Downlink Receiver Type Selection for UE Power and Throughput Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face challenges in managing power consumption and network performance due to varying channel conditions, with existing UE receiver configuration selection methods either increasing power consumption or reducing throughput and spectral efficiency.
Innovation Solution
A network node dynamically selects receiver types for different portions of a downlink communication based on channel conditions, power metrics, and performance metrics, instructing UEs to use higher power-consuming configurations only for poor channel resources and lower power configurations for better resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If higher power-consuming receiver configurations are used for all downlink communications, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies local quality by selecting different receiver configurations for different portions of downlink communication based on channel conditions. Instead of using a uniform high-power configuration for all transmissions, the network node dynamically selects receiver types tailored to specific channel segments, using higher power-consuming configurations only where necessary for poor channel resources and lower power configurations for better resources.
Solution Approach 2:
The patent implements dynamics through dynamic receiver type selection that adapts to varying channel conditions. The network node continuously monitors channel quality and adjusts the receiver configuration in real-time, transitioning between different receiver types based on current transmission conditions rather than maintaining a static configuration.
2Use of energy by moving object
If lower power receiver configurations are used for all downlink communications, then power consumption is reduced, but throughput and spectral efficiency decrease
Solution Approach 1:
The patent applies local quality by matching receiver configuration power levels to the specific requirements of each channel segment. Lower power configurations are used only for portions of downlink communication with good channel conditions, while higher power configurations are deployed for segments requiring more robust reception, optimizing the balance between power consumption and performance.
Solution Approach 2:
The patent implements dynamics through adaptive selection of receiver configurations that respond to changing channel conditions. The system dynamically adjusts between low-power and high-power receiver modes based on real-time channel quality assessments, ensuring throughput and spectral efficiency are maintained when conditions permit while reducing power consumption when possible.
3Use of energy by moving object
If dynamic receiver type selection is implemented, then power consumption is optimized, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously select appropriate receiver configurations from a set of supported types based on received downlink communications and channel conditions. The UE independently manages its receiver type selection without requiring complex external control, reducing the complexity burden on the network node while achieving power optimization.
Solution Approach 2:
The patent implements preliminary action by having the UE pre-configure and report its supported receiver types to the network node before actual downlink communication begins. This advance preparation allows the network node to make informed selection decisions without requiring complex real-time analysis of all possible configuration combinations during active transmission.
