    • A base station apparatus is used in a region in which a first system and a second system co-exist. In the first system, mobile communication is conducted using a variable system bandwidth not more than a basic bandwidth. In the second system, mobile communication is conducted using a variable system bandwidth which is not more than a bandwidth of an advanced system band which is at least as wide as multiple of the basic bandwidths. The base station apparatus generates a control signal for the first system and a control signal for the second system, orthogonally multiplexes them, and includes the same in a downlink signal to transmit the downlink signal. The advanced system band is divided such that it includes multiple of areas (P, Q, R, S) of the basic bandwidth. The control signal for the first system is included in one of the areas (Q). The control signal for the second system is included in at least one of the areas (P, Q, R, S).
    • 在第一系统和第二系统共存的区域中使用基站装置。 在第一系统中,使用不超过基本带宽的可变系统带宽进行移动通信。 在第二系统中,使用不大于基本带宽的倍数的高级系统频带的带宽的可变系统带宽进行移动通信。 基站装置生成用于第一系统的控制信号和第二系统的控制信号,对它们进行正交复用,并将其包含在下行链路信号中以发送下行链路信号。 先进的系统频带被划分为包括基本带宽的多个区域(P,Q,R,S)。 第一系统的控制信号被包括在区域(Q)之一中。 第二系统的控制信号包括在区域(P,Q,R,S)中的至少一个中。
