摘要： 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).

摘要： 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.

摘要： A macro-cell base station (MeNB) transmits, via a PDCCH in a first subframe, both allocation information indicating a radio resource allocated to a radio terminal (MUE) and subframe information indicating a second subframe which is later than the first subframe and in which an allocation is applied in accordance with the allocation information. The radio terminal (MUE) receives the allocation information and the subframe information from the macro-cell base station (MeNB) via the PDCCH in the first subframe. The macro-cell base station (MeNB) omits the transmission of the allocation information in the second subframe, while the reception unit on the terminal side omits the reception of the allocation information in the second subframe.

摘要： A first radio base station (1A) calculates a traffic amount ratio in the first radio base station (1A). Further, when the traffic amount ratio is equal to or greater than a threshold value, the first radio base station (1A) controls to transmit interference information. Under this control, the first radio base station (1A) performs a measurement of interference power, a generation of the interference information and the transmission of the interference information to a second radio base station (1B). On the other hand, when the traffic amount ratio is less than the threshold value, the first radio base station (1A) controls to halt the transmission of the interference information. Under this control, the first radio base station (1A) performs none of the measurement of interference power, the generation of the interference information and the transmission of the interference information to the second radio base station (1B).
