Embodiment Construction

[0231] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0232] This embodiment is applied in communication systems such as D2D. In a possible implementation manner, the communication system may be based on V2X (Vehicle to Everything, vehicle networking technology), which is a new generation of information communication technology that connects vehicles with everything. Among them, V represents a vehicle, and X represents any object that in...

Abstract

The present disclosure relates to a resource switching method, and a resource allocation method, apparatus, device and system, and belongs to the technical field of communication. The resource switching method includes the steps: when a terminal determines that a first BWP currently used needs to be switched, the terminal selects a second BWP among the at least two BWPs configured in advance; andthe terminal switches from the first BWP to the second BWP. The resource switching method can configure and switch the BWP by the terminal without requiring the access network device to specify the BWP for the terminal, and can introduce the BWP in the communication system supporting large bandwidth such as D2D, thus saving the power consumption of the terminal in the communication system, and being possible to ensure the communication effect of the terminal by switching the BWP in time.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a resource switching method, a resource allocation method, a device, a device, and a system. Background technique [0002] The smallest bandwidth in 5G (5Generation, fifth-generation mobile communication technology) is 5MHz, and the largest bandwidth is 400MHz. If all terminals are required to support a bandwidth of 400MHz, since the size of the bandwidth is positively correlated with the sampling rate, if the sampling rate corresponding to the 400MHz bandwidth is used for sampling, the power consumption of the terminal will be high. [0003] Since the terminal cannot occupy the full 400MHz bandwidth at the same time, in order to save the power consumption of the terminal, the access network device may allocate a BWP (Bandwidth Part, bandwidth part) to the terminal. That is, the bandwidth allocated by the access network device to the terminal can change dy...
