Abstract: This application provides a communication method and a communication apparatus. The method includes: receiving first information, where the first information indicates a manner of obtaining a timing advance (TA) of a first cell; and obtaining the TA of the first cell based on the first information. According to the technical solution provided in this application, the obtaining manner of obtaining the TA of the first cell is configured for the terminal apparatus based on the first information.

Abstract: The present disclosure relates to reference signal resource configuration methods and apparatuses. A reference signal resource configuration behavior of a base station is limited, and time division multiplexing is performed on different reference signal resources. Alternatively, a configuration behavior of a base station is not limited. When the base station configures concurrency of multiple reference signal resources, a terminal discards, according to a specific rule, a conflicting reference signal resource. Alternatively, a terminal may report its capability of processing a reference signal resource, and a base station appropriately configures a reference signal resource for the terminal based on the capability reported by the terminal.
