Abstract: A base station according to a first aspect is configured to transmit a radio signal to a user terminal in an own cell by using a plurality of transmission antennas. The base station comprises: a controller configured to notify the user terminal of a multi-antenna transmission mode to be applied to a transmission of the radio signal; and a transmitter configured to transmit the radio signal by using the plurality of transmission antennas by the multi-antenna transmission mode notified to the user terminal. The controller reduces a number of transmission antennas to be used for the transmission of the radio signal so as to reduce power consumption of the base station. The controller maintains the multi-antenna transmission mode notified to the user terminal without changing the multi-antenna transmission mode, even when reducing the number of transmission antennas to be used for the transmission of the radio signal.

Abstract: A communication control method according to one embodiment is used in a mobile communication system. The communication control method comprises a step A of predicting, by a UE, a radio condition within a second period after connection between the UE and a eNB is established, in a first period for which the connection is not established, and a step B of performing, by the UE, a random access procedure for establishing the connection. The step B includes a step of performing notification of information on the predicted radio condition from the UE to the eNB in the random access procedure. The information is used, by the eNB, for controlling communication with the UE.

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.
