Time-Gating Controller for Wireless Receiver Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in reducing power consumption in mobile devices, leading to shorter battery life and increased costs, as existing methods do not effectively manage power usage during communication periods.
Innovation Solution
A method and apparatus that utilize a controller to regulate power consumption in wireless communication systems by receiving control signals and implementing time-gating patterns for both receivers and transmitters, allowing them to be powered down during intervals when no data is being transmitted or received, thereby conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the receiver is continuously powered on to maintain communication readiness, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The receiver is powered on and off periodically according to a time-gating pattern that aligns with expected data transmission intervals. The controller activates the receiver only during time windows when data is expected to be received, based on scheduling information from the base station, and keeps it powered off during intervals when no data is expected, thereby maintaining communication reliability while reducing power consumption.
2Use of energy by moving object
If the receiver is powered down during intervals to conserve power, then power consumption is reduced, but response time increases
Solution Approach 1:
The controller activates the receiver in advance of expected data transmission intervals based on scheduling information received from the base station. By anticipating when data will be transmitted and powering on the receiver beforehand, the system ensures immediate responsiveness when data arrives while still maintaining the receiver in a low-power state during intervals when no data is expected.
3Use of energy by moving object
If time-gating is implemented at intervals less than one radio frame, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The controller receives scheduling information as feedback from the base station indicating when data transmissions are expected. This feedback mechanism allows the controller to dynamically adjust the time-gating pattern for the receiver, powering it on only during intervals when data is expected based on the scheduling information, thereby achieving fine-grained power savings without requiring complex predetermined timing mechanisms.
