Abstract: A method of generating a packet of a physical layer transmitter of a TV white space (TVWS) wireless personal area network (WPAN) system operating a WPAN service in TVWS is provided. A packet that is generated by the method of generating the packet includes a preamble, a start frame delimiter that is positioned after the preamble, a first physical layer header that is positioned after the start frame delimiter, and a physical layer service data unit that is positioned after the first physical layer header. Here, the first physical layer header represents whether the packet is a ranging packet for ranging, and includes a ranging packet identification bit corresponding to a reserved bit of the second physical layer header in a SUN system and a LECIM system, and a parity bit.

Abstract translation: 提供了一种在TVWS中生成运行WPAN服务的TV空白（TVWS）无线个域网（WPAN）系统的物理层发送机的分组的方法。 通过生成分组的方法生成的分组包括前导码，位于前导码之后的起始帧分隔符，位于起始帧定界符之后的第一物理层报头，以及物理层服务数据单元， 位于第一个物理层标题之后。 这里，第一物理层标题表示分组是否是用于测距的测距分组，并且包括与SUN系统和LECIM系统中的第二物理层报头的保留位相对应的测距分组标识位和奇偶校验位。
