The step of performing the reselection of the target cell comprises: a first reselection step of performing, by the user terminal, the reselection of the target cell in a response to reception of a paging signal for requesting the reselection of the target cell from a current serving cell; and a second reselection step of performing, by the user terminal, the reselection of the target cell in a response to a trigger without dependence on the paging signal. In the first reselection step, the user terminal starts measurement of a quality of a measurement target frequency included in system information broadcast from the current serving cell, in response to the reception of the paging signal.
Abstract: A relay node according to one embodiment comprises a controller configured to establish a connection with a radio terminal and to establish a connection with a base station; a receiver configured to receive information of the radio terminal from the base station; and a transmitter configured to transmit the information to the radio terminal. The receiver receives delivery acknowledgement information from the radio terminal before the information is transmitted. The delivery acknowledgement information indicates that the radio terminal has received the information. The transmitter stops transmitting the information to the radio terminal in response to reception of the delivery acknowledgement information.
Abstract: In a communication method, a base station provides a specific resource pool available only between short-range devices, of resource pools available between devices in a sidelink. A first communication device executes, at least one of transmission and reception of a sidelink signal to and from a second communication device that is a short-range communication device, by using the specific resource pool.
Abstract: A mobile communication method starts, at a user equipment, a discontinuous reception (DRX) operation with a DRX cycle having an On duration in which a downlink signal transmitted from a radio base station is to be monitored and an Off duration other than the On duration in a radio resource control (RRC) connected state where a RRC connection is established between the user equipment and the radio base station. The method determines, at the user equipment, a first DRX cycle to be configured to the user equipment. The Off duration of the first DRX cycle is greater than that of a second DRX cycle currently configured to the user terminal. The method transmits, from the user equipment to the radio base station, first information indicating the first DRX cycle, and the radio base station uses the first information to configure parameters for the RRC connected state to the user equipment.
