one of whether to or when to transmit acknowledgment feedback for the first PDSCH transmission based at least in part on the numeric feedback timing indicator included in the second DCI, wherein:
- when the determination is to transmit acknowledgment feedback for the first PDSCH transmission, the processor is further configured to transmit acknowledgment feedback for both the first PDSCH transmission and the second PDSCH transmission in a same slot and physical uplink control channel (PUCCH) resource;
- and
- a memory coupled with the at least one processor.

An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor configured to:
- receive a first downlink control information (DCI) that schedules a physical downlink shared channel (PDSCH) transmission for a first hybrid automatic repeat request (HARQ) process ID and includes a non-numeric feedback timing indicator;
- receive a second DCI that schedules a PDSCH transmission for a second HARQ process ID;
- and
- determine when the UE can receive another DCI scheduling another PDSCH transmission for the first HARQ process ID based, at least in part, on information in the second DCI;
- and
- a memory coupled with the at least one processor.

An apparatus for wireless communications by a network entity, comprising:
- at least one processor configured to:
- send a first downlink control information (DCI) that schedules a first physical downlink shared channel (PDSCH) transmission to a user equipment (UE) and includes a non-numeric feedback timing indicator;
- send a second DCI that schedules a second PDSCH transmission and includes a numeric feedback timing indicator, wherein the second DCI comprises a first detected DCI with a numeric feedback timing indicator that is detected after the first DCI that schedules the first PDSCH transmission;
- and
- determine at least one of whether or when the UE is to transmit acknowledgment feedback for the first PDSCH transmission based at least in part on the numeric feedback timing indicator included in the second DCI, wherein:
- when the determination is the UE is to transmit acknowledgment feedback for the first PDSCH transmission, the at least one processor is configured to receive acknowledgement feedback for both the first PDSCH transmission and the second PDSCH transmission in a same slot and physical uplink control channel (PUCCH) resource, and
- a memory coupled with the at least one processor.
