Abstract: In the communication control method according to the present embodiment, a user terminal transmits a scheduling assignment indicating the location of a radio resource used in a reception of communication data by direct device-to-device communication. The user terminal transmits the communication data including initial transmission data and retransmission data by using the radio resource. The retransmission data is transmitted depending on the number of times of re-transmissions associated with a predetermined scheduling assignment by using a predetermined radio resource of which the location is indicated by the predetermined scheduling assignment.

Abstract: A user terminal transmits and/or receives downlink traffic through cellular/WLAN aggregation by using a first communication and a second communication. The downlink traffic is divided into traffic for cellular communication network and traffic for WLAN. The user terminal further transmits an uplink control signal through the cellular/WLAN aggregation by using the first communication and without using the second communication. The user terminal further notifies the base station of a report regarding the second communication by the first communication. The report indicates a radio link failure in the second communication and includes a reason for the radio link failure. The reason includes a first reason and a second reason. The first reason relates to a radio environment in the second communication. The second reason does not relate to the radio environment.

Abstract: D2D communication is appropriately controlled even in an environment in which a user terminal inside the coverage and a user terminal outside the coverage both exist. A method includes: a step of receiving, by UE 100-1 included in a plurality of UEs 100, from UE 100-n included in the plurality of UEs 100, information related to the UE 100-n; and a step of selecting, by the UE 100-1, a control user terminal for controlling D2D communication, based on the information related to the UE 100-n, from among the plurality of UEs 100.

Abstract: A user equipment, apparatus provided in a user equipment, and method are for receiving a Multicast Broadcast Service, and include receiving a system information block (SIB) from a current serving cell of the user equipment, and performing a cell reselection operation where a cell having a highest ranking determined based on a radio quality and an offset is selected as a serving cell of the user equipment from among a plurality of cells. In the cell reselection operation, a determination is made, based on the SIB, whether to use an infinite offset as the offset to be applied to a cell providing the Multicast Broadcast Service.

Abstract: A user equipment, method, and chipset use a first formula to determine a paging frame which is a radio frame including a paging occasion for the user equipment after the user equipment is configured with an idle mode extended DRX (Discontinuous Reception) cycle, a second formula to determine a subframe from among the paging frame, as the paging occasion, and a third formula to determine a paging hyper-frame. DRX parameters are applied to the first formula and the second formula, but not to the third formula. An idle mode extended DRX cycle is applied to the third formula, which is represented by H-SFN mod TeDRX=α mod TeDRX, where the H-SFN represents a hyper-frame number of the paging hyper-frame, the TeDRX represents the number of the hyper-frames corresponding to the idle mode extended DRX cycle, and the α represents a value specific to the user equipment.
