Abstract: A communications method includes a terminal device receives broadcast information sent by a network device, where the broadcast information includes first information indicating N configuration parameters and a plurality of pieces of second information indicating Mi configuration parameters. Then, the terminal device determines configuration information of an ith reference signal based on some or all of the configuration parameters indicated by the first information and the Mi configuration parameters indicated by the ith piece of second information, where the configuration information of the ith reference signal includes Qi configuration parameters, and Qi is greater than or equal to N, and Qi is greater than or equal to Mi. The method reduces signaling overheads of the broadcast information.

Abstract: Embodiments of this application provide a communication method, device, and system, to reduce energy consumption of a terminal device and accelerate reselection performed by the terminal device. In this solution, a network device determines a plurality of sub-areas, and sends area configuration information to the terminal device. The terminal device receives the area configuration information, determines a first sub-area based on the area configuration information, and performs measurement based on information about one or more neighboring frequencies corresponding to the first sub-area. A geographical area range including the plurality of sub-areas includes a coverage area of a first cell, the area configuration information indicates information about the plurality of sub-areas, and the first sub-area is a sub-area in which the terminal device is currently located in the plurality of sub-areas.
