System and method for physical uplink shared channel (PUSCH) repetition termination in new radio (NR)
Certain embodiments are directed to a system and method of physical uplink shared channel (PUSCH) transmission termination. The system and method can include a user equipment (UE) that can receives a downlink control information (DCI) scheduling a PUSCH transmission overlapped with repetitions of a hybrid automatic repeat request (HARQ) process for the UE and terminates the PUSCH transmission upon detection of the DCI after a fixed number of symbols where the fixed number of symbols is counted from a symbol after the last symbol of a control resource set (CORESET).
1. A method of physical uplink shared channel (PUSCH) transmission termination comprising:
generating, by a user equipment (UE) as part of a capability reporting framework, an indication that the UE supports terminating a PUSCH transmission for a dynamically scheduled PUSCH;
reporting, by the UE, the indication as part of the capability reporting framework;
receiving, by the UE, a downlink control information (DCI) scheduling the PUSCH transmission that overlaps with one or more repetitions of a hybrid automatic repeat request (HARQ) process for the UE; and
terminating, by the UE, the PUSCH transmission upon detection of the DCI after a fixed number of symbols, wherein the fixed number of symbols is counted from a symbol after a last symbol of a control resource set (CORESET) of the DCI.
2. The method of claim 1 , wherein the fixed number of symbols is equal to a PUSCH preparation time corresponding to a given processing capability.
3. The method of claim 1 , further comprising skipping, by the UE, the one or more repetitions of the HARQ process starting from a repetition that corresponds to time domain resources indicated for the PUSCH transmission via a valid uplink (UL) grant for the HARQ process.
4. The method of claim 3 , wherein terminating the PUSCH transmission is based on receipt of a further valid UL grant for the HARQ process and a new data indicator (NDI) bit-field being toggled.
5. The method of claim 1 , further comprising not terminating, by the UE, the PUSCH transmission based on receipt of a slot format indication (SFI) indicating a conflicting transmission.
6. The method of claim 5 , wherein the conflicting transmission includes a conflict between at least one symbol of the SFI overlapping with a time-domain resource carrying a PUSCH configured grant confirmation medium access control (MAC) control element (CE).
7. The method of claim 1 , wherein:
the indication separately indicates whether the UE supports terminating the PUSCH transmission for slot aggregation for the dynamically scheduled PUSCH and for Types 1 and 2 cell group (CG) PUSCH.
8. A non-transitory computer readable medium having instructions stored thereon that, when executed by a user equipment (UE), cause the UE to perform operations, the operations comprising:
generating, as part of a capability reporting framework, an indication that the UE supports terminating a physical uplink shared channel (PUSCH) transmission for a dynamically scheduled PUSCH;
reporting the indication as part of the capability reporting framework;
receiving a downlink control information (DCI) scheduling the PUSCH transmission that overlaps with one or more repetitions of a hybrid automatic repeat request (HARQ) process for the UE; and
terminating the PUSCH transmission upon detection of the DCI after a fixed number of symbols, wherein the fixed number of symbols is counted from a symbol after a last symbol of a control resource set (CORESET) of the DCI.
9. The non-transitory computer readable medium of claim 8 , wherein the fixed number of symbols is equal to a PUSCH preparation time corresponding to a given processing capability.
10. The non-transitory computer readable medium of claim 8 , wherein the operations further comprise skipping the one or more repetitions of the HARQ process starting from a repetition that corresponds to time domain resources indicated for the PUSCH transmission via a valid uplink (UL) grant for the HARQ process.
11. The non-transitory computer readable medium of claim 10 , wherein the operations further comprise terminating the PUSCH transmission based on receipt of a further valid UL grant for the HARQ process and a new data indicator (NDI) bit-field being toggled.
12. The non-transitory computer readable medium of claim 8 , wherein the operations further comprise not terminating the PUSCH transmission based on receipt of a slot format indication (SFI) indicating a conflicting transmission.
13. The non-transitory computer readable medium of claim 12 , wherein the conflicting transmission includes a conflict between at least one symbol of the SFI overlapping with a time-domain resource carrying a PUSCH configured grant confirmation medium access control (MAC) control element (CE).
14. The non-transitory computer readable medium of claim 8 , wherein:
the indication separately indicates whether the UE supports terminating the PUSCH transmission for slot aggregation for the dynamically scheduled PUSCH and for Types 1 and 2 cell group (CG) PUSCH.
15. A user equipment (UE) comprising:
radio front end circuitry configured to perform wireless communication; and
processor circuitry, coupled to the radio front end circuitry, configured to:
generate, as part of a capability reporting framework, an indication that the UE supports terminating a physical uplink shared channel (PUSCH) transmission for a dynamically scheduled PUSCH;
report the indication as part of the capability reporting framework;
receive, using the radio front end circuitry, a downlink control information (DCI) scheduling the PUSCH transmission that overlaps with one or more repetitions of a hybrid automatic repeat request (HARQ) process for the UE; and
terminate the PUSCH transmission upon detection of the DCI after a fixed number of symbols, wherein the fixed number of symbols is counted from a symbol after a last symbol of a control resource set (CORESET) of the DCI.
16. The UE of claim 15 , wherein the fixed number of symbols is equal to a PUSCH preparation time corresponding to a given processing capability.
17. The UE of claim 15 , wherein the processor circuitry is further configured to skip the one or more repetitions of the HARQ process starting from a repetition that corresponds to time domain resources indicated for the PUSCH transmission via a valid uplink (UL) grant for the HARQ process.
18. The UE of claim 17 , wherein the processor circuitry is further configured to terminate the PUSCH transmission based on receipt of a further valid UL grant for the HARQ process and a new data indicator (NDI) bit-field being toggled.
19. The UE of claim 15 , wherein the processor circuitry is further configured to not terminate the PUSCH transmission based on receipt of a slot format indication (SFI) indicating a conflicting transmission.
20. The UE of claim 15 , wherein:
the indication separately indicates whether the UE supports terminating the PUSCH transmission for slot aggregation for the dynamically scheduled PUSCH and for Types 1 and 2 cell group (CG) PUSCH.
