Abstract: A user terminal according an embodiment, comprises: a controller configured to execute measurement based on a radio signal in a secondary cell in an unlicensed band; and a transmitter configured to transmit, to a base station, a report of measurement results based on the radio signal. The controller is configured to determine whether or not identification information to which a predetermined scramble is applied is detected from a predetermined radio signal in the secondary cell. The transmitter is configured to transmit, to the base station, the report of measurement results not including a predetermined measurement result based on the predetermined radio signal, in response to no detection of the identification information from the predetermined radio signal.

Abstract: A user terminal, user terminal chipset, and method including receiving, from a cellular base station included in a cellular radio access network (RAN), parameters for an offload from the cellular RAN to a wireless local area network (LAN), and performs an access network selection between the cellular RAN and the wireless LAN based on the parameters. Parameters include a first threshold to be compared with a cellular signal strength of the cellular RAN, a second threshold to be compared with a wireless LAN signal strength of the wireless LAN, and a third threshold to be compared with a load of the wireless LAN. Performing the access network selection includes selecting the wireless LAN 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 being lower than the third threshold.

Abstract: A base station performs radio communication with a plurality of terminals in a specific frequency band in which frequency sharing among a plurality of communication operators and a plurality of radio communication systems is permitted. Part of a frequency region within the specific frequency band is set as a control-only region. The base station determines, by the carrier-sense in the specific frequency band, a data region for user data transmission, from a frequency region different from the part of the frequency region within the specific frequency band. The base station transmits or receives, in a control region R1, terminal-specific data control information for individually controlling a user data transmission of each terminal within the data region.

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.
