摘要： A first radio base station (1A) measures the power of an interference, which is caused by a radio signal transmitted over a second uplink from a radio terminal (2B) to a second radio base station (1B), for one resource block or each of a plurality of resource blocks allocated to a radio terminal (2A), and further calculates a traffic amount ratio in the first radio base station (1A). Moreover, the first radio base station (1A) multiplies the interference power value for each resource block by the traffic amount ratio measured by a communication load measuring unit (152), then generates interference information for each resource block, which corresponds to the multiplication result value for each resource block, and then transmits the interference information to the second radio base station (1B).

摘要： A radio communication system (10A) has a transmission system (20A) and a radio terminal (300). The transmission system (20A) superimposes and transmits a delay stream (S1delay) and a communication stream (S1), and superimposes and transmits a delay stream (S2delay) having a different delay than the delay stream (S1delay) and a communication stream (S2). A transmission system (20A) notifies delay information (S1info) about the delay stream (S1delay) and delay information (S2info) about the delay stream (S2delay). The radio terminal (300) combines the communication stream (S1) and the delay stream (S1delay) in accordance with the notified delay information (S1info), and combines the communication stream (S2) and the delay stream (S2delay) in accordance with the notified delay information (S2info).

摘要： Based on a first weighting factor adopted for a first wireless base station 1-1 to direct its beam to a wireless communication apparatus 3, a communication control apparatus 2 calculates a second weighting factor so that the wireless communication apparatus 3 does not interfere with a second wireless base station 1-2 neighboring the first wireless base station 1-1 and the second wireless base station 1-2 interpolates a dead region of the first wireless base station 1-1, and transmits the second weighting factor to the second wireless base station 1-2 to generate a beam.

摘要： A communication control method for a communication system including a plurality of wireless base stations 1 having adaptive array antennas and a communication control apparatus 2, stores location information indicating an interference region by wireless base stations 1-1 and 1-2 neighboring each other, a first weighting factor for the wireless base station 1-1 to direct its beam to the interference region, and a second weighting factor for the wireless base station 1-2 to direct its beam, correspondingly to one another in an interference table 23, judges whether a terminal 3 is located in the interference region by obtaining weighting factors adopted by each of the wireless base stations 1-1 and 1-2 while the wireless base station 1-1 communicates with the terminal 3, and comparing the weighting factors to the first and the second weighting factors stored in the interference table 23, and controls beam generation of the wireless base station 1-2 to prevent its interference when the terminal 3 is located in the interference region. Thereby, the communication is stabilized without the interference by the neighboring wireless base station.

摘要： Upon receipt of a new channel allocation request from a mobile communication terminal, a suitable channel is allocated. A base station device performs communication with communication terminals by implementing an adaptive process using a plurality of antennas, and includes an interference recognizing unit that recognizes a level of interference on empty channels for use in the communication, a channel selector that selects an empty channel to be allocated based on a result recognized by the interference recognizing unit, and a channel allocator that, when there is a new channel allocation request from a communication terminal, allocates the empty channel selected by the channel selector to that communication terminal.

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.
