Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0032] This patent designs a resource allocation scheme for LTE-based Internet of Vehicles, which uses the periodic characteristics of Internet of Vehicles services and adopts a semi-static resource allocation method, that is, once a communication resource is selected, it will be occupied within a certain occupation time. Communication resources, and ...

Abstract

This application discloses a resource allocation method for the Internet of Vehicles, which solves the resource collision problem of the Internet of Vehicles. Physical resource blocks: detecting energy values ​​of subbands on multiple subframes, and selecting subbands and subframes corresponding to consecutive physical resource blocks whose energy values ​​are less than a threshold as communication resources. Take 100 subframes as a period, and the occupation time of communication resources is an integer multiple of the period. After the occupation time is exhausted, the energy of subbands on multiple subframes is re-detected, and the subbands and subbands corresponding to the continuous physical resource blocks with energy less than the threshold are selected. Frame, as a new communication resource. The solution of the present application can improve the resource utilization efficiency of the Internet of Vehicles.

Description

technical field [0001] The present application relates to the field of mobile communication, and in particular to a method for allocating resources used by communication links in a communication system of the Internet of Vehicles. Background technique [0002] The widespread deployment of LTE gives vehicle companies the opportunity to use the LTE network for interconnection between vehicles. However, in the scenario without base station coverage, the vehicle is outside the coverage of the base station and cannot use the base station for scheduling control. At this time, the vehicle can only use competitive way to obtain transmission resources. In the existing LTE device-to-device (D2D) communication technical solution, the vehicle terminal equipment (V-UE) pre-configures a resource pool for contention transmission. When the V-UE finds that it is outside the coverage of the base station, it selects a pre-configured resource pool, and when data arrives, it randomly selects a ...
