    • When there is a connection request to a base station supporting adaptive modulation from a terminal supporting adaptive modulation, the base station measures a D wave level that indicates communication environment of the transmission path. When the measured D wave level is not lower than a threshold value of D wave level at which communication is possible by a modulation method (16QAM) having larger multi-value number, the base station permits allocation of a wireless channel to the terminal. Therefore, even when the modulation method is switched from one having smaller multi-value number (π/4 shift QPSK) to one having larger multi-value number (16QAM) during communication after channel allocation to the terminal, degradation of communication quality due to the communication environment of the transmission path can be prevented.
    • 当从支持自适应调制的终端支持自适应调制的基站有连接请求时,基站测量表示传输路径的通信环境的D波电平。 当测量的D波电平不低于具有较大多值数的调制方法(16QAM)可能进行通信的D波电平的阈值时,基站允许向终端分配无线信道。 因此,即使在通信分配到终端之后的通信期间,从具有较小多值数(pi / 4移位QPSK)的调制方法切换到具有较大多值数(16QAM)的调制方法时,由于 可以防止传输路径的通信环境。

    • A flame retardant includes magnesium-hydroxide particles that contain at least one transitional metal compound. The at least one transitional metal compound is at least one compound selected from a group consisting of copper compound, cobalt compound, nickel compound, zinc compound and titanium compound. The at least one transitional metal compound is contained in the magnesium-hydroxide particles with the content of 100 to 1000 mass ppm in terms of metals. In addition, the total content of the copper compound, the cobalt compound and the nickel compound is 1000 mass ppm in terms of metals or less while the total content of the zinc compound and the titanium compound is 1000 mass ppm or less.
