Abstract: A user terminal transmits and/or receives downlink traffic through cellular/WLAN aggregation by using a first communication and a second communication. The downlink traffic is divided into traffic for cellular communication network and traffic for WLAN. The user terminal further transmits an uplink control signal through the cellular/WLAN aggregation by using the first communication and without using the second communication. The user terminal further notifies the base station of a report regarding the second communication by the first communication. The report indicates a radio link failure in the second communication and includes a reason for the radio link failure. The reason includes a first reason and a second reason. The first reason relates to a radio environment in the second communication. The second reason does not relate to the radio environment.

Abstract: A network apparatus according to the present invention comprises: a receiver configured to receive, from a user terminal, channel state information corresponding to a channel state of a downlink signal from a cell to which the user terminal is connected, to the user terminal; a controller configured to determine transmission frequency of the channel state information; and a transmitter configured to transmit, to the user terminal, frequency information indicating the transmission frequency determined by the controller. The controller determines the transmission frequency of the user terminal on the basis of fixation information indicating that the user terminal is a fixed user terminal whose movement is restricted.

Abstract: A mobile communication system according to the embodiment supports cellular communication in which a data path passes through a network and D2D communication that is direct device-to-device communication in which a data path does not pass through the network. A frequency division multiplexing scheme is applied to the cellular communication and a code division multiplexing scheme is applied to the D2D communication. The network assigns a spread code having orthogonality to a user terminal in response to a request from the user terminal. The user terminal performs the D2D communication by using the spread code assigned by the network.

Abstract: A communication control method used for D2D communication that is direct inter-terminal communication performed by using a radio resource assigned from a base station, comprises a step A of securing, by a user terminal, a logical channel group for the D2D communication; a step B of notifying, by the user terminal, the base station of the logical channel group secured in the step A; and a step C of assigning, by the base station, a radio network temporary identifier for the D2D communication to the logical channel group notified in the step B.

Abstract: UE 100 transmits and receives traffic to and from eNB 200 in a cellular communication system capable of cooperating with a WLAN system. The UE 100 determines, on the basis of a determination parameter related to a situation of the UE 1001, whether or not an offload in which the traffic is transitioned to the WLAN system should be performed, when the UE 100 is selected as a target terminal subject to the offload. The UE 100 transmits, to the eNB 200, a rejection notification that related to rejection to the offload when the UE 100 determines that the offload should not be performed.

Abstract: A communication control method comprises: transmitting, by a user terminal to a base station, a message including information notifying the base station of the user terminal having an interest in receiving a discovery signal in a discovery procedure for discovering a proximal terminal, and information of a frequency in the discovery procedure, when the user terminal has an interest in the discovery procedure. The user terminal notifies the base station of a request for a gap for receiving the discovery signal.
