LTE-A Terminal Transmission Mode Selection for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE-A systems, terminals face increased power consumption due to varying operational features in different transmission modes, leading to inefficiencies in power usage across wideband and narrowband transmission modes.
Innovation Solution
A method and apparatus that determine a transmission mode by receiving capability information from the terminal, selecting between wideband and narrowband modes based on network resource conditions, and matching the selection with the terminal's capabilities to minimize power consumption, allowing the network to choose an optimal mode for reduced power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal works in both wideband and narrowband transmission modes to aggregate multiple wavebands, then the transmission capability is improved, but the power consumption increases due to complex operational features
Solution Approach 1:
The patent implements dynamic transmission mode selection where the terminal can switch between wideband and narrowband modes based on real-time network conditions and capability matching. The network determines the appropriate mode by evaluating terminal capability information and current network resource conditions, allowing the system to adapt its operational characteristics dynamically rather than being fixed in one mode
Solution Approach 2:
The patent changes the transmission mode parameter (wideband vs narrowband) based on terminal capability information and network conditions. By modifying this key operational parameter, the system optimizes power consumption while maintaining transmission capability when needed
2Adaptability or versatility
If different manufacturers adopt different terminal structures, then the adaptability is improved, but the power consumption varies and increases due to limitations of integrated circuit components
Solution Approach 1:
The patent applies local quality by evaluating specific terminal capability information related to power consumption characteristics. Instead of treating all terminals uniformly, the system assesses individual terminal structures and their specific power consumption patterns in different transmission modes, then makes targeted mode selections for each terminal based on its unique characteristics
Solution Approach 2:
The patent implements a feedback mechanism where terminal capability information including power consumption characteristics is reported to the network. The network uses this feedback to determine the appropriate transmission mode, creating a closed-loop system that continuously optimizes power consumption based on actual terminal performance data
