Early acknowledgement feedback
Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE) generally including receiving, from a network entity, signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for the UE, successfully decoding one of the PDSCH repetitions that was transmitted before a remaining one or more of the PDSCH repetitions, and transmitting early acknowledgment feedback to a network entity indicating the successful decoding, wherein the early acknowledgment feedback is transmitted before transmission of at least one of the remaining PDSCH repetitions.
1. A method for wireless communication by a user equipment (UE) comprising:
receiving, from a network entity, signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for the UE;
successfully decoding one of the PDSCH repetitions that was transmitted before a remaining one or more of the PDSCH repetitions; and
transmitting early acknowledgment feedback to a network entity indicating the successful decoding, wherein the early acknowledgment feedback is transmitted before transmission of at least one of the remaining PDSCH repetitions.
2. The method of claim 1 , further comprising transmitting a capability report indicating that the UE supports transmitting early acknowledgment feedback.
3. The method of claim 1 , further comprising receiving an indication of whether or not the UE is to transmit early acknowledgment feedback.
4. The method of claim 1 , wherein the UE transmits the early acknowledgment feedback when the PDSCH repetition is successfully decoded before a threshold number of remaining PDSCH repetitions.
5. The method of claim 4 , further comprising receiving, from the network entity, an indication of the threshold number.
6. The method of claim 1 , wherein timing for transmitting the early acknowledgment feedback is determined relative to:
the successfully decoded PDSCH repetition; or
another one of the scheduled PDSCH repetitions.
7. The method of claim 1 , further comprising receiving, from the network entity, an indication that the network entity received the early acknowledgement feedback.
8. The method of claim 7 , wherein the indication is received via a downlink grant with a same hybrid automatic repeat request (HARQ) process ID as a HARQ ID associated with the successfully decoded PDSCH.
9. The method of claim 7 , wherein the indication comprises an explicit indication provided via a downlink control information (DCI) or a medium access control-control element (MAC-CE).
10. The method of claim 7 , wherein the indication is received via a downlink grant with a resource allocation that at least partially overlaps with a resource allocation for the PDSCH repetitions.
11. The method of claim 1 , further comprising transmitting additional acknowledgment feedback after a last of the scheduled PDSCH repetitions if the UE has not received, from the network entity, an indication the network entity received the early acknowledgment feedback.
12. A method for wireless communication by a network entity comprising:
transmitting signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for a user equipment (UE);
transmitting at least some of the PDSCH repetitions; and
receiving early acknowledgment feedback indicating successful decoding of one of the PDSCH repetitions, wherein the early acknowledgment feedback is received before transmission of at least one of the remaining PDSCH repetitions.
13. The method of claim 12 , further comprising receiving a capability report indicating that the UE supports transmitting early acknowledgment feedback.
14. The method of claim 12 , further comprising transmitting an indication of whether or not the UE is to transmit early acknowledgment feedback.
15. The method of claim 12 , wherein the network entity receives the early acknowledgment feedback when the PDSCH repetition is successfully decoded before a threshold number of remaining PDSCH repetitions.
16. The method of claim 15 , further comprising transmitting an indication of the threshold number.
17. The method of claim 12 , wherein timing for receiving the early acknowledgment feedback is determined relative to:
the successfully decoded PDSCH repetition; or
another one of the scheduled PDSCH repetitions.
18. The method of claim 12 , further comprising transmitting an indication that the network entity received the early acknowledgement feedback.
19. The method of claim 18 , wherein the indication is transmitted via a downlink grant with a same hybrid automatic repeat request (HARQ) process ID as a HARQ ID associated with the successfully decoded PDSCH repetition.
20. The method of claim 18 , wherein the indication comprises an explicit indication provided via a downlink control information (DCI) or a medium access control-control element (MAC-CE).
21. The method of claim 18 , wherein the indication is transmitted via a downlink grant with a resource allocation that at least partially overlaps with a resource allocation for the PDSCH repetitions.
22. A user equipment (UE) configured for wireless communication, comprising:
at least one memory comprising computer-executable instructions; and
one or more processors configured to execute the computer-executable instructions and cause the UE to:
receive, from a network entity, signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for the UE;
successfully decode one of the PDSCH repetitions that was transmitted before a remaining one or more of the PDSCH repetitions; and
transmit early acknowledgment feedback to a network entity indicating the successful decoding, wherein the early acknowledgment feedback is transmitted before transmission of at least one of the remaining PDSCH repetitions.
23. A network entity configured for wireless communication, comprising:
at least one memory comprising computer-executable instructions; and
one or more processors configured to execute the computer-executable instructions and cause the network entity to:
transmit signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for a user equipment (UE);
transmit at least some of the PDSCH repetitions; and
receive early acknowledgment feedback indicating successful decoding of one of the PDSCH repetitions, wherein the early acknowledgment feedback is received before transmission of at least one of the remaining PDSCH repetitions.
