Resource selection method, apparatus, device, storage medium and program product
By eliminating RSU beacon signal resources before the vehicle enters the tunnel, the problem of positioning inaccuracy caused by collision between OBU and RSU resources is solved, ensuring that the vehicle can stably receive RSU beacon signals in the tunnel, achieving high-precision and high-reliability positioning, and improving driving safety.

AI Technical Summary
Technical Problem
In vehicle-to-everything (V2X) systems, when vehicles enter tunnels, weak or no GNSS signals can cause collisions between OBU and RSU resources, affecting positioning accuracy and reliability.
Method used
The OBU determines whether to enter the tunnel based on the RSRP measurement value and excludes time-domain resources used for RSU beacon signals from the resource pool to ensure that data transmission resources do not conflict with RSU beacon signal resources and to stably receive RSU beacon signals.
Benefits of technology
It achieves high-precision and high-reliability positioning of vehicles in tunnels, ensuring driving safety.

Abstract
The application provides a resource selection method and device, equipment, a storage medium and a program product, relates to the Internet of Vehicles technical field, and the method is applied to OBU installed on a first vehicle and includes the following steps: determining whether the first vehicle is about to enter a tunnel or has entered the tunnel according to a reference signal receiving power (RSRP) measurement value of first information or a first signal related to driving of the first vehicle; and in the case that the first vehicle is about to enter the tunnel or has entered the tunnel, excluding first time domain resources in a resource pool according to a detected first positioning reference signal and a received first beacon signal, wherein the first time domain resources are used to carry a beacon signal transmitted by a target RSU, and available resources after resource exclusion are used for data transmission. In this way, collision of transmission resources of the OBU and transmission resources of the RSU for sending the beacon signal is avoided, stable reception of the beacon signal is achieved, and positioning accuracy and reliability are improved.
