Simultaneous HARQ-ACK feedback and uplink transmission without dynamic grant
An apparatus of a user equipment (UE) comprises one or more baseband processors to process payload size comprising a number of feedback bits for a hybrid automatic repeat request-acknowledgement (HARQ-ACK) configuration received from a New Radio (NR) NodeB (gNB) for physical uplink shared channel (PUSCH) transmission without grant, and to determine a size of reserved resource elements (REs) and mapping pattern in accordance with the configured HARQ-ACK payload size, and to transmit uplink shared channel on PUSCH without grant which is rate-matched around the reserved REs. The UE alternatively comprises one or more baseband processors to process a downlink control information (DCI) grant received from a to schedule a PUSCH transmission, wherein the one or more baseband processors are configured for dynamic DCI grant overwriting to process a dynamic indication to interrupt the scheduled PUSCH transmission.
1. An apparatus of a user equipment (UE), comprising:
one or more baseband processors to process instructions received from a New Radio (NR) NodeB (gNB) to indicate i) a scheduling of a first uplink (UL) transmission or ii) a transmission opportunity for the first UL transmission, wherein the one or more baseband processors are further configured to process a dynamic indication to interrupt the first UL transmission and wherein a reference uplink resource (RUR) is defined and a time offset between the dynamic indication is received and the RUR accommodates an application time limited by the minimum UE processing time for PUSCH preparation supported by the UE, T proc,2 ; and
radio frequency circuitry (RF) configured to transmit the first UL transmission.
2. The apparatus of claim 1 , wherein the first UL transmission is one of:
a dynamically scheduled physical uplink shared channel (PUSCH);
a dynamically scheduled physical uplink control channel (PUCCH) carrying downlink (DL) HARQ-ACK feedback;
a transmission opportunity for a configured grant (CG) PUSCH; a transmission opportunity for PUCCH carrying uplink control information including scheduling request (SR) or channel state information (CSI) feedback;
a transmission opportunity for sounding reference signal (SRS); or
a transmission opportunity for a physical random access channel (PRACH); and
wherein the dynamic indication is carried by a UE-specific downlink control information (DCI) format.
3. The apparatus of claim 2 , wherein the first UL transmission is a dynamically scheduled PUSCH and the one or more baseband processors are to cancel the dynamically scheduled PUSCH transmission in response to the dynamic indication, wherein the dynamic indication is carried by a second DCI grant, that is received after the reception of a first DCI grant scheduling the first UL transmission, and that schedules another PUSCH transmission to start before the ending symbol of the first UL transmission.
4. The apparatus of claim 3 , wherein repetitions of the previously scheduled PUSCH are dropped when the second DCI grant schedules a same hybrid automatic repeat request (HARQ) process or another HARQ process.
5. The apparatus of claim 3 , wherein repetitions of the previously scheduled PUSCH, that do not overlap in time domain with the PUSCH with a different HARQ process that is scheduled by the second DCI grant, are not dropped.
6. The apparatus of claim 3 , wherein the second DCI grant is indicated to have a higher priority compared to the previously scheduled PUSCH.
7. The apparatus of claim 1 , wherein the dynamic indication is carried by DCI Format 2_1 with the cyclic redundancy check (CRC) scrambled with a radio network temporary identifier (RNTI).
8. The apparatus of claim 1 , wherein the application time is configured semi-statically by radio resource control (RRC) signaling.
9. The apparatus of claim 1 , wherein the dynamic indication comprises an interruption indication or a continuation indication.
10. The apparatus of claim 9 , wherein the interruption indication or the continuation indication is applicable only for uplink transmissions with repetitions.
11. The apparatus of claim 9 , wherein the interruption indication or the continuation indication is applicable only for UL transmissions spanning a certain number of minimum duration or a number of symbols for a given subcarrier spacing.
12. The apparatus of claim 9 , wherein the one or more baseband processors are to monitor for the interruption indication only when the one or more baseband processors arc configured for PUSCH transmissions with an aggregation factor greater than one for dynamically scheduled PUSCH transmission or for configured grant PUSCH transmissions.
13. The apparatus of claim 1 , wherein scheduled PUSCH transmission is interrupted based on puncturing or rate-matching to avoid transmission on interrupted resources.
14. One or more non-transitory storage media having instructions stored thereon that, when executed by an apparatus of a user equipment (UE), result in:
processing instructions received from a New Radio (NR) NodeB (gNB) to indicate i) a scheduling of a first uplink (UL) transmission or ii) a transmission opportunity for the first UL transmission; and
processing a dynamic indication to interrupt the first UL transmission, wherein a reference uplink resource (RUR) is defined and a time offset between the dynamic indication is received and the RUR accommodates an application time limited by the minimum UE processing time for PUSCH preparation supported by the UE, T proc,2 .
15. The one or more non-transitory storage media of claim 14 , wherein the first UL transmission is one of:
a dynamically scheduled physical uplink shared channel (PUSCH);
a dynamically scheduled physical uplink control channel (PUCCH) carrying downlink (DL) HARQ-ACK feedback;
a transmission opportunity for a configured grant (CG) PUSCH;
a transmission opportunity for PUCCH carrying uplink control information including scheduling request (SR) or channel state information (CSI) feedback;
a transmission opportunity for sounding reference signal (SRS); or
a transmission opportunity for a physical random access channel (PRACH);
wherein the dynamic indication is carried by a UE-specific DCI format.
16. The one or more non-transitory storage media of claim 15 , wherein the first UL transmission is a dynamically scheduled PUSCH and the one or more baseband processors are to cancel the dynamically scheduled PUSCH transmission in response to the dynamic indication, wherein the dynamic indication is to be carried by a second DCI grant, that is received after the reception of a first DCI grant scheduling the first UL transmission, and that schedules another PUSCH transmission to start before the ending symbol of the first UL transmission.
17. The one or more non-transitory storage media of claim 16 , wherein repetitions of the previously scheduled PUSCH are to be dropped when the second DCI grant schedules a same hybrid automatic repeat request (HARQ) process or another HARQ process.
18. The one or more non-transitory storage media of claim 16 , wherein repetitions of the previously scheduled PUSCH, that do not overlap in time domain with the PUSCH with a different HARQ process that is scheduled by the second DCI grant, are not to be dropped.
