A terminal according to one aspect of the present disclosure includes: a receiving section that receives a configuration related to monitor result reporting of a model; and a control section that controls the monitor result reporting. The control section controls timing of the monitor result reporting or channel state information (CSI) reporting, based on information associated with the monitor result reporting and the CSI reporting. According to one aspect of the present disclosure, it is possible to achieve appropriate overhead reduction/channel estimation/resource use.

A terminal including: a receiving unit configured to receive configuration information from a base station, the configuration information relating to reception of downlink control information and including configurations that vary depending on at least one of a terminal type, a terminal identifier, or a terminal capability; and a control unit configured to set, based on the configuration information, configurations that relate to the reception of the downlink control information and that correspond to the terminal, and, in this terminal, the receiving unit is configured to receive the downlink control information from the base station.

A terminal according to an aspect of the present disclosure includes: a transmitting section that transmits a potential cell switch command indicating there is a possibility for cell switch to be performed; and a control section that switches a serving cell to a target cell indicated in the potential cell switch command. An aspect of the present disclosure enables cell switch to be appropriately performed.

A terminal according to one aspect of the present disclosure includes a receiving section that receives information related to transmission power for a channel or signal for sensing, and a control section that determines the transmission power, based on the information related to the transmission power. According to one aspect of the present disclosure, it is possible to perform appropriate sensing and communication.

A terminal executes a configuration using a radio resource for a high priority terminal for which a specific communication quality is guaranteed in a mobile communication network, the radio resource being distinguished from that for a low priority terminal for which the specific communication quality is not guaranteed, and executes a radio communication using the radio resource.

A terminal includes: a reception unit configured to receive a plurality of TA (Timing Advance) commands corresponding to a plurality of MNOs (Mobile network operators) that perform frequency band sharing; a transmission unit configured to transmit, to a base station of an MNO to which the terminal is connected, TA commands corresponding to MNOs other than the connected MNO; and a control unit configured to perform transmission in the frequency band, based on scheduling received from the base station.

A terminal receives, from a radio base station, guaranteed communication quality information indicating a communication quality which can be guaranteed in a mobile communication network, and assumes, based on the received guaranteed communication quality information, that the communication quality is guaranteed for at least a specific period.

A terminal receives, from a radio base station, acceptance information indicating whether or not a quality guaranteed communication, where a specific communication quality is guaranteed in a mobile communication network, is accepted, and executes a connection with the mobile communication network when the quality guaranteed communication is accepted.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives information related to at least one of a phase difference between a plurality of paths of an optical signal in a base station and path switching of the plurality of paths; and a control section that performs at least one of compensation of the phase difference and measurement of a signal from the base station, based on the information.

A terminal includes: a communication unit configured to communicate with a base station corresponding to a certain MNO (Mobile network operator) among a plurality of MNOs that perform frequency band sharing; and a control unit configured to, in a case where a transmission or reception to or from the base station overlaps with a resource that is unused in order to avoid interference with MNOs of the plurality of MNOs other than the certain MNO, drop or postpone the transmission or reception.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives at least one of first information related to a maximum rank for a first transmission scheme and second information related to a maximum rank for a second transmission scheme, and downlink control information having a field used to indicate association between a phase tracking reference signal (PTRS) and a demodulation reference signal (DMRS); and a control section that judges the number of bits of the field, based on at least one of the first information and the second information when the second transmission scheme is configured.

A terminal receives from a radio base station a guarantee permission indicating that a specific communication quality in a mobile communication network is guaranteed, and assumes, based on the received guarantee permission, that the specific communication quality is guaranteed for at least a specific period.

A terminal executes radio communication with a mobile communication network in a first state in which a specific communication quality in the mobile communication network is guaranteed and the mobile communication network is operating normally, and in a second state in which available radio resources are more limited than in the first state. In the second state, the terminal executes connection with the mobile communication network only when a specific condition is satisfied.

A terminal according to one aspect of the present disclosure includes a receiving section that receives a configuration of a channel state information (CSI)-reference signal (RS) using more than 32 ports, and a control section that measures CSI, based on the configuration. The configuration indicates at least one of a combination of a number of horizontal antenna elements and a number of vertical antenna elements, a number of panels, a combination of the number of panels, the number of horizontal antenna elements, and the number of vertical antenna elements and a combination of a number of horizontal panels, a number of vertical panels, the number of horizontal antenna elements, and the number of vertical antenna elements.
