The interchange processing includes processing of supplying electric power to the user in the visit space.

Abstract: Disclosed is a radio base station (eNB1) provided with a storage unit (130) for storing base station information for selecting the destination of a message, a network communication unit (140) for transmitting the message to another radio base station selected according to the base station information, and a control unit (120) for controlling the storage unit (130) to set as base station information the priority level of the radio base station to which the message was sent according to the state of response to the transmitted message.

Abstract: A radio base station (eNB1) receives load information indicating the load level of different radio base station (eNB2) and adjusts a base station parameter, which is used for defining coverage, in accordance with a result of comparison between the load level of the radio base station (eNB1) and that of the different radio base station (eNB2). The radio base station (eNB1) corrects at least one of the load level of the radio base station (eNB1) and that of the different radio base station (eNB2), which are compared with each other, in accordance with a number of radio terminals connected to the radio base station (eNB1).

Abstract: A radio base station (eNB1), which is used in a radio communication system that can autonomously adjust, based on load information transmitted/received between radio base stations, the radio base station parameters used for defining coverage, comprises: a network communication unit (140) that can receive, from another radio base station, first load information indicating the load level of the other radio base station and that can transmit, to the other radio base station, a request for transmission of second load information the information amount of which is greater than that of the first load information; and a control unit (120) that, when the load level of the other radio base station indicated by the received first load information satisfies a given condition, controls such that the request for transmission of the second load information is transmitted to the other radio base station.

Abstract: A radio base station 100 judges a receiving state of a radio signal in conformity with the orthogonal frequency division multiplexing scheme, and changes a symbol string configuration of a symbol string defined by a size in a frequency axis direction and in a time axis direction, on the basis of the judged receiving state.

Abstract: Upon receipt of an RLF Indication message indicating a failure in a handover where a radio base station eNB10-1 is the handover source from the other radio base station eNB, the radio base station eNB10-1 can recognize that its coverage is not adjusted appropriately by referring to the RLF Indication message. Moreover, the radio base station eNB10-1 can adjust coverage appropriately by expanding the radiation area of the antenna 101 whose radiation area is directed toward the other radio base station eNB being the handover target, among the antennas 101 included in the radio base station eNB10-1.

Abstract: A radio base station (100) is provided with a stream determination unit (141) for determining whether communication quality of a radio communication channel between the radio base station (100) and a receiving device is lower than a predetermined threshold, and an antenna selector (142) for selecting, from among transmitting antennas (131-134), transmitting antennas such that the distance between the transmitting antennas (131-134) becomes shorter than that before the communication quality is determined to be lower than the predetermined threshold when the communication quality is determined to be lower than the predetermined threshold.

Abstract: A wireless communication apparatus, having a plurality of antennas 11-1 to 11-M and for diversity-combining signals received by the plurality of antennas 11-1 to 11-M, is provided with a combining information calculation unit 14 for calculating antenna combined amplitude and combining weights based on received power of the plurality of antennas 11-1 to 11-M, a combining unit 15 for weighting and combining the signals received by the plurality of antennas 11-1 to 11-M based on the combining weights calculated, and a decoding processing unit 16 for decoding a combined reception signal generated by the combining unit 15. It thereby improves fading durability of the decoding process by reducing influence of multipath fading caused by arrival waves with delays, even in a case of using only a small number of reception antennas, and maintains a stable reception condition consistently, as well as achieving downsizing of and reduction in cost of hardware.
