Abstract: A communication control method pertaining to an embodiment of the present invention is for controlling dual connectivity communication which uses a master base station that establishes RRC connection with a user terminal and a secondary base station that provides a supplementary wireless resource to the user terminal. The communication control method comprises: a step in which the master base station receives, from the user terminal, a measurement report which includes measurement results found for each cell in the user terminal; and a step in which the secondary base station receives, from the master base station, a supplementary request for requesting the allocation of resources to the user terminal. In the step for receiving a supplementary request, the master base station includes, in the supplementary request, measurement results for a cell of the secondary base station which is included in the measurement results, and transmits the same.

Abstract: UE 100 transmits and receives traffic to and from eNB 200 in a cellular communication system capable of cooperating with a WLAN system. The UE 100 determines, on the basis of a determination parameter related to a situation of the UE 1001, whether or not an offload in which the traffic is transitioned to the WLAN system should be performed, when the UE 100 is selected as a target terminal subject to the offload. The UE 100 transmits, to the eNB 200, a rejection notification that related to rejection to the offload when the UE 100 determines that the offload should not be performed.

Abstract: A method for performing D2D (Device-to-Device) communication, a user terminal for supporting D2D communication, and an apparatus used in a user terminal supporting D2D communication include a user terminal in coverage of a base station broadcasting first control information using a first time radio resource, and a second user terminal being out of coverage of the base station receiving the first control information, selecting, by the second user terminal, a second time radio resource different from the first time radio resource, for transmitting second control information, and transmitting, by the second user terminal, the second control information using the second time radio resource. The second control information is determined based on the first control information, and indicates a frequency band to be used for the D2D communication. The second user terminal performs D2D communication on the basis of the first control information received from the first user terminal.
