Power Control for Multi-Registration Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-registration terminals face data transmission losses due to limitations in total transmit power, as they need to manage multiple network registrations and uplink signals across different radio access technologies, leading to inefficiencies in power allocation and potential data loss.
Innovation Solution
A power control method that involves reporting power allocation information and selecting target identifications for uplink signal transmission based on power priorities, and determining transmit powers using maximum power reduction to optimize power usage across multiple identifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal transmits multiple uplink signals using multiple terminal identifications simultaneously, then the data transmission capability is improved, but the total transmit power is exceeded causing some uplink signals to be unable to be transmitted
Solution Approach 1:
The patent dynamically adjusts the transmit power parameter for different uplink signals based on their priority levels. High-priority signals maintain their allocated power, while low-priority signals have their power reduced or transmission suspended when total power would be exceeded, thereby resolving the contradiction between maintaining high data transmission capability and staying within power limits
Solution Approach 2:
The patent applies different power control strategies to different uplink signals based on their local characteristics (priority levels). Instead of uniform power allocation, each signal receives differentiated power treatment - high-priority signals get full power support while low-priority signals receive reduced power or are suspended, optimizing the overall power utilization
2Ease of operation
If the terminal allocates equal power to all uplink signals, then the power allocation is simple, but the transmission efficiency is reduced due to power limitations
Solution Approach 1:
The patent changes the power allocation parameter from equal distribution to priority-based distribution. The network device configures different power values for different uplink signals according to their priority, and the terminal adjusts transmit power dynamically based on these configurations, thereby improving transmission efficiency while maintaining manageable operational complexity through standardized power control procedures
