  • Publication number: 20230396353
    Abstract: A communication method includes, when a rate adaptation or a frequency offset adjustment is performed on a first block sequence, a quantity of first preset blocks that are added or deleted is one of one or more preset values. In this way, a receive end may determine, based on whether the quantity of first preset blocks in the received first block sequence is a preset value, whether an exception occurs in the first preset block during transmission. Based on this, a false packet can be accepted as a correct packet less frequently, thereby improving a mean time to false packet acceptance (MTTFPA) indicator.
