Sidelink Resource Selection Using Pre-Configured Transmission Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sidelink communication, when a transmission resource pool is absent in system information, remote UEs experience communication interruptions as they lack available resources for transmission.
Innovation Solution
Utilizing pre-configured transmission resources for sidelink communication when no transmission resource pool is available in system information, ensuring continuous communication between remote UEs and relay UEs or base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transmission resource pool is used for sidelink communication, then communication between remote UEs and relay UEs is enabled, but communication interruptions occur when the transmission resource pool is absent in system information
Solution Approach 1:
The patent applies preliminary action by pre-configuring transmission resources in the UE before actual communication occurs. When a transmission resource pool is absent in system information, the UE can still perform sidelink transmission using these pre-configured resources, thereby avoiding communication interruptions and ensuring continuous service.
2Reliability
If pre-configured transmission resources are used when transmission resource pool is absent, then communication interruptions are prevented, but resource allocation flexibility is reduced
Solution Approach 1:
The patent implements preliminary action by configuring transmission resources in advance within the UE. This ensures that when system information does not provide a transmission resource pool, the UE already has the necessary resources configured to maintain communication, thus preventing service interruptions while operating under constrained resource allocation conditions.

AI summary
A resource selection method and device, a user equipment, a base station, a storage medium, and a chip, relating to the technical field of communications. The method is applied to a user equipment, and comprises: in response to there being no transmission resource pool in received system information, performing sidelink transmission by means of a pre-configured transmission resource. By using the resource selection method provided by the present disclosure, when there is no transmission resource pool in system information, sidelink transmission can be performed by means of a pre-configured transmission resource, thereby avoiding interruption of communications and services of a user equipment.
