A communication method, a communications apparatus, and a storage medium, used for a terminal device. The method includes: receiving system information from a first cell, where the system information includes first information; and performing cell selection or cell reselection based on the first information. In the embodiments, assistance information, such as a receiving capability of a network device or a sending capability of the terminal device, may be added to the system information. The assistance information includes the first information, so that when performing the cell selection or the cell reselection, the terminal device considers more determining conditions, to prevent some terminal devices with a low sending capability from camping on an NTN that cannot work.
