  • the UE can continue repetitions (FFS can be different RV versions, FFS different MCS) for the TB until one of the following conditions is met
  • embodiments of the present disclosure are directed to introducing processing time for cancellation of ongoing repetitions (e.g., as per the cited agreement above). Additionally, the cancellation rules for the case of transmission direction conflicts with dynamic slot format indication (SFI) are considered in application to physical uplink shared channel (PUSCH) carrying medium access control (MAC) control element (CE) configured grant confirmation.
  • PUSCH physical uplink shared channel
  • MAC medium access control
  • CE control element
  • Embodiments of the present disclosure may also address this issue by applying PUSCH termination. Furthermore, in case of different HARQ processes for the ongoing CG PUSCH and scheduled overlapping dynamic PUSCH, similar repetition termination behavior may be applied.
  • repetitions scheduled by dynamic grant or configured grant may be terminated by a dynamic grant for the same TB.
  • any assumption on the incurred processing time is still missing. The processing time needs to be assumed when expecting from a UE to terminate already planned/prepared PUSCH transmissions.
  • a UE is not expected to continue repetitions of dynamically triggered or configured PUSCH transmission after‘m’ symbols counted from the symbol after the last symbol of a CORESET where DCI format 0 0 or 0 1 scheduling PUSCH transmission overlapping with ongoing/planned repetitions and where the DCI is addressed to the same HARQ process ID as the ongoing/planned repetitions.
  • the value‘m’ is N2 symbols, where N2 is the minimum UE processing time for PUSCH preparation corresponding to a given processing capability, and is further defined based on one or more of: subcarrier spacing (SCS) of the scheduling PDCCH, and the SCS of the scheduled or planned PUSCH.
  • SCS subcarrier spacing
  • a UE is not expected to continue the repetitions starting from the earliest repetition after‘m’ symbols, i.e. the UE does not terminate partial PUSCH.
  • the termination may be done in MAC layer.
  • the MAC layer currently models repetitions as separate MAC grants.
  • a UE shall skip repetitions corresponding to a HARQ process starting from the repetition that corresponds to the time domain resources indicated for PUSCH transmission via another valid UL grant for the same HARQ process.
  • the concept of“valid UL grant” implies that the UL grant indicates a slot offset (from scheduling PDCCH) and starting symbol for the PUSCH transmission such that the minimum UE processing time for the PUSCH preparation is guaranteed.
  • time gaps are described in units of symbols and related to N2 symbols as the PUSCH preparation time for simplicity, in detail this implies that the time gap from the end of the last symbol of the PDCCH carrying the DCI scheduling the PUSCH and the start of the CP of the earliest UL symbol from which point the PUSCH repetitions may be canceled is at least T pr0 c,2 (milliseconds) - where T pro c,2 is as defined in Section 6.4 of the 3GPP Technical Specification (TS) 38.214, v 15.2.0, 2018-06-29.

  • the UE in the case of dynamically scheduled (“grant-based”) PUSCH with multi-slot transmissions, the UE may be expected to terminate the remaining repetitions upon reception of another UL grant for the same HARQ process only if the NDI bit-field is toggled.
  • the UE indicates as part of capability reporting framework, whether or not the UE supports the feature of canceling one or more repetitions of PUSCH with configured with slot aggregation for dynamically scheduled PUSCH or with repK > 1 for CG PUSCH based on a subsequent UL grant as described above.
  • the capability may be indicated separately for dynamically scheduled (grant-based) PUSCH and Types 1 and 2 CG PUSCH. The capability may be further reported either on a per-UE basis or a per-band per band combination basis.
  • the dynamically scheduled PUSCH includes both scheduling by DCI format 0 0 and 0 1 of dynamic PUSCH or dynamic retransmission to configured grant, or the first configured grant resource after the activation by DCI format 0 0 and 0_l addressed to CS-RNTI.
  • PUSCH after de-activation DCI may also be considered as dynamic PUSCH (e.g., not subject to cancellation by SFI) since according to MAC procedures it should carry the MAC CE with configured grant confirmation.
  • a PUSCH resource (including any repetitions when configured with slot aggregation) in a BWP after the DCI deactivation of configured grant Type 2 is considered as dynamically scheduled PUSCH and therefore is not subject to cancellation due to transmission direction conflict with SFI.
  • “direction conflict with SFI” includes the cases wherein a dynamic SFI, carried by DCI format 2 0, may indicate at least one of the symbols overlapping with the time-domain resources to carry the PUSCH with the Configured Grant Confirmation MAC CE as either DL or flexible symbol.
  • the PUSCH carrying configured grant confirmation MAC CE triggered by deactivation DCI is treated as dynamically scheduled PUSCH and therefore is not subject to cancellation due to transmission direction conflict with SFI.
  • a UE is not expected to send MAC CE configured grant confirmation in the configured PUSCH resource before the minimum PUSCH preparation procedure time from the last symbol of a CORESET where DCI format 0 0 validated as configured grant Type 2 de activation.
  • the UE may be expected to transmit the PUSCH carrying the Configured Grant Confirmation MAC CE using the earliest transmission opportunity according to the Type 2 configured grant configuration such that the start of the CP for the first UL symbol for the transmission opportunity occurs at least T pro c,2 (milliseconds) after the end of the last symbol of the PDCCH carrying the DCI format 0 0 carrying the Type 2 CG PUSCH de-activation command.
  • the UE may be expected to transmit the PUSCH carrying the Configured Grant Confirmation MAC CE using the same frequency domain resources as indicated in the activation grant for the corresponding Type 2 CG PUSCH configuration and time domain resources as indicated by the time-domain assignment bit-field in the DCI format 0 0 carrying the de-activation command.
  • the whole repetitions sequence for CG is terminated.
  • the repetitions shall be terminated at the symbol from which another PUSCH with the same HARQ process is scheduled by DCI format 0 0 or 0 1, or at the symbol of initial repetition from which another PUSCH with different HARQ process is scheduled by DCI format 0 0 or 0 1, whichever is reached first.
  • a transmission of configured grant overlaps with dynamic PUSCH at physical layer then repetitions falling fully or partially within an interval of ‘X’ symbols from the starting symbol of the dynamic PUSCH, are dropped and remaining repetitions are transmitted.
  • the above interval of length‘X’ symbols may be defined to start from the last symbol of the dynamic PUSCH.
  • the CG PUSCH transmission may be either only initial transmission or both initial transmission and any repetition in a sequence.
