Abstract
Implementations of the present disclosure relate to a wireless communication method and a terminal device. The method includes: detecting, by a terminal device, a first type of Synchronous Signal Block (SSB) at a frequency on an asynchronous raster; determining, by the terminal device, a frequency domain position of a Control Resource Set (CORESET) of Remaining Minimum System Information (RMSI) associated with the first type of SSB based on the first type of SSB.

- determining, by the terminal device, a second offset;
- and
- determining, by the terminal device, the frequency domain position of the CORESET of the RMSI according to a first offset, the second offset, and a frequency domain position of the first type of SSB;
- wherein, a size of the first offset is a size of an offset between a reference frequency domain position of a second type of SSB and the frequency domain position of the CORESET of the RMSI, the second offset is an offset between the frequency domain position of the first type of SSB and a reference frequency domain position of the second type of SSB, or, the second offset is an offset between a first frequency and a second frequency, and the second type of SSB is an SSB transmitted on a synchronous raster, the first frequency is a frequency where the terminal device detects the first type of SSB on an asynchronous raster, and the second frequency is a frequency on a synchronous raster in a sub-band where the first frequency is located;
- wherein the first offset is:
- an offset between a minimum RB of the second type of SSB and a minimum RB of the CORESET of the RMSI.
