当数据接收装置获取到待传输数据帧对应的帧头信息和第一开销信息之后，数据接收装置就要根据预设传输指示确定出待传输数据帧对应的第一传输模式了。

本发明实施例中，感知模式和终结模式同时存在时，终结模式传输的 port和感知模式传输的port不能出现相同值。
示例性的，将PHY0，PHY2，PHY4进行绑定，有效时隙数分别为2，1，9，那么PHY0在开销位置扩展的20个66B块中有2个有效数据，这两个有效数据为PHY0和PHY2的开销；PHY1在开销位置扩展的20个66B块中，有效数据有1个，这1个为PHY4的开销；PHY4在开销位置扩展的20个66B块中，有效数据为9个，则将这9个全部填充pad，这样就完成了开销数据的移动。
示例性的，如图4所示，进行交织后的开销数据的格式为：PHY0上的位置0和位置1处填充OH0和OH2这两个开销，PHY2上的位置0处填充OH4这个开销，PHY4上填充9个pad。
在一些实施例中，在根据第一传输模式，对帧头信息和第一开销信息进行对应的处理之前，flexe_rx_deskew模块对相同GROUP的PHY之间进行去偏移，并根据PHY Number将PHY按照从小到大的顺序进行重新排列。
S104、将待传输数据发送至待接收接口。
