Problems solved by technology

[0082] This working method is mainly considered for roadside equipment, which can avoid the mutual interference of different working methods. This processing method will cause the vehicle terminal to reduce the transmission performance due to the reduction of the working frequency range and the increase of the channel utilization rate.

Embodiment Construction

[0123] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0124] Figure 5 It is a flow chart of the method for different terminal types to communicate with the Internet of Vehicles in the present invention; as Figure 5 said,

[0125] Both the terminal and the base station are preset with parameters of the overall frequency space M and its sub-frequency space N;

[0126] Step 501, for terminals with preset parameters (including vehicle-mounted equipment and roadside equipment), or when there is no network coverage, work in frequency space N according to preset parameters;

[0127] Step 502, for the terminals configured by the base station (including vehicle-mounted equipment and roadside equipment), obtain configuration information from the base station;

[0128] The way to obtain the information her...

Abstract

The invention discloses a method and a system for sharing a frequency spectrum by multiple working mode terminals of Internet-of-vehicles, relates to the field of Internet-of-vehicles communication, and particularly relates to a method and a system for sharing a frequency spectrum by a direct connection communication terminal (roadside equipment and a vehicle-mounted terminal) realized by utilizing LTEV2X (PC5, Sidelink) specifications. At present, a unified working frequency band is allocated to direct connection communication of roadside equipment and a vehicle-mounted terminal in China, related equipment types are numerous, different working modes exist, and if the related equipment types are not restrained, serious interference can be possibly generated, and the target of system designcannot be achieved. According to the method, an efficient and flexible spectrum division scheme is provided on the basis of whether to accept base station configuration and different scheduling modesof transmitting resources, so that different types of terminals (roadside equipment and vehicle-mounted equipment) can effectively coexist, and the possibility that respective systems redistribute shared spectrums according to actual conditions is reserved.

Description

technical field [0001] The present invention relates to the field of vehicle networking communication, in particular to a method and system for sharing spectrum by terminals (including roadside equipment and vehicle terminals) realized by using LTE-V2X specifications. Background technique [0002] In order to improve the safety and intelligence of the transportation system, the concept of intelligent transportation system is gradually emerging. Intelligent transportation can use the new generation of communication networks and data processing capabilities to improve the overall efficiency of the existing transportation system, reduce energy loss, and increase the safety and convenience of transportation. [0003] V2X (vehicle-to-everything) is the key to realizing intelligent transportation. It refers to the information exchange between vehicles and the outside world, and is a general term for a series of vehicle communication technologies. It uses radio frequency identific...
