Configured grant-based uplink transmission with transport block (TB) processing over multiple slots
Various embodiments herein provide techniques related to identifying, when a user equipment (UE) is in a fifth generation (5G) or new radio (NR) cellular network, a data that is to be transmitted in a transport block over multiple slots (TBoMS) in a configured grant (CG) physical uplink shared channel (PUSCH); identifying, based on an indication received from a base station, a number of repetitions for transmission of the PUSCH; and transmitting, based on the indication, the TBoMS in the PUSCH over the multiple slots. Other embodiments may be described and/or claimed.
1 . An apparatus for use in a user equipment (UE) configured for operation in a fifth generation (5G) new radio (NR) network (5G NR), wherein the apparatus comprises:
memory to store data that is to be transmitted in a transport block over multiple slots (TBoMS) in a configured grant (CG) physical uplink shared channel (PUSCH); and
one or more processors configured to:
identify, based on an indication received from a base station, a number of repetitions for transmission of the CG PUSCH;
facilitate, based on the indication, transmission of the TBoMS in the CG PUSCH over the multiple slots;
terminate transmission of the repetitions of the TBoMS in the CG PUSCH over the multiple slots if a repetition of the TBoMS overlaps in a first slot that is scheduled with a dynamically granted (DG) PUSCH having a same Hybrid Automatic Repeat Request (HARQ) process ID as the CG PUSCH; and
multiplex HARQ acknowledge (HARQ-ACK) feedback with aperiodic channel state information (A-CSI) for transmission in the first slot when the repetition of the TBoMS overlaps in the first slot that is scheduled with the DG PUSCH,
wherein an overlap is determined when one or more symbols of the DG PUSCH are scheduled in one more symbols that occur within an overall duration of the repetition of the TBOMS.
2 . The apparatus of claim 1 , wherein the A-CSI is only transmitted during the first slot of the multiple slots.
3 . The apparatus of claim 2 , wherein transmission of the A-CSI is based on identification, by the UE, of a downlink control information (DCI) format of a DCI received from the base station.
4 . The apparatus of claim 3 , wherein the DCI format is DCI format 0_1 or 0_2.
5 . The apparatus of claim 2 , wherein the data is transmitted on remaining ones of the multiple slots of the TBoMS.
6 . One or more non-transitory computer-readable media comprising instruction that, upon execution of the instructions by one or more processors, are to cause a User Equipment (UE) to:
identify, when the UE is in a fifth generation (5G) or new radio (NR) cellular network, a data that is to be transmitted in a transport block over multiple slots (TBoMS) in a configured grant (CG) physical uplink shared channel (PUSCH);
identify, based on an indication received from a base station, a number of repetitions for transmission of the PUSCH; and
transmit, based on the indication, the TBoMS in the PUSCH over the multiple slots;
terminate transmission of the repetitions of the TBoMS in the CG PUSCH over the multiple slots if a repetition of the TBoMS overlaps in a first slot that is scheduled with a dynamically granted (DG) PUSCH having a same Hybrid Automatic Repeat Request (HARQ) process ID as the CG PUSCH; and
multiplex HARQ acknowledge (HARQ-ACK) feedback with aperiodic channel state information (A-CSI) for transmission in the first slot when the repetition of the TBoMS overlaps in the first slot that is scheduled with the DG PUSCH,
wherein an overlap is determined when one or more symbols of the DG PUSCH are scheduled in one more symbols that occur within an overall duration of the repetition of the TBOMS.
7 . The one or more non-transitory computer-readable media of claim 6 , wherein the A-CSI is only transmitted during the first slot of the multiple slots.
8 . The one or more non-transitory computer-readable media of claim 7 , wherein transmission of the A-CSI is based on identification of a downlink control information (DCI) format of a DCI received from the base station.
9 . An apparatus for use in a base station, wherein the apparatus comprises:
one or more processors; and
one or more non-transitory computer readable media comprising instruction that, upon execution of the instructions by the one or more processors, are to cause the base station to:
transmit, to a user equipment (UE) an indication of a number of repetitions for transmission of a configured grant (CG) physical uplink shared channel (PUSCH) that includes a transmission of a transport block over multiple slots (TBoMS); and
identify, based on the indication, received transmissions of the PUSCH in the multiple slots,
wherein transmission of the repetitions of the TBoMS in the CG PUSCH over the multiple slots is terminated by the UE if a repetition of the TBoMS overlaps in a first slot that is scheduled with a dynamically granted (DG) PUSCH having a same Hybrid Automatic Repeat Request (HARQ) process ID as the CG PUSCH; and
wherein the base station is configured to receive HARQ acknowledge (HARQ-ACK) feedback multiplexed with aperiodic channel state information (A-CSI) in the first slot when the repetition of the TBoMS overlaps in the first slot that is scheduled with the DG PUSCH,
wherein an overlap is determined when one or more symbols of the DG PUSCH are scheduled in one more symbols that occur within an overall duration of the repetition of the TBOMS.
10 . The apparatus of claim 9 , wherein the A-CSI is only received from the UE in the first slot.
11 . The apparatus of claim 10 , wherein data is received from the UE in remaining slots of the multiple slots, and the A-CSI is not received from the UE in the remaining slots.
12 . The apparatus of claim 10 , wherein transmission of the A-CSI by the UE is based on a downlink control information (DCI) format of a DCI transmitted by the base station.
13 . The apparatus of claim 12 , wherein the DCI format is DCI format 0_1 or DCI format 0_2.
