Abstract: A block generation method and apparatus, and a block receiving method and apparatus are disclosed. The block generation method includes: generating a first block and a second block, where the first block includes a first block unit, the second block includes a second block unit, a first indicator is configured in the first block unit, and the first indicator is used to indicate whether the second block unit is a control code; and sending the first block and the second block. According to this method, an indicator is configured in a block unit in the first block to indicate whether an adjacent block is a control code, so that a boundary between a control code and a data code is determined, thereby avoiding extra indication information for an indication and reducing overheads of the indication information.

Abstract: An embodiment of this application provides a data transmission method. The method includes: A first communication apparatus sends an ith AM group to a second communication apparatus, and sends first data of a plurality of service flows to the second communication apparatus based on a mapping relationship. The first data is carried in M time units between the ith AM group and an (i+1)th AM group, the mapping relationship is a mapping relationship between a slot of a first calendar and the plurality of service flows, and the first calendar includes s slots. The M time units between the ith AM group and the (i+1)th AM group include N first counting periods, each time unit of the first counting period corresponds to one slot of the first calendar, and different time units of a same first counting period correspond to different slots of the first calendar.

Abstract: Embodiments of this application provide a method. A receiving device determines that a first PHY needs to be added to a first FlexE group in a working state; performs deskew on the first PHY or each PHY in the first FlexE group based on a received data stream corresponding to the first PHY and a received data stream corresponding to each PHY in the first FlexE group, and restores a data stream corresponding to a client from a PHY in the first FlexE group; and if skew between the data stream corresponding to the first PHY and the data stream corresponding to each PHY in the first FlexE group after the deskew is performed is zero, restores a data stream corresponding to a client from a PHY in a second FlexE group. Flexibility of adjusting a PHY in a FlexE group in a working state is improved.
