Abstract: A radio terminal according to one embodiment transmits data of one bearer to two radio communication apparatuses. The radio terminal comprises a controller configured to transmit a buffer status report to only one of the two radio communication apparatuses, if a data amount accumulated in a predetermined buffer falls below a threshold value and only the one radio communication apparatus is designated as a transmission target of the buffer status report. The controller is configured to change the transmission target of the buffer status report from the one radio communication apparatus to the other radio communication apparatus, if the data amount falls below the threshold value and a failure in a radio link with the one radio communication apparatus is detected.

Abstract: A user terminal is used in a mobile communication system configured to support Device to Device (D2D) communication that is direct device-to-device communication. The user terminal comprises a controller. The controller is configured to, if determining to execute a D2D discovery procedure targeted to a user terminal out of a cell coverage, execute the D2D discovery procedure by using a D2D data resource in a pre-configured resource pool for D2D communication. The controller is configured to execute, upon executing the D2D discovery procedure, a process of transmitting identification information indicating that data carried by the D2D data resource is used for the D2D discovery procedure.

Abstract: In a communication control method according to a present embodiment, at least one radio terminal of a first radio terminal and a second radio terminal discoveries the other radio terminal by executing a discovery for discovering a proximal terminal. The at least one radio terminal reports, to a network apparatus that the other radio terminal is discovered. The network apparatus requests, while the first radio terminal is located within a coverage of a cell, at least one of the first radio terminal and the second radio terminal to make a preparation for executing a relay by the second radio terminal by utilizing a proximal service.

Abstract: A user terminal according to an embodiment comprises: a controller configured to perform control to discard data of a predetermined sequence number, under a predetermined condition based on a window size used in a receiving RLC entity to define a sequence number of data capable of being received without advancing a window, in the receiving RLC entity established to receive data by D2D communication that is direct device-to-device communication. The controller sets the window size to zero.

Abstract: In the communication control method according to the present embodiment, a user terminal receives a scheduling assignment indicating a location of a radio resource used in a reception of communication data by direct device-to-device communication. The user terminal decides a terminal identifier that is different from a terminal identifier indicating another user terminal included in the scheduling assignment, as a terminal identifier indicating the user terminal. The user terminal transmits a scheduling assignment including the decided terminal identifier.

Abstract: A communication control method is a method for performing offload to transfer a traffic load of a cellular base station to an access point. The communication control method comprises a step of maintaining without releasing the first connection, by a user terminal that have established a first connection with the cellular base station, even when the offload is started after establishing a second connection with the access point; and a determining step of determining, by the user terminal, whether the offload is continued or canceled after the offload is started.
