Abstract: UE 100 receives, when a connection with eNB 200 is established by the UE 100, from the eNB 200, preamble information indicating a random access preamble to be used in a random access procedure when establishing again a connection with the eNB 200. The UE 100 holds, without discarding, the preamble information even when the UE 100 establishes a connection with AP 300 and releases the connection with the eNB 200.

Abstract: A radio terminal UE according to one embodiment includes a radio communication unit 210 configured to receive a plurality of parameters including a first parameter for high-speed movement and a second parameter for non-high-speed movement as parameters for processing for switching to a neighboring base station from a base station connected to the radio terminal, and a controller 260 configured to acquire movement speed information indicating a movement speed of the radio terminal and to select a parameter corresponding to the movement speed information. The first parameter is configured to inhibit processing for switching to a Pico base station PeNB which is included in the neighboring base stations.

Abstract: A user terminal includes: a controller configured to perform, in accordance with one selection rule of a first selection rule and a second selection rule, as a selection rule applied to a cell reselection in an idle mode. The first selection rule is a selection rule for selecting an appropriate cell irrespective of whether the user terminal has an interest in a D2D proximity service. The second selection rule is a selection rule for preferentially selecting, as an appropriate cell, a cell belonging to a frequency available for the D2D proximity service, in case that the user terminal has the interest in the D2D proximity service. The controller applies, in accordance with configuration, the second selection rule instead of the first selection.

Abstract: A user terminal includes processor configured to execute a process of receiving, from a serving cell, broadcast information on a device-to-device (D2D) discovery, a procedure used by the user terminal to discover a proximal user terminal. The broadcast information includes a cell identifier of a neighbor cell, and synchronization information on the neighbor cell. The synchronization information includes a first value or a second value. The processor executes processes of: receiving both a D2D synchronization signal and a D2D discovery signal that are transmitted by a proximal user terminal in the neighbor cell in response to the synchronization information including the first value; and receiving the D2D discovery signal without receiving the D2D synchronization signal in response to the synchronization information including the second value.

Abstract: A communication method according to one embodiment comprises the steps of transmitting capability of a radio terminal, which is a pedestrian user equipment (UE), from the radio terminal to a base station, receiving, by the base station, the capability of the radio terminal from the radio terminal, and individually transmitting, from the base station to the radio terminal, information of a radio resource pool for direct terminal-to-terminal communication based on the capability of the radio terminal. The information of the radio resource pool is information of a resource pool based on a geographical zone.
