Abstract

This user terminal is provided with: a receiving unit which, in order to suitably understand the scheduling timing of data scheduled in a DL control channel, monitors a downlink control channel transmitted in multiple different time regions and/or frequency regions and receives downlink control information (DCI); and a control unit which receives and/or transmits data scheduled by the DCI. The control unit controls the receiving timing and/or the transmission timing of the aforementioned data on the basis of at least the timing included in the DCI.

Claims (6)

1. A terminal comprising: a receiving section that receives a downlink control information and a downlink shared channel that is scheduled by the downlink control information; and a control section that determines an allocation of the downlink shared channel in a time domain based on a first timing indicated by a slot and a second timing indicated by a symbol that are obtained from information notified by the downlink control information, wherein the control section determines a given slot to which the downlink shared channel is scheduled based on a slot in which the downlink control information is transmitted and an offset obtained from the information notified by the downlink control information, and determines a symbol to which the downlink shared channel is allocated based on the information notified by the downlink control information, and wherein the first timing is defined based on a numerology of the downlink shared channel.
2. The terminal according to claim 1, wherein the control section determines, using a start of the given slot as a reference timing, the symbol to which the downlink shared channel is allocated based on the information notified by the downlink control information.
3. A terminal comprising: a receiving section that receives a downlink control information that is used for scheduling an uplink shared channel; and a control section that determines an allocation of the uplink shared channel in a time domain based on a first timing indicated by a slot and a second timing indicated by a symbol that are obtained from information notified by the downlink control information, wherein the control section determines a given slot to which the uplink shared channel is scheduled based on a slot in which the downlink control information is transmitted and an offset obtained from the information notified by the downlink control information, and determines a symbol to which the uplink shared channel is allocated based on the information notified by the downlink control information, wherein the first timing is defined based on a numerology of the uplink shared channel.
4. The terminal according to claim 3, wherein the control section determines, using a start of the given slot as a reference timing, the symbol to which the uplink shared channel is allocated based on the information notified by the downlink control information.
5. A radio communication method comprising: receiving a downlink control information and a downlink shared channel that is scheduled by the downlink control information; and determining an allocation of the downlink shared channel in a time domain based on a first timing indicated by a slot and a second timing indicated by a symbol that are obtained from information notified by the downlink control information, wherein the determining an allocation determines a given slot to which the downlink shared channel is scheduled based on a slot in which the downlink control information is transmitted and an offset obtained from the information notified by the downlink control information, and determines a symbol to which the downlink shared channel is allocated based on the information notified by the downlink control information, and wherein the first timing is defined based on a numerology of the downlink shared channel.
6. A radio base station comprising: a transmitting section that transmits a downlink control information and a downlink shared channel that is scheduled by the downlink control information; and a control section that controls an allocation of the downlink shared channel in a time domain based on a first timing indicated by a slot and a second timing indicated by a symbol that are obtained from information notified by the downlink control information, wherein the control section determines a given slot to which the downlink shared channel is scheduled based on a slot in which the downlink control information is transmitted and an offset obtained from the information notified by the downlink control information, and allocates the downlink shared channel based on the information notified by the downlink control information, and wherein the first timing is defined based on a numerology of the downlink shared channel.
