    • A transmission method for use in a multi-hop wireless communication system is provided. The system includes a source apparatus, a destination apparatus and one or more intermediate apparatuses. The system has access to at least one predetermined transmission introduction sequence and also has access to a time-frequency format for use in assigning available transmission frequency bandwidth during a discrete transmission interval, said format defining a plurality of transmission windows within such an interval. Each window occupies a different part of that interval and has a frequency bandwidth profile within said available transmission frequency bandwidth over its part of that interval. Each said window being assignable for such a transmission interval to at least one of said apparatuses for use in transmission. The method includes, when transmitting a message with a preamble in a particular transmission interval, transmitting the preamble in a first transmission window of that transmission interval. Furthermore, the method includes transmitting the transmission introduction sequence in a second transmission window of that transmission interval other than the first transmission window preferably as control information for use by at least one said intermediate apparatus or the destination apparatus.
    • 提供了一种用于多跳无线通信系统的传输方法。 该系统包括源设备,目的地设备和一个或多个中间设备。 该系统可以访问至少一个预定的传输介绍序列,并且还可以访问用于在离散传输间隔期间分配可用传输频率带宽的时间 - 频率格式,所述格式在这样的间隔内定义多个传输窗口。 每个窗口占据该间隔的不同部分,并且在该间隔的部分内在所述可用传输频率带宽内具有频带配置。 每个所述窗口可分配给用于传输的所述设备中的至少一个的这种传输间隔。 该方法包括:在特定发送间隔中发送具有前导码的消息时,在该发送间隔的第一发送窗口中发送前导码。 此外,该方法包括:在第一传输窗口之外的传输间隔的第二传输窗口中优选地传输传输介绍序列作为至少一个所述中间设备或目的设备使用的控制信息。
