Relay UE Connection Scoring for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing data transmission and reception between Relay UE and Remote UE, particularly in determining the optimal Relay UE for data transceiving, due to limitations in resource allocation and prioritization of traffic types, leading to suboptimal performance in next-generation mobile communication systems.
Innovation Solution
A method is introduced where a Relay UE determines whether to serve a connection request from a Remote UE by calculating a score based on control information related to its current state, traffic type, and load state, and transmits this determination to the Remote UE, using a priority and weight system to select the most suitable Relay UE for data transceiving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a Relay UE serves multiple Remote UEs simultaneously, then the coverage area and connectivity are improved, but the load on the Relay UE increases leading to resource allocation inefficiency
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the scoring criteria for Relay UE selection based on current system state. The network side or Remote UEs calculate scores using parameters such as channel quality, load conditions, and traffic types, allowing the system to adapt to changing conditions and optimize resource allocation as the number of connected Remote UEs varies
Solution Approach 2:
The patent implements dynamics through the dynamic scoring mechanism where Relay UE suitability is not fixed but continuously evaluated. The score changes based on real-time parameters including current load, channel state, and traffic requirements, enabling the system to dynamically adjust which Remote UEs connect to which Relay UEs to maintain optimal resource allocation efficiency
2Device complexity
If the Relay UE selection is based on simple criteria, then the device complexity and processing overhead are reduced, but the performance and energy efficiency are suboptimal
Solution Approach 1:
The patent applies feedback through the scoring mechanism where the network side or Remote UEs evaluate multiple parameters including channel quality, load conditions, and traffic types to calculate a comprehensive score. This feedback-based approach allows the system to make informed selection decisions that optimize data transceiving efficiency without requiring complex device modifications, as the scoring can be performed by the network or through standardized procedures
3Ease of operation
If the Relay UE does not consider traffic type priority in selection, then the ease of operation is improved, but the quality of service for different traffic types deteriorates
Solution Approach 1:
The patent applies parameter changes by incorporating traffic type priority as a specific parameter in the scoring mechanism. When evaluating potential Relay UEs, the system considers the priority level of the traffic that needs to be transmitted, allowing high-priority traffic to be routed through more suitable Relay UEs. This maintains ease of operation through automated scoring while improving quality of service through traffic-aware selection
