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.

First claim

What is claimed is:

1. 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 a configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission, the RRC message further including second information indicating a repetition type for a grant based (GB) PUSCH transmission(s); and

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, and
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.

2. A base station apparatus that communicates with a user equipment comprising:
transmitting circuitry configured to:
transmit a Radio Resource Control (RRC) message including first information indicating a repetition type for a configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission, the RRC message further including second information indicating a repetition type for a grant based (GB) PUSCH transmission(s); and

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, and
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 of the CG PUSCH transmission based on the second information.

3. A communication method of a user equipment comprising:
receiving a Radio Resource Control (RRC) message including first information indicating a repetition type for a configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission,
the RRC message further including second information indicating a repetition type for a grant based (GB) PUSCH transmission;
performing the CG PUSCH transmission based on the first information;
performing, 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 based on the second information; and
performing, 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 of the CG PUSCH transmission based on the second information.
