Abstract: Embodiments of this application disclose a phase noise determining method and a related apparatus. The method includes: A first communication apparatus obtains a first signal, where the first signal includes a data signal and K phase-tracking reference signals PTRSs, where a value of an mth PTRS in the K PTRSs is determined based on a value of first interference, a value of second interference, and a preset receiving value of the mth PTRS, the first interference is inter-symbol interference generated by the data signal on the mth PTRS, the second interference is inter-symbol interference generated by a PTRS other than the mth PTRS in the K PTRSs on the mth PTRS, K and m are positive integers, and 1≤m≤K.

Abstract: This application provides example symbol processing methods and apparatuses. One example method includes generating a first symbol in a symbol sequence, where the first symbol and a second symbol have a same first symbol component, a start location of the first symbol component in the first symbol is a start location of the first symbol, a start location of the first symbol component in the second symbol is a location at which a cyclic prefix is truncated in the second symbol, the second symbol is a next symbol adjacent to the first symbol, and the first symbol and the second symbol each has a cyclic prefix. The first symbol can then be sent.
