    • For example, in a radio communication system using an OFDMA method, frequency bandwidth allocated to each sector is modified according to, for example, the number of terminals existing in each sector, and the effective utilization of radio sources is promoted. A radio base station device includes unit to determine the amount allocated to each sector from the amount of radio resources in the base station and unit to switch over the connection states of a plurality of radio resources obtained by dividing the entire radio resources that can be allocated to each sector in the base station according to the determined amount of allocation.
    • 例如,在使用OFDMA方式的无线通信系统中,分配给各扇区的频带根据例如每个扇区中存在的终端的数量进行修改,促进无线源的有效利用。 无线基站装置包括从基站中的无线资源量决定分配给每个扇区的量的单元,以及切换通过划分可分配的整个无线资源得到的多个无线资源的连接状态的单元 根据确定的分配量,在基站中的每个扇区。

    • Provided is a non-aqueous secondary battery that uses a lithium-containing metal oxide that contains manganese as a positive electrode active material, and wherein a small internal resistance and a high electric capacity can be maintained even after high-temperature storage or charge and discharge at high temperatures, by suppressing elution of manganese from the positive electrode active material. Specifically provided is a non-aqueous electrolyte secondary battery with a negative electrode capable of intercalating and deintercalating lithium ions, a positive electrode with a lithium-containing compound as the positive electrode active material, and a non-aqueous electrolyte that has lithium salt dissolved in an organic solvent. Said non-aqueous electrolyte secondary battery is characterized by the lithium-containing compound being a lithium-containing metal oxide compound that contains manganese and by the non-aqueous electrolyte containing a fluorosilane compound indicated by general formula (1). (In the formula, R1 to R3 independently represent an alkyl group having 1 to 8 carbon atoms, an alkenyl group having 2 to 8 carbon atoms, a cycloalkyl group having 5 to 8 carbon atoms, an aryl group having 6 to 8 carbon atoms, or a fluorine atom, and R4 represents an alkylene group having 1 to 8 carbon atoms or an alkylene group having 4 to 8 carbon atoms and having an ether group.)
