Abstract: User equipment, an apparatus configured to control user equipment, and a method. The method may include receiving by a user equipment from a base station, a synchronization signal and a master information block, the master information block transmitted at a same transmission cycle as a transmission cycle of the synchronization signal. The method may further include receiving by the user equipment from the base station, first information indicating time domain positions at which the synchronization signal and the master information block are to be transmitted. In addition, the method may include receiving by the user equipment from the base station, second information indicating a periodicity of transmission of the synchronization signal and the master information block. The periodicity indicated by the second information may be different from 40 ms.

Abstract: A user equipment, method, and chipset receive system information block (SIB) broadcasted from a base station, and while the user equipment is in a radio resource control (RRC) idle mode in which no RRC connection is established between the use equipment and the base station, the SIB is used to control the D2D communication. Data is transmitted to other user equipment by the D2D communication based on the SIB while the user equipment is in the RRC idle mode. The SIB includes resource information indicating usable radio resources for the D2D communication and power information used for controlling transmission power in the D2D communication. The transmitting comprises determinations of radio resources used to transmit the data based on the resource information and transmission power used in transmitting the data based on the power information, and transmitting the data using the determined radio resources and the determined transmission power.

Abstract: A base station according to an embodiment is a base station included in a RAN of a mobile communication system. The base station includes a receiver configured to receive, from a radio terminal in a specific state, a message indicating that the radio terminal has left a RAN paging area, and a transmitter configured to transmit, to a mobility management entity, paging area information related to update of the RAN paging area in response to the reception of the message. The specific state is a state in which an anchor base station in the RAN paging area maintains an S1 connection for the radio terminal and the RAN paging area is configured to the radio terminal.

Abstract: A base station and method thereof includes transmitting from the base station to a user equipment, parameters for an offload from the cellular RAN to a wireless local area network (LAN). The parameters are used by the user equipment to perform an access network selection between the cellular RAN and the wireless LAN, and include a first threshold for comparison with a cellular signal strength of the cellular RAN, a second threshold for comparison with a wireless LAN signal strength of the wireless LAN, and a third threshold for comparison with a load of the wireless LAN. When performing access network selection, the parameters may cause the user equipment to perform the offload, in response to the cellular signal strength being lower than the first threshold, the wireless LAN signal strength being higher than the second threshold, and the load of the wireless LAN being lower than the third threshold.

Abstract: A base station according to one embodiment comprises a controller configured to perform a downlink transmission process using a subframe. The subframe comprises a main PDCCH (Physical Downlink Control Channel) region located at a head portion of the subframe, and a data region other than the main PDCCH region. The data region comprises a short TTI region to which a short TTI (Transmission Time Interval) having a shorter time length than the subframe is applied. The short TTI region comprises a sub-PDCCH region. The controller is configured to arrange information indicating the sub-PDCCH region in the main PDCCH region.
