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: 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 radio terminal according to one embodiment transmits data of one bearer to two radio communication apparatuses. The radio terminal comprises a controller configured to transmit a buffer status report to only one of the two radio communication apparatuses, if a data amount accumulated in a predetermined buffer falls below a threshold value and only the one radio communication apparatus is designated as a transmission target of the buffer status report. The controller is configured to change the transmission target of the buffer status report from the one radio communication apparatus to the other radio communication apparatus, if the data amount falls below the threshold value and a failure in a radio link with the one radio communication apparatus is detected.

Abstract: A first base station includes a controller configured to receive capability information from a user terminal for indicating whether a user terminal supports a first architecture using SCG bearer or an second architecture using a split bearer. The SCG bearer goes via both a serving gate way and the secondary base station without going via the first base station. The split bearer goes via both the serving gate way and the first base station and is split in a PDCP layer of the first base station. One split path of the split bearer goes via the second base station, and another split path of the split bearer goes via the first base station and not via the second base station. The controller configures either the SCG bearer or the split bearer without simultaneously configuring the bearers even if the user terminal indicates it supports both first and second architectures.
