A communication method, a related apparatus, and a storage medium are provided, to resolve transparent transmission of clock frequency information of a service. In this application, a first communication apparatus receives a first service data stream, generates a first code block stream based on the first service data stream, and sends the first code block stream. The first code block stream includes first clock frequency information, and the first clock frequency information indicates transmission duration of k first data frames of the first service data stream, and/or a moment at which the k first data frames of the first service data stream are received. In this way, a second communication apparatus may send the k first data frames based on the first clock frequency information, so that a clock frequency of the k first data frames sent by the second communication apparatus are basically consistent with a clock frequency of the k first data frames received by the first communication apparatus. This can resolve transparent transmission of clock frequency information of a service.
