Sidelink RRM Reporting for Reliable Mobility and Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies, such as 5G NR, lack comprehensive radio resource management (RRM) procedures for sidelink communications, which are crucial for device-to-device interactions like vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, particularly in scenarios involving idle or out-of-coverage UEs.
Innovation Solution
Implementing RRM procedures for sidelink communications, including configurations for measuring and reporting signal parameters, resource allocation modes, and network-controlled mobility, to facilitate SLRB reconfiguration, resource pool optimization, and carrier aggregation management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RRM procedures are implemented for sidelink communications, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The RRM procedure is segmented into distinct functional components: configuration reception (from base station or peer device), signal measurement (of sidelink reference signals), and report transmission (to base station or peer device). This segmentation allows each component to be implemented independently, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The patent implements feedback mechanisms where measurement reports are transmitted to the base station or peer device based on configured conditions. This feedback enables dynamic RRM adjustments and mobility management, improving communication reliability in idle and out-of-coverage scenarios without requiring overly complex local decision-making at the UE.
2Adaptability or versatility
If comprehensive RRM procedures are implemented, then mobility management capability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent enables UEs to perform RRM measurements and report signal parameters autonomously without continuous network intervention. The UE receives initial configuration and then independently performs measurements, selects appropriate reporting triggers, and transmits reports based on configured conditions, reducing operational complexity while maintaining mobility management capabilities.
Solution Approach 2:
The patent supports flexible configuration of measurement and reporting parameters (such as measurement identities, reporting triggers, and periodicity) that can be adapted to different operational scenarios. This parameter flexibility allows the same RRM procedure to handle various mobility situations without requiring complex procedural changes, improving ease of operation.
3Productivity
If signal measurement and reporting is enabled, then resource allocation efficiency is improved, but use of energy increases
Solution Approach 1:
The patent implements periodic measurement and reporting configurations where UEs perform signal measurements at predetermined intervals or triggered by specific events rather than continuously. This periodic action reduces energy consumption compared to continuous monitoring while still providing sufficient information for efficient resource allocation and mobility management decisions.
Solution Approach 2:
The patent allows selective measurement of specific signal parameters (such as reference signal received power or quality) based on configuration rather than measuring all possible parameters. This partial action approach reduces the energy burden on the UE while maintaining the necessary information for resource allocation efficiency, avoiding the excessive action of comprehensive continuous measurement.
