Abstract: A UE performs communication with another UE. A UE detects another communication different from the communication. The UE has a predetermined communication resource selection rule stored therein. The UE controls the communication. When the other communication is detected, the UE selects a communication resource based on the stored communication resource selection rule. This allows radio waves to be utilized efficiently.

Abstract: A communication terminal includes a terminal communicator configured to perform radio communication with a base station, and a terminal controller configured to control the terminal communicator. The terminal controller causes the terminal communicator to transmit a first message of the radio communication to the base station without including, in the first message, specific terminal information indicating that the communication terminal is a specific communication terminal use of which is possibly restricted by the base station, receives a second message as a response to the first message from the base station via the terminal communicator, includes the specific terminal information in a subsequent message that is a third message or is a message subsequent to the third message as a response to the second message, and causes the terminal communicator to transmit the subsequent message to the base station.

Abstract: A base station device includes: a communication unit configured to wirelessly communicate with a terminal device; a storage unit; and a control unit. The control unit is configured to refer to discontinuous reception information, stored in the storage unit, which indicates a plurality of discontinuous reception settings, transmit transmission data to the terminal device in at least a portion of a first reception period of time corresponding to at least one of the discontinuous reception settings, and transmit the transmission data to the terminal device in at least a portion of a second reception period of time corresponding to at least another one of the discontinuous reception settings in a case that it is determined that response information with respect to the transmitted transmission data is not received.

Abstract: A UE, which is a mobile terminal, is capable of a device-to-device communication. The UE displays, on a display unit, an LTE antenna picto based on a reception level of a radio wave transmitted by a base station, and a D2D antenna picto based on a reception level of a radio wave transmitted by a UE over the device-to-device communication. According to the UE, the reception level of the radio wave in the device-to-device communication can be immediately confirmed, as well as a reception level of a radio wave in communication with the base station.

Abstract: A communication system is for improving utilization efficiency of radio resources. The communication system includes a base station device and a plurality of terminal devices that communicate with the base station device. The base station device includes a first control unit that assigns radio resources including at least one or more resource blocks to at least one of the plurality of terminal devices. The at least one of the plurality of terminal devices comprises a second control unit that transmits transmission data by using at least some of the radio resources assigned to the at least one of the plurality of terminal devices.

Abstract: A base-station apparatus includes: a communicator that performs wireless communication; and a controller. During communication with at least a first terminal apparatus, when a communication volume used for communication that is newly stated with a second terminal apparatus becomes smaller than or equal to an un-used communication volume, the controller transmits, to a target terminal apparatus that is one of the first and second terminal apparatuses, a communication instruction for communication with a second base-station apparatus having a coverage range in which the target terminal apparatus is located, and when a communication volume used for communication with the target terminal apparatus exceeds the un-used communication volume, the controller transmits a callback instruction for callback from the second base-station apparatus to the base-station apparatus to the target terminal apparatus or the second base-station apparatus.
