UE Discovery Signal Resource Allocation via Dynamic Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current direct discovery signal communication methods in communication devices face challenges in efficiently managing radio resources, leading to suboptimal power consumption and processing time, especially when multiple devices share resources and require dynamic allocation.
Innovation Solution
User equipment (UE) selects and updates target operating radio resources based on calculated loading of discovery radio resources, allowing for adaptive resource management to optimize power usage and processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If contention-based resource allocation is used for discovery signals, then power consumption and processing time are reduced, but radio resource management efficiency deteriorates due to random resource selection and potential conflicts
Solution Approach 1:
The patent implements dynamic resource allocation where the base station continuously monitors discovery signal transmissions and dynamically assigns specific resource blocks to different UEs based on current network conditions, traffic patterns, and interference levels. This dynamic approach replaces static random selection with adaptive resource management that optimizes both power efficiency and resource utilization
Solution Approach 2:
The system incorporates feedback mechanisms where UEs report channel quality indicators and resource usage status to the base station, which then adjusts resource allocation decisions accordingly. This closed-loop feedback enables the network to maintain high resource management efficiency while allowing UEs to operate in power-efficient modes by relying on centralized coordination rather than continuous local decision-making
2Use of energy by moving object
If multiple Tx DUEs share the same resource blocks to deliver discovery signals, then power consumption is reduced, but interference and resource conflict increase
Solution Approach 1:
The patent segments the discovery signal resource pool into multiple orthogonal resource blocks (time-frequency slots) that are systematically allocated to different UEs. This segmentation allows multiple Tx DUEs to transmit simultaneously on different resource blocks without causing interference, while still enabling power-efficient operation compared to dedicated high-power channels for each UE
Solution Approach 2:
The system dynamically changes resource allocation parameters (resource block assignments, transmission power levels, time-frequency positions) based on network conditions. When multiple UEs need to transmit discovery signals, the base station adjusts these parameters to orthogonalize their transmissions, eliminating interference while maintaining the power efficiency benefits of shared resource usage
3Productivity
If dynamic resource allocation is implemented, then radio resource management efficiency is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent introduces the base station as an intermediary that centralizes the complex resource allocation decisions. Instead of requiring each UE to independently perform complex resource management and conflict resolution, the base station acts as a mediator that receives simple reports from UEs and returns optimized resource assignments, thereby achieving high resource management efficiency while keeping individual UE processing overhead low
Solution Approach 2:
The system enables UEs to self-configure their discovery signal transmissions based on pre-configured parameters and simple rules provided by the base station. Once the base station provides resource allocation directives, UEs can autonomously configure their transmitters without requiring complex real-time processing, thus achieving efficient resource management with minimal device complexity

AI summary
A method of controlling discovery signal communication of a user equipment (UE) and a UE using the same is disclosed. The method comprises steps of selecting a target operating radio resource associated with the discovery signal communication among a plurality of discovery radio resources to transmit at least one discovery signal of the UE, and updating the target operating radio resource by the UE based on a loading of the plurality of discovery radio resources calculated by the UE.
