Terminal and radio communication method
A terminal according to an aspect of the present disclosure includes: a receiving section that receives information on one or more cells that transmit a downlink control channel for scheduling a physical shared channel of a primary cell; and a control section that determines, based on a cell that transmits the downlink control channel, at least one of a cell that monitors the downlink control channel and a search space type.
1. A terminal comprising:
a receiver that receives information on a scheduling type applied to a primary cell; and
a processor that determines, based on the information on the scheduling type, a cell that transmits a downlink control channel that includes a 3-bit Carrier Indicator Field for scheduling the primary cell, and
wherein when a scheduling type in which scheduling is performed by another secondary cell is configured for the primary cell, the primary cell and the another secondary cell are included in a same frequency range.
2. The terminal according to claim 1 , wherein when the primary cell is configured as a scheduled cell which is scheduled by the another secondary cell, the primary cell is scheduled by at least one of a downlink control channel on the another secondary cell and a downlink control channel on the primary cell.
3. The terminal according to claim 1 , wherein when a scheduling type in which scheduling is performed by the another secondary cell is configured for the primary cell, the primary cell and the another secondary cell are included in a same cell group that is an MCG.
4. A radio communication method for a terminal, comprising:
receiving information on a scheduling type applied to a primary cell; and
determining, based on the information on the scheduling type, a cell that transmits a downlink control channel that includes a 3-bit Carrier Indicator Field for scheduling the primary cell, and
wherein when a scheduling type in which scheduling is performed by another secondary cell is configured for the primary cell, the primary cell and the another secondary cell are included in a same frequency range.
5. A base station comprising:
a transmitter that transmits information on a scheduling type applied to a primary cell; and
a processor that indicates, based on the information on the scheduling type, a cell that transmits a downlink control channel that includes a 3-bit Carrier Indicator Field for scheduling the primary cell, and
wherein when a scheduling type in which scheduling is performed by another secondary cell is configured for the primary cell, the primary cell and the another secondary cell are included in a same frequency range.
6. A system comprising a terminal and a base station, wherein
the terminal comprises:
a receiver that receives information on a scheduling type applied to a primary cell; and
a processor that determines, based on the information on the scheduling type, a cell that transmits a downlink control channel that includes a 3-bit Carrier Indicator Field for scheduling the primary cell,
wherein when a scheduling type in which scheduling is performed by another secondary cell is configured for the primary cell, the primary cell and the another secondary cell are included in a same frequency range, and
the base station comprises:
a transmitter that transmits the information on the scheduling type; and
a processor that indicates, based on the information on the scheduling type, the cell that transmits the downlink control channel.
