Resource pool determining method and related device

Abstract

The invention discloses a resource pool determining method and a related device. In the prior art, in an area without NR network coverage, the next generation of wireless access-internet of vehicle NR-V2X terminal lacks network accurate configuration and has low selection accuracy for the resource pool, consequently, the LTE network communication may be interfered. The invention solves the technical problem in the prior art. The method comprises the steps that the next generation of wireless access-internet of things NR-V2X terminal receives auxiliary information sent by a LTE-internet of things LTE-V2X terminal; the NR-V2X terminal determines, based on the auxiliary information, that a sending resource pool that is used for direct communication with the LTE-V2X terminal is a first resource pool; and the NR-V2X terminal directly communicates with the LET-V2X terminal in the communication range of the NR-V2X terminal by using the first resource pool.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method for determining a resource pool and related equipment. Background technique [0002] The V2V (Vehicle to Vehicle, Internet of Vehicles) technology has realized vehicle-to-vehicle interconnection based on the LTE (LongTerm Evolution) network in Rel-14. Vehicles can communicate with each other through the LTE Uu interface. Can communicate directly through the PC-5 interface. [0003] V2X (Vehicle to Everything, Internet of Vehicles) technology. In Rel-14, this technology also realizes the mutual communication between vehicles and pedestrians, and the mutual communication between vehicles and roadside equipment on the basis of the above-mentioned V2V technology. [0004] In the future NR (Next generation RAT, next generation wireless access) system, V2X related technologies will continue to evolve. Then there will be a problem of how the LTE-V2X terminal based on th...

Problems solved by technology

[0005] In the actual communication process, because the NR-V2X terminal is offline, it may not be possible to obtain a more accurate configuration of the network, only pre-configuration can be used, and the pre-configuration is a pool containing all the transmission resources that the NR-V2X terminal can use The resource pool list, the terminal independently selects the resource pool from the resource pool list, which can realize the intercommunication between NR-V2X terminals and LTE-V2X terminals, but the transmission resource pool selected based on pre-configuration may not avoid conflicts with the current LTE network resources , and then interfere with the communication of the LTE network

Therefore, in areas without NR network coverage in the prior art, due to the lack of precise configuration of the network for NR-V2X terminals, the accuracy of resource pool selection is low, which may cause technical problems that may interfere with LTE network communications
