Abstract: A cell selection or reselection method includes that a terminal device obtains first information that corresponds to a first cell and that is not specific to a frequency band or a frequency. When a first condition that corresponds to the first information and that is used to determine whether the terminal device can access the first cell is not met, the terminal device is allowed to select or reselect a cell on a same frequency as the first cell.

Abstract: A message relay arrangement is described. A first terminal sends a first message to a second terminal, where the first message that instructs the second terminal to determine a type of the second terminal based on the first message. Based on the terminal type, the second terminal operating as the first-type terminal sends first measurement information; or operating as the second-type terminal receives first measurement information sent by a first-type terminal, determines quality of a first link between the first-type terminal and the second-type terminal, and sends the quality of the first link to the first terminal. The first terminal receives the quality of the first link sent by the second-type terminal. The first terminal determines a mapping relationship between the first-type terminal and the second-type terminal based on the quality of the first link. The first terminal sends the mapping relationship to terminals corresponding to the mapping relationship.
