The present disclosure relates to communication methods and devices. One example method includes sending, by a first network device, a first parameter to a second network device, where the first parameter is used to indicate a proportion of measurement gap sharing between different measurement types. The first network device has a radio link control layer function, a media access control layer function, and a physical layer function. The second network device has a packet data convergence protocol layer function, a service data adaptation protocol layer function, and a radio resource control layer function.
