Abstract
Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for using block acknowledgments to acknowledge semi-persistently scheduled (SPS) occasions from multiple SPS configurations. An example method generally includes determining that a slot scheduled for reporting acknowledgment feedback for an SPS physical downlink shared channel (PDSCH) potentially overlaps with at least one downlink or flexible symbol, deciding whether to cancel or to delay reporting the acknowledgment feedback to a network entity based on one or more conditions, and canceling or delaying reporting the acknowledgment feedback to the network entity, in accordance with the decision.
Claims30
A method for wireless communications by a user equipment (UE), comprising:
- determining that a slot scheduled for reporting acknowledgment feedback for a semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) potentially overlaps with at least one downlink or flexible symbol;
- deciding whether to cancel or to delay reporting the acknowledgment feedback to a network entity based on one or more conditions related to a cause of the overlap between the SPS PDSCH and the at least one downlink or flexible symbol;
- and
- canceling or delaying reporting the acknowledgment feedback to the network entity, in accordance with the decision.
A method for wireless communications by a network entity, comprising:
- determining that a slot scheduled for a UE to report acknowledgment feedback for a semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) potentially overlaps with at least one downlink or flexible symbol;
- and
- deciding whether to monitor for the UE to delay reporting the acknowledgment feedback based on one or more conditions related to a cause of the overlap between the SPS PDSCH and the at least one downlink or flexible symbol.
An apparatus for wireless communications by a user equipment (UE), comprising:
- at least one processor and a memory configured to
- determine that a slot scheduled for reporting acknowledgment feedback for a semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) potentially overlaps with at least one downlink or flexible symbol;
- decide whether to cancel or to delay reporting the acknowledgment feedback to a network entity based on one or more conditions related to a cause of the overlap between the SPS PDSCH and the at least one downlink or flexible symbol;
- and
- cancel or delay reporting the acknowledgment feedback to the network entity, in accordance with the decision.
