Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for simulating multiple user equipments (UEs) connecting to a base station result in inefficient power allocation, leading to resource waste and inadequate consideration of individual UE service requirements.
Innovation Solution
A power allocation method that calculates and adjusts transmission power for each UE based on channel-specific priorities, ensuring the sum of transmission powers does not exceed the maximum and meets individual UE requirements, using formulas that incorporate path loss and closed loop power control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If maximum power is allocated equally among each UE, then power allocation is simple, but service requirements are not met
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different UEs based on their service requirements. Each UE is categorized into priority groups (e.g., high priority for URLLC, medium for eMBB, low for mMTC), and power is allocated differently to each priority group. This ensures that UEs with higher service requirements receive adequate power while maintaining a structured allocation approach.
Solution Approach 2:
The patent changes the power allocation parameter from equal distribution to priority-based distribution. By introducing priority coefficients (e.g., α1, α2, α3 for different priority groups) that modify the base power allocation, the system dynamically adjusts power distribution to meet varying service requirements while maintaining mathematical tractability.
2Power
If time division is used for maximum power transmission, then each UE can transmit with maximum power, but uplink resources are wasted and system performance is reduced
Solution Approach 1:
The patent merges multiple UEs' transmissions in the same time-frequency resources by implementing power domain multiplexing. Instead of separating UEs in time (TDMA), the patent allows simultaneous transmission by carefully controlling power levels based on priority, enabling better resource utilization while maintaining acceptable performance for each UE.
Solution Approach 2:
The patent introduces dynamic power allocation where power levels are adjusted in real-time based on channel conditions, UE priorities, and interference levels. The base station dynamically calculates optimal power values for each UE, allowing the system to adapt to changing conditions and maximize overall performance rather than using static time-division approaches.
3Adaptability or versatility
If a single device simulates multiple UEs, then connection tests can be conducted, but power must be shared among UEs leading to inefficient allocation
Solution Approach 1:
The patent segments the power allocation process into distinct priority groups (high, medium, low priority UEs). Each group receives power according to its specific service requirements, allowing the single testing device to efficiently simulate multiple UEs with different characteristics without wasting power on low-priority transmissions when high-priority UEs need service.
