    Abstract: A user equipment, apparatus, and base station include a processor and a memory. The processor user equipment and apparatus is configured to receive, from a base station, a radio network temporary identifier for direct communication. The processor is further configured to receive, from the base station, resource information transmitted by use of the radio network temporary identifier. The received resource information indicates a radio resource to be used for the user equipment to perform the direct communication. The processor of the base station is configured to transmit, to a user equipment, a radio network temporary identifier for direct communication. The base station processor is further configured to transmit, to the user equipment, resource information transmitted by use of the radio network temporary identifier. The transmitted resource information indicates a radio resource to be used for the user equipment to perform the direct communication.

    Abstract: A radio terminal according to one embodiment comprises: a controller configured to detect a radio problem in communication with a base station in an RRC connected state and attempt a recovery from the radio problem; and a transmitter configured to transmit, to the base station, a polling signal for confirming whether or not the base station considers an RRC state of the radio terminal as the RRC connected state in response to the successful recovery. The controller maintains the RRC connected state in response to reception, from the base station, of a response signal to the polling signal.

    Abstract: A radio terminal according to one embodiment is configured to perform a relay between another radio terminal and a network. The radio terminal comprises: a transmitter configured to notify the network of first information indicating that the radio terminal is a relay terminal of the another radio terminal; a controller configured to forward data addressed to the another radio terminal to the another radio terminal via a connection between the another radio terminal through the radio terminal and the network; and a receiver configured to receive from the network a message indicating that the data addressed to the another radio terminal exists when at least part of the connection is released. The controller is configured to start control for establishing the connection in order to forward the data addressed to the another radio terminal in response to receiving the message.

    Abstract: A communication device according to one embodiment includes a controller and a transmitter. The controller is configured to identify a zone that is a geographical section where the communication device is located, and select a predetermined transmission resource region from a plurality of transmission resource regions included in one transmission resource pool associated with the identified zone. The transmitter is configured to transmit a direct radio signal to another communication device by using a resource in the predetermined transmission resource region.
