Problems solved by technology
However, in recent years, the explosive growth of the number of vehicles has caused more and more problems. Traffic accidents and traffic jams have seriously affected traffic safety.
At present, most of the work is still post-processing (such as calling the police after a car collision, and then processing), and the safety monitoring and early warning work is still lacking. Therefore, the development of wireless communication technology between vehicles and the construction of intelligent transportation systems have become research in the field of information. hotspot

Embodiment approach
[0053] In a specific implementation, the configuration of the mode3 resource pool in step S103 above can be implemented in a variety of ways, one of which is an optional implementation manner, including:
[0054] S1031. Divide the third-mode vehicle terminals in the cell into central users and edge users according to preset rules;
[0055] S1032. Configure the remaining available resources as the third mode resource pool used by the third mode vehicle terminal in the cell; wherein, the central user uses all the frequency band resources of the third mode resource pool, and the edge user uses the third mode The resource pool has some frequency band resources, and the frequency band resources used by the edge users in the cell do not overlap with the frequency band resources of the third mode resource pool configured by the edge users of the adjacent cells.
[0056] Specifically: first divide each cell user into edge users and central users, such as figure 2 shown.
[0057] Ac...

Embodiments of the present invention relate to a method and device for configuring a V2X resource pool. In the method, the fourth resource can be firstly configured in the available resources according to the location of the vehicle terminal, the resource configuration mode (mode4 or mode3) of the vehicle terminal, and the RRC state. The resource pool of the fourth mode used by the vehicle terminal of the third mode, and then configure the special resource pool, and finally configure the remaining resources as the resource pool of the third mode used by the vehicle terminal of the third mode, so that the three are orthogonal in the frequency domain. , so as to meet the requirements for vehicle terminal resource pool configuration for different scenarios, different terminal modes and different scenarios, and perform more reasonable configuration management on system resources.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a V2X resource pool configuration method and device. Background technique [0002] With the rapid development of modern automobile industry technology, the automobile industry has gradually become one of the pillar industries that promote the development of the entire social economy. The increase in the number of cars has brought a lot of convenience to people's production and life, promoted the improvement of productivity, and greatly improved people's travel environment. However, in recent years, the explosive growth of the number of vehicles has caused more and more problems. Traffic accidents and traffic jams have seriously affected traffic safety. At present, most of the work is still post-processing (such as calling the police after a car collision, and then processing), and the safety monitoring and early warning work is still lacking. T...
