Abstract
Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for using block acknowledgments to acknowledge SPS occasions from multiple SPS configurations.
Claims20
A method for wireless communications by a user equipment (UE), comprising:
- receiving multiple semi persistently scheduled (SPS) configurations, each SPS configuration allocating the UE with a set of periodic SPS occasions for physical downlink shared channel (PDSCH) transmissions;
- monitoring the SPS occasions of the SPS configurations;
- transmitting one or more block acknowledgments (BAs), each BA providing hybrid automatic repeat request (HARQ) feedback for multiple SPS occasions of one or more of the SPS configurations that occur within an acknowledgment window, wherein:
- the one or more BAs include at least one shared BA that provides HARQ feedback for SPS occasions of multiple SPS configurations;
- the at least one shared BA is used to provide negative acknowledgments (NAKs) only;
- and
- resources for the at least one shared BA are allocated based on a maximum number of SPS occasions that occur in the acknowledgment window;
- and
- transmitting, with the at least one shared BA, information identifying which SPS occasions are being negatively acknowledged, the information comprising unique identifiers (IDs) corresponding to each of the SPS occasions being negatively acknowledged.

A method for wireless communications by a network entity, comprising:
- transmitting, to a user equipment (UE), multiple semi persistently scheduled (SPS) configurations, each SPS configuration allocating the UE with a set of periodic SPS occasions for physical downlink shared channel (PDSCH) transmissions;
- transmitting PDSCHs in at least some of the SPS occasions of the SPS configurations;
- monitoring for one or more block acknowledgments (BAs) from the UE, each BA providing hybrid automatic repeat request (HARQ) feedback for multiple SPS occasions of one or more of the SPS configurations that occur within an acknowledgment window;
- and
- in response to the monitoring:
- receiving the one or more BAs from the UE, wherein:
- the one or more BAs include at least one shared BA that provides HARQ feedback for SPS occasions of multiple SPS configurations;
- the at least one shared BA is used to provide negative acknowledgments (NAKs) only;
- and
- resources for the at least one shared BA are allocated based on a maximum number of SPS occasions that occur in the acknowledgment window;
- and
- receiving, with the at least one shared BA, information identifying which SPS occasions are being negatively acknowledged, the information comprising unique identifiers (IDs) corresponding to each of the SPS occasions being negatively acknowledged.

A user equipment (UE) configured for wireless communications, comprising:
- a memory comprising computer-executable instructions;
- and
- one or more processors, individually or collectively, configured to execute the computer-executable instructions and cause the UE to:
- receive multiple semi persistently scheduled (SPS) configurations, each SPS configuration allocating the UE with a set of periodic SPS occasions for physical downlink shared channel (PDSCH) transmissions;
- monitor the SPS occasions of the SPS configurations;
- transmit one or more block acknowledgments (BAs), each BA providing hybrid automatic repeat request (HARQ) feedback for multiple SPS occasions of one or more of the SPS configurations that occur within an acknowledgment window, wherein:
- the one or more BAs include at least one shared BA that provides HARQ feedback for SPS occasions of multiple SPS configurations;
- the at least one shared BA is used to provide negative acknowledgments (NAKs) only;
- and
- resources for the at least one shared BA are allocated based on a maximum number of SPS occasions that occur in the acknowledgment window;
- and
- transmit, with the at least one shared BA, information identifying which SPS occasions are being negatively acknowledged, the information comprising unique identifiers (IDs) corresponding to each of the SPS occasions being negatively acknowledged.
