User equipments, base stations and signaling for uplink configured scheduling of non-terrestrial networks
A user equipment (UE) is provided. The UE receives a configuration for a configured grant (CG) physical uplink shared channel (PUSCH) in a non-terrestrial network (NTN). The UE also receives first information indicating whether Hybrid Automatic Repeat Request (HARQ) feedback is disabled for the CG PUSCH, and second information indicating a timing offset for the CG PUSCH. The UE transmits the CG PUSCH based on the configuration and the second information. The UE also flushes a data buffer of the CG PUSCH based on the first information.
1 . A User Equipment (UE), comprising:
receiving circuitry configured to receive;
a configuration for a configured grant (CG) physical uplink shared channel (PUSCH) in a non-terrestrial network (NTN);
first information indicating whether Hybrid Automatic Repeat Request (HARQ) feedback is disabled for the CG PUSCH; and
second information indicating a timing offset for the CG PUSCH;
transmitting circuitry configured to transmit the CG PUSCH based on the configuration for the CG PUSCH and the second information; and
a processor configured to flush a data buffer of the CG PUSCH immediately after transmitting the CG PUSCH, without waiting for a HARQ-acknowledgement (HARQ-ACK) and a potential retransmission of the CG PUSCH, in a case that the first information indicates that the HARQ feedback is disabled for the CG PUSCH.
2 . A Base Station (gNB), comprising:
transmitting circuitry configured to transmit:
a configuration for a configured grant (CG) physical uplink shared channel (PUSCH) in a non-terrestrial network (NTN);
first information indicating whether Hybrid Automatic Repeat Request (HARQ) feedback is disabled for the CG PUSCH; and
second information indicating a timing offset for the CG PUSCH;
receiving circuitry configured to receive the CG PUSCH based on the configuration for the CG PUSCH and the second information; and
the transmitting circuitry configured to not transmit a scheduling downlink control information (DCI) for a retransmission of the CG PUSCH based immediately after receiving the CG PUSCH, without sending a HARQ-acknowledgement (HARQ-ACK) and a potential retransmission of the CG PUSCH, in a case that the first information indicates that the HARQ feedback is disabled for the CG PUSCH.
3 . A method by a User Equipment (UE), comprising:
receiving a configuration for a configured grant (CG) physical uplink shared channel (PUSCH) in a non-terrestrial network (NTN);
receiving first information indicating whether Hybrid Automatic Repeat Request (HARQ) feedback is disabled for the CG PUSCH;
receiving second information indicating a timing offset for the CG PUSCH;
transmitting the CG PUSCH based on the configuration for the CG PUSCH and the second information; and
flushing a data buffer of the CG PUSCH immediately after transmitting the CG PUSCH, without waiting for a HARQ-acknowledgement (HARQ-ACK) and a potential retransmission of the CG PUSCH, in a case that the first information indicates that the HARQ feedback is disabled for the CG PUSCH.
