Wireless communication method for time-frequency domain synchronization, terminal device, and network device

A terminal device, comprising a processor and a memory, wherein the memory has a computer program stored thereon, and the processor is configured to invoke and execute the computer program stored in the memory to perform:

• receiving first information transmitted by a network device, wherein the first information is associated with a first time period, and the first information is used to obtain at least one of:
• a first timing value, an offset rate of a first timing value, a rate of change of an offset rate of a first timing value, a first frequency offset value, an offset rate of a first frequency offset value, a rate of change of an offset rate of a first frequency offset value, first ephemeris information, the first time period, or one or more time domain positions corresponding to the first time period;
• wherein the first information is associated with the first time period comprises:
• the first information is associated with M time domain positions included in the first time period, where M is a positive integer greater than or equal to 1,
• wherein the first information is used to obtain at least one of:
• a first timing value corresponding to each of one or more of the M time domain positions, an offset rate of a first timing value corresponding to each of one or more of the M time domain positions, a rate of change of an offset rate of a first timing value corresponding to each of one or more of the M time domain positions, a first frequency offset value corresponding to each of one or more of the M time domain positions, an offset rate of a first frequency offset value corresponding to each of one or more of the M time domain positions, or a rate of change of an offset rate of a first frequency offset value corresponding to each of one or more of the M time domain positions,
• wherein the processor further performs:
• obtaining first timing values corresponding to the M time domain positions according to the first information.
