Embodiment Construction
[0024] The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0025] The technical solutions proposed in this application can be applied to various communication systems, such as Global System for Mobile Communications, LTE Frequency Division Duplexing System, LTE Time Division Duplexing System, Universal Mobile Communications System, New Wireless System, and subsequent evolved communication systems.
[0026] Direct communication (Sidelink Communication, SC) technology refers to the communication technology between devices. It is a new technology that allows terminal devices to communicate directly by multiplexing cell resources under the control of the system.
[0027] Based on direct communication technology, Vehicle-to-Everything (V2X) services can be carried out. V2X means that the car can be interconnected with the surrounding environment. The surrounding environment includes cars,...

The embodiment of the invention discloses a frequency processing method and device, terminal equipment and a storage medium. In the frequency processing method, a first frequency is a frequency at which direct communication is currently carried out between first terminal equipment and second terminal equipment, and the first terminal equipment can use the first frequency to send indication information to the second terminal equipment so as to indicate a direct communication frequency to be switched, such as a second frequency, of the first terminal equipment. Thus, the second terminal equipment can obtain the direct communication frequency to be switched of the first terminal equipment before the first terminal equipment is switched from the first frequency to the second frequency, thereby facilitating the second terminal equipment to switch the current direct communication frequency from the first frequency to the second frequency. The continuity of direct communication service between the two pieces of terminal equipment is kept.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a frequency processing method, device, terminal equipment and storage medium. Background technique [0002] With the continuous increase of wireless services, the base station-centered service provision method can no longer meet the service needs of a large number of users in different environments. Therefore, sidelink communication (Sidelink Communication) is introduced into the new generation of 5G (New Radio, NR) communication , SC) technology. In the direct communication technology, terminal devices can communicate directly with each other, and terminal devices can directly obtain resources for direct communication from a base station, or select resources for direct communication from a pre-configured resource pool. Although resources that can be used for direct communication can include multiple frequencies, in the current protocol version, terminal devi...
