Abstract: This application relates to the field of wireless communication technologies. The method includes: A terminal device receives a CGI reading command sent by a network device, and determines, based on a control parameter, a resource sharing manner of first measurement and CGI reading on an overlapped resource between a measurement resource of the first measurement and a reading resource of the CGI reading, where the control parameter is a parameter indicating that the first measurement and the CGI reading perform resource sharing on the overlapped resource. The terminal device performs the first measurement and the CGI reading in the determined resource sharing manner.
