摘要： Provided is a frame structure for filtered OFDM signaling, wherein once every frame a central controller passes redundant broadcast data for a short time (e.g. 16 symbol times) over all frequencies in use. This broadcast, called a beacon, may carry control information, frame structure information, and other data. The rest of the frame is divided into other assignments, including broadband redundantly coded channels for broadcast, ALOHA contention access, or point-to-point transmissions, and including traffic channels that may use only some of the assigned frequencies intended primarily for point-to-point access. This allows a mix of TDMA and FDMA point-to-point and broadband access. This system may be controlled by a central coordinator, which issues reservations. This system allows devices on a frequency-selective channel to communicate with scheduled operations.
摘要翻译：提供了一种用于经滤波的OFDM信令的帧结构，其中中央控制器每帧一次在所使用的所有频率上短时间（例如16个符号时间）通过冗余广播数据。称为信标的这种广播可以携带控制信息，帧结构信息和其他数据。帧的其余部分被划分成其他分配，包括用于广播的宽带冗余编码信道，ALOHA争用接入或点到点传输，并且包括可以仅使用一些分配频率的业务信道，主要用于指向点访问。这允许TDMA和FDMA点对点和宽带接入的混合。这个系统可能由一个发出保留的中央协调员控制。该系统允许频率选择信道上的设备与预定的操作进行通信。
