Abstract: A communication method including a base station and user terminal that is configured to communicate by using an unlicensed frequency includes receiving, from the base station, a message including first and second information. The first information is information regarding a configuration for the user terminal to report a measurement result in the unlicensed band, and the second information is information regarding a configuration of carrier aggregation. The method includes the user terminal measuring power in the unlicensed frequency and reporting, to the base station, percentage where the measured power exceeds a threshold value in a measurement period, according to the first information, and communicating with the base station by using the unlicensed frequency as a secondary carrier in the carrier aggregation, according to the second information.

Abstract: A user terminal performs dual connectivity communication with a first base station and a second base station. The user terminal comprises a controller configured to perform a process of transmitting data belonging to a split bearer to the first base station via a first transmission path passing through the first base station and a second transmission path passing through the second base station. The controller is configured to when performing the process of transmitting the data to the first base station, autonomously distribute the data to the first transmission path and the second transmission path without relying on an instruction from the first base station.

Abstract: A base station includes a controller configured to perform connection reestablishment processing on a specific mobile station in response to reception of a connection reestablishment request signal from the specific mobile station from which a radio link failure with another base station has been detected. The controller performs processing of changing a value of a predetermined timer configured to a subordinate mobile station of the base station or the another base station based on information related to a situation of the connection reestablishment processing. The predetermined timer is a timer configured to define a maximum waiting time from transmission of the connection reestablishment request signal to reception of a connection reestablishment response signal in the mobile station.

Abstract: A communication control method according to a first aspect is used in a base station that operates in a power saving mode. The communication control method includes steps of: setting a threshold; receiving an uplink signal transmitted from a user terminal connected to a neighboring base station; and starting a process of transitioning from the power saving mode to a normal mode, in response to that a received power of the uplink signal exceeds the threshold. In the step of setting the threshold, the base station sets the threshold on the basis of information received from the neighboring base station.

Abstract: In a communication method according to one embodiment, a first base station sets a WLAN (Wireless Local Area Network) mobility set that is a set of one or more WLAN identifiers to a user equipment. The first base station decides a handover of the user equipment to a second base station. The first base station includes, in a handover request message for the user equipment, an identifier of a WLAN termination device associated with the one or more WLAN identifiers. The first base station transmits the handover request message including the identifier of the WLAN termination device to the second base station.
