Problems solved by technology

[0004] However, as the number of users with autonomous resource selection increases (such as vehicle congestion scenarios), resource competition among user equipment intensifies, resulting in an increase in the probability of resource conflicts between user equipment (that is, multiple selections of the same time-frequency resources)
Once the conflict occurs, the user's data cannot be received reliably, which may have an adverse impact on driving safety.

Abstract

The present invention relates to a method for realizing reliable transmission of messages, user equipment and a base station. By acquiring load information of resource pools and reporting them to the base station, the base station can know the load rate in each resource pool in time, so that the load rate of each resource pool can be obtained according to each resource pool. Adjust the resources in each resource pool to reduce resource conflicts.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, user equipment and base station for achieving reliable message transmission. Background technique [0002] V2X (Vehicle to X) is the information exchange between the car and the outside world, and is the key technology of the future intelligent transportation system. V2X was approved at the 3GPP RAN#68 meeting to establish a project, mainly researching vehicle data transmission solutions based on 3GPP communication protocols. V2X communication includes V2V communication (vehicle-to-vehicle communication), V2I communication (vehicle-to-roadside infrastructure communication), and V2P communication (vehicle-to-pedestrian communication). V2X applications will improve driving safety, reduce congestion and vehicle energy consumption, improve traffic efficiency and in-car entertainment information. [0003] There are two resource scheduling methods for V2X commun...
