Abstract
A user equipment (UE) is described. The UE includes receiving circuitry configured to receive signaling that comprises a configuration for a configured grant physical uplink shared channel (PUSCH) or a grant-based PUSCH. The UE also includes a higher layer processor configured to determine whether to use multi-segment transmissions and mini-slot repetitions for the configured grant PUSCH or grant-based PUSCH. The UE further includes transmitting circuitry configured to transmit the multi-segment transmissions and the mini-slot repetitions for the configured grant PUSCH or grant-based PUSCH.
Claims4
A user equipment (UE) that communicates with a base station comprising:
- receiving circuitry configured to:
- receive a Radio Resource Control (RRC) message including first information indicating a repetition type for configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission(s),
- receive a RRC message including second information indicating a repetition type for grant based (GB) PUSCH transmission(s),
- transmitting circuitry configured to:
- perform the CG PUSCH transmission(s) based on the first information,
- perform, based on a detection of a physical downlink control channel (PDCCH) with Cyclic Redundancy Check (CRC) scrambled by Cell Radio Network Temporary Identifier (C-RNTI), the GB PUSCH transmission(s) based on the second information,
- perform, based on a detection of a PDCCH with CRC scrambled by Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) with New Data Indicator (NDI)=1, a retransmission(s) of the CG PUSCH transmission(s) based on the second information.
A base station apparatus that communicates with a user equipment (UE) comprising:
- transmitting circuitry configured to:
- transmit a Radio Resource Control (RRC) message including first information indicating a repetition type for configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission(s),
- transmit a RRC message including second information indicating a repetition type for grant based (GB) PUSCH transmission(s),
- receiving circuitry configured to:
- receive the CG PUSCH transmission(s) based on the first information,
- receive, based on a transmission of a physical downlink control channel (PDCCH) with Cyclic Redundancy Check (CRC) scrambled by Cell Radio Network Temporary Identifier (C-RNTI), the GB PUSCH transmission(s) based on the second information,
- receive, based on a transmission of a PDCCH with CRC scrambled by Configured Scheduling Radio Network Temporary Identifier (CS-RNTI) with New Data Indicator (NDI)=1, a retransmission(s) of the CG PUSCH transmission(s) based on the second information.
