Abstract: A master evolved Node-B (MeNB) connects to a user terminal together with a secondary evolved Node-B (SeNB) in a dual connectivity scheme. The MeNB includes: transmitter configured to transmit a message to the SeNB via an X2 interface. The message is an SeNB addition request message or an SeNB modification request message. The message includes identification information of a serving gateway connected with the MeNB via an S1 interface. The identification information includes an S1 tunnel endpoint ID (S1-TEID) of the serving gateway or an internet protocol (IP) address of the serving gateway.

Abstract: A communication control method is a method for performing an offload from a cellular RAN to a wireless LAN. The communication control method includes the steps of: transmitting a list which contains identifiers of wireless LAN access points included in the wireless LAN, by a cellular base station included in the cellular RAN; receiving the list, by a user terminal which has a cellular communication unit and a wireless LAN communication unit; and performing an operation related to the offload after detecting that the user terminal approaches a wireless LAN access point on the basis of the list, by the user terminal which exists in a cell of the cellular base station.

Abstract: A mobile communication system performs downlink multi-antenna transmission by applying a precoder matrix that defines transmission directionality of downlink and a rank that defines number of signal sequences of the downlink. The mobile communication system comprises a user terminal that feeds back feedback information of a target frequency band, to a base station. The feedback information includes combinations of precoder matrix information indicating the precoder matrix and rank information indicating the rank.
