Transmission Power Dependent Resource Reservation Protocol
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In advanced networks like 5G, vehicle-to-everything (V2X) services face challenges in managing resource reservations efficiently, leading to unnecessary network load due to greedy User Equipment (UE) devices reserving more resources than needed, causing congestion.
Innovation Solution
A transmission power-dependent resource reservation protocol that limits reserved resources based on the transmission power level of UE devices, allowing for dynamic allocation of resources and adjustment of reservation periods to optimize network usage and prevent congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If User Equipment (UE) devices reserve more resources to ensure adequate transmission capacity, then the reliability of communication is improved, but network congestion increases and overall network performance deteriorates
Solution Approach 1:
The patent implements dynamic resource reservation where the reservation period and amount of resources are adjusted based on current transmission power levels and network conditions. Instead of static over-reservation, UE devices dynamically adapt their resource reservations to match actual needs, resolving the contradiction between ensuring communication reliability and maintaining network performance.
Solution Approach 2:
The patent changes the parameter of resource reservation amount based on transmission power level. UE devices with lower transmission power (indicating better channel conditions or lower data requirements) reserve fewer resources, while those with higher transmission power reserve more. This parameter-based differentiation allows reliable communication for all devices while optimizing overall network resource utilization and preventing congestion.
2Reliability
If UE devices reserve resources greedily to ensure adequate transmission capacity, then the reliability of communication is improved, but the network load increases causing congestion
Solution Approach 1:
The patent applies local quality by differentiating resource reservation policies based on individual UE device characteristics, specifically transmission power level. Each UE device receives a customized resource reservation allocation appropriate to its specific needs rather than a uniform greedy reservation policy. This ensures each device achieves reliable communication while the aggregate network load is optimized.
Solution Approach 2:
The patent moves from excessive action (greedy resource reservation by all devices) to partial action (proportional resource reservation based on transmission power). UE devices reserve resources partially according to their actual requirements rather than maximally, which maintains communication reliability for each device while significantly reducing overall network load and preventing congestion.
3Device complexity
If a fixed resource reservation policy is implemented, then the device complexity is reduced, but the adaptability to different network conditions and transmission power levels deteriorates
Solution Approach 1:
The patent implements self-service where UE devices automatically determine their own resource reservation parameters based on their transmission power level and network conditions. Each device independently calculates appropriate resource reservations without requiring complex centralized control or sophisticated negotiation protocols. This maintains relatively simple device complexity while achieving high adaptability to different network conditions through autonomous decision-making.
