Abstract: Embodiments of the present invention disclose a signal transmission method, including: sending, by a first device, a first reference signal to a second device, where the first reference signal is used for phase tracking; the first reference signal is mapped to a first symbol; the first symbol includes a symbol that carries a data signal and that precedes a second symbol; the second symbol is one or more consecutive symbols carrying a DMRS; and the one or more symbols include the 1st symbol carrying the DMRS. According to the foregoing solution, it can be ensured that a PT-RS is also mapped to a symbol to which a data channel is mapped and that precedes a symbol carrying a DMRS, thereby ensuring phase noise estimation performance.

Abstract: A communication method and apparatus resolve invalid communication in a packet loss scenario of an XR service, so that device power consumption is reduced, and communication resources are saved. A first communication device obtains information about a data unit to which a data packet belongs, where the data unit includes one or more data packets. The first communication device discards a data packet that is being transmitted and a data packet that is not transmitted that are in the data unit. The first communication device sends indication information to a second communication device, where the indication information includes the information about the data unit.
