    • A cellular radio communication system includes a first mobile terminal, a base station that performs radio communication with first mobile terminals, a second mobile terminal, and a second base station that performs radio communication with second mobile terminals. In the downlink communication, the base station selects a high data rate mode when the radio interference from the base station to the second mobile terminals that are located close to an edge of a communication area of the second base station is small. The base station selects an interference mitigation mode in the downlink communication when the radio interference from the base station to the second mobile terminals that are located close to the edge of the communication area of the second base station is large. Thus, inter-cell interference control can be performed in collaboration with base stations in the radio communication system without having communication interface between the base stations.
    • 蜂窝无线电通信系统包括第一移动终端,与第一移动终端进行无线通信的基站,第二移动终端以及与第二移动终端进行无线通信的第二基站。 在下行链路通信中,当从基站到位于第二基站的通信区域的边缘附近的第二移动终端的无线电干扰小时,基站选择高数据速率模式。 当基站到位于第二基站的通信区域的边缘附近的第二移动终端的无线电干扰较大时,基站选择下行链路通信中的干扰减轻模式。 因此,可以与无线通信系统中的基站协作地执行小区间干扰控制,而不需要基站之间的通信接口。

    • A transmitter station and receiver station have common maximum number of transmission bits per symbol of each subcarrier and information of encoding types to be selected. The transmitter station selects the modulation type from the propagation path quality of each subcarrier, executes encoding with the encoding type corresponding to the number of bits for communication with the selected modulation type, distributes the maximum number of transmission bits per symbol of each subcarrier by dividing the code, and transmits the data through modulation of only the number of bits for communication with the selected modulation type among distributed bits in each subcarrier. The receiver station executes demodulation by selecting the modulation type used for demodulation from the propagation path quality, summarizes the demodulation result with addition of reception of the signal having a zero degree of likeliness for the number of wanted bits, and executes decoding to the result of demodulation.

    • Transmission power relative to a propagation path having a variation in gain is controlled to increase communication channel capacity, and a data rate is controlled in accordance with the variation of the increased communication channel capacity. In order to increase the communication channel capacity, the transmission power is determined so that the sum of noise power (=received noise power/propagation path gain) converted into one at a transmitter and the transmission power becomes constant. As a result, contrary to the background art, the transmission power is controlled to be reduced when the propagation path gain decreases and to be increased when the propagation path gain increases.
    • 控制相对于具有增益变化的传播路径的传输功率以增加通信信道容量,并且根据增加的通信信道容量的变化来控制数据速率。 为了增加通信信道容量,确定发送功率,使得在发射机处转换为一个的发送功率和发送功率的噪声功率(=接收噪声功率/传播路径增益)之和变得恒定。 结果,与背景技术相反,当传播路径增益减小时,传输功率被控制为减小,并且当传播路径增益增加时传输功率被增加。
