Abstract: A communication control method, user equipment and apparatus thereof include transmitting, to a base station by a user equipment, first information on a priority of a data pack to be transmitted from the user equipment via direct communication in which the data packet is transmitted to another user equipment without passing through the base station. The first information assists the base station in scheduling transmission resources for the direct communication. The method, user equipment and apparatus also include transmitting a request for requesting transmission resources for the direct communication to the base station by the user equipment, and receiving by the user equipment from the base station second information indicating transmission resources for the direct communication scheduled by the base station.

Abstract: A base station allocates radio resources used for device-to-device D2D communication based on location information indicating a geographical location of a user terminal located in a cell of a base station. The base station notifies the allocated radio resources to the user terminal by a unicast manner, and the user terminal uses the allocated radio resources to transmit a signal for the D2D communication.

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 according to one embodiment, a base station in a LTE system transmits to a user equipment, configuration information configuring an LTE-WLAN Aggregation (LWA) bearer using both radio resources of the LTE system and radio resource of a WLAN system. The configuration information includes first information indicating a threshold value for an amount of data. The user equipment configures the LWA bearer based on the configuration information. The user equipment transmits, in response to an amount of data belonging to the LWA bearer being equal to or more than the threshold value, the data by using the radio resources of both the LTE system and the WLAN system. The user equipment transmits, in response to the amount of data belonging to the LWA bearer being below the threshold value, the data by using the radio resource of either the LTE system or the WLAN system.

Abstract: A UE (100) receives a handover command from a source cell to perform a handover to a target cell in response to the handover command. The handover command includes a notification indicating omitting a random access procedure during the handover. The UE (100) omits, in response to the notification, the random access procedure during the handover.

Abstract: A communication control method, and network apparatus includes receiving a PLMN identifier and a first identifier from a first user terminal, where the first identifier is included in a discovery signal which the first user terminal has received from a second user terminal, determining, in response to receiving the first identifier, whether the first identifier is an identifier allocated in the first PLMN. In response to a determination that the first identifier is not the identifier allocated in the first PLMN, sending the first identifier to a second network apparatus belonging to a second PLMN, and receiving the information of an application used by the second user terminal, from the second network apparatus. In response to the controller determining that the first identifier is the identifier allocated in the first PLMN, transmitting, to the first user terminal, information of the application used by the second user terminal.
