    摘要： In the preferred embodiment, the transmission length of the non-full rate frame is shortened frame in order for the mobile terminal 100 to monitor other frequencies with a single receiver. Modulated symbols of non-full rate frame are transmitted with reduced repetition maintaining the sum of repeated symbol energy. Generally, for 1/n (n=2,4,8) length transmission, 1/m (m≧n) rate frame repeated m/n times and transmitted with n/m symbol energy of the full rate frame. The system may use rate limitation to generate a non-full rate frame. A position of the transmitted symbols may be randomized by a mobile specific predetermined random code to minimize interference between terminals different from each other. For intensive frequency scanning and synchronization signal transmission, non-transmitting period can be assigned for successive frames of some interval. For 1/n (n=2,4,8) length successive transmission, the starting position of the transmitted symbols are staggered by 1/n frame time in each frame. If there is no part of the frame to be staggered, the starting position is the beginning of the frame. Such implementation minimizes guard time overhead for frequency switching and resynchronization.

    摘要翻译： 在优选实施例中，非全速率帧的传输长度是缩短的帧，以便移动终端用单个接收机监视其他频率。 非全速率帧的调制符号以减少的重复传输，保持重复符号能量之和。 通常，对于1 / n（n = 2,4,8）长度传输，1 / m（m> = n）速率帧重复m / n次，并以全速帧的n / m符号能量发送。 系统可以使用速率限制来生成非全速率帧。 发送符号的位置可以通过移动专用预定随机码进行随机化，以最小化彼此不同的终端之间的干扰。 对于强化频率扫描和同步信号传输，可以为一些间隔的连续帧分配非发送周期。 对于1 / n（n = 2,4,8）长度连续传输，发送符号的起始位置在每帧中以1 / n帧时间交错。 如果没有帧的部分交错，起始位置是帧的开头。 这样的实现使得用于频率切换和重新同步的保护时间开销最小化。 重复时间可以是整数重复或部分重复次数。
