Solution Overview
Problem
Cellular communications between a base station and user equipment are degraded by path loss, noise, and interference, and existing diversity receivers increase power consumption, reducing active or talk time without effectively managing resources to maintain network performance.
Innovation Solution
A cellular transceiver with multiple diversity branch receivers that includes a windup detector and a receiver selector to adjust the number of active receivers based on channel conditions, signal quality, and resource requirements, enabling or disabling receivers to optimize power usage and maintain performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple diversity branch receivers are used to improve communication performance, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic reconfiguration of the diversity receiver system by selectively activating or deactivating individual diversity branch receivers based on real-time channel conditions. The system transitions from a static configuration where all receivers remain active to a dynamic configuration where the number of active receivers adapts to current communication needs, thereby reducing power consumption when full diversity is not required while maintaining reliability when needed.
Solution Approach 2:
The system changes the operational parameter of the receiver system by adjusting the number of active diversity branch receivers. This parameter change allows the system to operate at different power levels depending on channel conditions, transforming the fixed-power consumption model into a variable-power model that optimizes energy usage while maintaining communication performance.
2Reliability
If multiple diversity branch receivers are activated to maintain network performance, then reliability is improved, but talk time is reduced
Solution Approach 1:
The system dynamically adjusts the number of active diversity branch receivers based on channel conditions, enabling the device to extend battery life during periods of good signal quality while maintaining adequate network performance when needed. This dynamic adaptation directly addresses the talk time limitation by reducing power consumption during normal operation.
Solution Approach 2:
The system employs periodic assessment of channel conditions and periodically reconfigures the number of active receivers accordingly. This periodic action allows the system to maintain network performance during critical periods while conserving battery power during less demanding periods, thereby extending overall talk time.
3Use of energy by moving object
If diversity branch receivers are managed carefully to reduce power consumption, then energy efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements self-service through automatic channel condition assessment and autonomous decision-making algorithms that determine which diversity branch receivers should be active. This self-service mechanism eliminates the need for complex manual resource management while achieving optimal power consumption, as the system automatically adapts to changing conditions without user intervention.
Solution Approach 2:
The system incorporates feedback loops that continuously monitor channel conditions and adjust the number of active receivers accordingly. This feedback mechanism simplifies resource management by using real-time performance data to automatically optimize power consumption, replacing complex manual management with an automated closed-loop control system.
