    摘要： When terminal identification information TI of one terminal device used by a user among two or more terminal devices is newly stored in a memory of a host device together with user identification information UI (S3a), an examination part examines, in the memory of the host device, a presence or absence of terminal identification information (terminal identification information TI-p) corresponding to the user identification information UI, excluding terminal identification information TI and terminal identification information corresponding to a terminal device that is currently used by the user (S11). When the terminal identification information TI-p exists, a management part performs control to transmit predetermined instruction information together with the terminal identification information TI-p to the two or more terminal devices (S12). When the terminal identification information TI-p received together with the instruction information from the host device matches own terminal identification information, an information erasure part erases information on a user other than the user who is currently stored in own memory (S13).

    摘要： A terminal according to one aspect of the present disclosure includes: a transmitting section that transmits capability information indicating support of update of at least part of radio resource control (RRC) parameters between a serving cell and a non-serving cell; and a control section that assumes, when the capability information is transmitted, different cell radio network identifiers (C-RNTIs) in the serving cell and the non-serving cell. According to one aspect of the present disclosure, a C-RNTI can be appropriately selected.

    摘要： In 5G cell (230) of 5G system (200), upon detecting that access to the 5G system (200) is barred, the 5G system (200) is congested, 5G core network (220) of the 5G system (200) does not support IMS-type communication service, or fallback to 4G system (300) is instructed, UE (100) selects 4G cell (330) of the 4G system (300) as a target cell for connection. The UE (100) transmits a connection request signal for the IMS-type communication service to the target cell for connection.

    摘要： A terminal according to one aspect of the present disclosure includes: a control section that determines a first resource for interference measurement corresponding to a first transmission/reception point or a second resource for interference measurement corresponding to a second transmission/reception point, based on at least one of a first resource for channel measurement corresponding to the first transmission/reception point and a second resource for channel measurement corresponding to the second transmission/reception point; and a transmitting section that transmits a channel state information report, based on the first resource for interference measurement and the second resource for interference measurement. According to one aspect of the present disclosure, it is possible to appropriately perform measurement and report of CSI for multi-panel/TRP.

    摘要： A terminal according to one aspect of the present disclosure includes: a control section that determines a power control parameter for a physical uplink shared channel (PUSCH), based on reception of a medium access control control element (MAC CE); and a transmitting section that transmits the PUSCH by using transmission power based on the power control parameter. According to one aspect of the present disclosure, a parameter for transmission power control can be appropriately determined.
