Abstract
A user terminal according to an aspect of the present disclosure includes a receiving section that receives downlink control information (DCI) indicating transmission of an uplink shared channel, and a control section that determines that a size of a time domain resource allocation (RA) field included in the DCI is different depending on a format of the DCI to control the transmission of the uplink shared channel based on the field. According to one aspect of the present disclosure, the number of candidates of the PUSCH time domain RA can be appropriately controlled.
Claims5
A terminal comprising:
- a receiving section that receives information used for scheduling of a physical uplink shared channel (PUSCH);
- and
- a processor that, when the information comprises downlink control information (DCI) format 0_0 received in a User Equipment(UE)-specific search space or when the information comprises DCI format 0_0 received in a common search space and having a Cyclic Redundancy Check (CRC) scrambled by Cell-Radio Network Temporary Identifier (C-RNTI), controls transmission of the PUSCH by determining, based on a field in the DCI format 0 0 that indicates an index of a time domain resource allocation list referenced for DCI format 0 _1,an entry included in the time domain resource allocation list.
A radio communication method for a terminal, comprising:
- receiving information used for scheduling of a physical uplink shared channel (PUSCH);
- and
- when the information comprises downlink control information (DCI) format 0_0 received in a User Equipment(UE)-specific search space or when the information comprises DCI format 0_0 received in a common search space and having a Cyclic Redundancy Check (CRC) scrambled by Cell-Radio Network Temporary Identifier (C-RNTI), controlling transmission of the PUSCH by determining, based on a field in the DCI format 0_0 that indicates an index of a time domain resource allocation list referenced for DCI format 0_1, an entry included in the time domain resource allocation list.
A base station comprising:
- a transmitter that transmits information used for scheduling of a physical uplink shared channel (PUSCH) to a terminal;
- and
- a receiver that, when the information comprises downlink control information (DCI) format 0_0 transmitted in a User Equipment(UE)-specific search space or when the information comprises DCI format 0_0 transmitted in a common search space and having a Cyclic Redundancy Check (CRC) scrambled by Cell-Radio Network Temporary Identifier (C-RNTI), receives the PUSCH based on an index of a time domain resource allocation list referenced for DCI format 0_1, the index being indicated by a field in the DCI format 0_0.
A system comprising:
- a terminal that comprises:
- a receiver that receives information used for scheduling of a physical uplink shared channel (PUSCH);
- and
- a processor that, when the information comprises downlink control information (DCI) format 0_0 received in a User Equipment(UE)-specific search space or when the information comprises DCI format 0_0 received in a common search space and having a Cyclic Redundancy Check (CRC) scrambled by Cell-Radio Network Temporary Identifier (C-RNTI), controls transmission of the PUSCH a by determining, based on a field in the DCI format 0_0 that indicates an index of a time domain resource allocation list referenced for DCI format 0_1, an entry included in the time domain resource allocation list;
- and
- a base station that comprises:
- a transmitter that transmits the information to the terminal;
- and
- a receiver receives the PUSCH.
