Abstract: This application discloses a code block identification method and related apparatus. The method includes: obtaining a code block stream, where the code block stream includes a first code block; determining a to-be-identified bit pattern and comparing the to-be-identified bit pattern with a template bit pattern to obtain a quantity of inconsistent bits; and identifying the first code block as a first boundary code block when the quantity of inconsistent bits is less than or equal to a first threshold. The to-be-identified bit pattern includes a first bit pattern and corresponds to the first code block. The template bit pattern includes a first template bit pattern and corresponds to the first boundary code block.

Abstract: The technology of this application relates to a rate adaptation method and apparatus. The method includes, when a rate adaptation requirement exists, inserting a rate adaptation code block only between two adjacent code blocks whose code block relationship meets a preset condition, or deleting only a rate adaptation code block between two code blocks whose code block relationship meets a preset condition. In this way, it can be ensured that correctness of parsing a packet by a receive side after the receive side receives the packet is not affected by rate adaptation, and reliability of rate adaptation can be improved.

Abstract: A communication method, device, and a storage medium to resolve a problem that information about a clock frequency and a clock phase of a service cannot be correctly transmitted to a receiver or correctly recovered because transparent transmission of the information about the clock frequency and the clock phase of the service cannot be implemented. Because a value of k based on a reference data unit is inserted into a second data flow, and the value of k can indicate a quantity of third data units included between a second data unit and the reference data unit in a first data flow, a receive end device can completely recover the first data flow based on the value of k.

Abstract: Embodiments of this application provide a communication method, a communications device, and a storage medium, to process an invalid block in a data stream. In embodiments of this application, N first block streams are obtained, where N is a positive integer. When there is an invalid block in the N first block streams, the invalid block in the N first block streams is converted into a target block, to obtain a to-be-sent block stream. Then, the to-be-sent block stream is sent. Because the invalid block in the block stream is checked and converted into the target block, an error that occurs in service data at a receive end and that is caused by the invalid block can be reduced.
