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 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 user terminal and method thereof transmit a notification to a base station before starting direct device to device (D2D) communication, where the notification indicates a desire for performing the D2D communication, transmitting to the base station a measurement report including results of measurement of a cell reference signal, transmitting to the base station a data amount notification indicating an amount of data to be transmitted from the first user terminal to a second user terminal, and using radio resources allocated from the base station, where the radio resources are used by the first user terminal to transmit the data to the second user terminal. A base station operates to receive the above notifications and measurement report from the user terminal and allocate radio resources used by the user terminal to transmit the data to the second user terminal.
