Terminal and radio communication method
A terminal according to an aspect of the present disclosure includes a transmitting section that transmits a configured grant-based uplink shared channel, a receiving section that receives downlink control information which indicates retransmission of the uplink shared channel, and a control section that controls the retransmission based on a priority configured for the retransmission of the uplink shared channel.
1. A terminal comprising:
a transmitter that transmits a physical uplink shared channel (PUSCH) with configured grant;
a receiver that receives downlink control information (DCI) indicating retransmission of the PUSCH with configured grant; and
a processor that controls the retransmission of the PUSCH with configured grant, based on priorities that are independently configured for the transmission of the PUSCH with configured grant and the retransmission of the PUSCH with configured grant,
wherein the priority configured for the transmission of PUSCH with configured grant is configured by radio resource control (RRC) signaling,
wherein the processor determines, based on bit information included in the DCI, the priority configured for the retransmission of the PUSCH with configured grant, the DCI being DCI format 0_2, and
wherein, when the bit information is not included in the DCI format 0_2, lower priority is configured for the retransmission of the PUSCH with configured grant.
2. A radio communication method for a terminal, comprising:
transmitting a physical uplink shared channel (PUSCH) with configured grant;
receiving downlink control information (DCI) indicating retransmission of the PUSCH with configured grant; and
controlling the retransmission of the PUSCH with configured grant, based on priorities that are independently configured for the transmission of the PUSCH with configured grant and the retransmission of the PUSCH with configured grant,
wherein the priority configured for the transmission of PUSCH with configured grant is configured by radio resource control (RRC) signaling,
determining, based on bit information included in the DCI, the priority configured for the retransmission of the PUSCH with configured grant, the DCI being DCI format 0_2, and
wherein, when the bit information is not included in the DCI format 0_2, lower priority is configured for the retransmission of the PUSCH with configured grant.
3. A base station comprising:
a processor that configures transmission of a physical uplink shared channel (PUSCH) with configured grant; and
a transmitter that transmits downlink control information (DCI) indicating retransmission of the PUSCH with configured grant,
wherein the processor configures priorities independently for the transmission of the PUSCH with configured grant and the retransmission of the PUSCH with configured grant, and controls the retransmission of the PUSCH with configured grant,
wherein the priority configured for the transmission of PUSCH with configured grant is configured by radio resource control (RRC) signaling,
wherein the processor configures, by using bit information included in the DCI, the priority for the retransmission of the PUSCH with configured grant, the DCI being DCI format 0_2, and
wherein, when the bit information is not included in the DCI format 0_2, lower priority is configured for the retransmission of the PUSCH with configured grant.
4. A system comprising a terminal and a base station, wherein
the terminal comprises:
a transmitter that transmits a physical uplink shared channel (PUSCH) with configured grant;
a receiver that receives downlink control information (DCI) indicating retransmission of the PUSCH with configured grant; and
a processor that controls the retransmission of the PUSCH with configured grant, based on priorities that are independently configured for the transmission of the PUSCH with configured grant and the retransmission of the PUSCH with configured grant,
wherein the priority configured for the transmission of PUSCH with configured grant is configured by radio resource control (RRC) signaling, and
wherein the processor determines, based on bit information included in the DCI, the priority configured for the retransmission of the PUSCH with configured grant, the DCI being DCI format 0_2, and
the base station comprises:
a processor that configures the transmission of the PUSCH with configured grant; and
a transmitter that transmits the DCI,
wherein the processor configures the priorities independently for the transmission of the PUSCH with configured grant and the retransmission of the PUSCH with configured grant, and controls the retransmission of the PUSCH with configured grant,
wherein the processor configures, by using the bit information, the priority for the retransmission of the PUSCH with configured grant, and
wherein, when the bit information is not included in the DCI format 0_2, lower priority is configured for the retransmission of the PUSCH with configured grant.
