A wireless communication method, including: obtaining, by a network device, at least one of information that is about sharing a local oscillator by a plurality of transceiver units and that is sent by a terminal device, information that is about phase noise errors measured on a plurality of phase tracking reference signal ports and that is sent by the terminal device, isolation between a plurality of channels used to carry phase tracking reference signals, and status information of the channels used to carry the phase tracking reference signals; determining port configuration information of a phase tracking reference signal based on the at least one of the information about sharing a local oscillator, the information about the phase noise errors, the isolation between the plurality of channels used to carry the phase tracking reference signals, and the status information of the channels used to carry the phase tracking reference signals.
