UE Transceiver Segmentation for RRC Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently managing power consumption and preventing communication abnormalities in user equipment (UE) during discontinuous reception (DRX) scenarios and RRC connected states.
Innovation Solution
The implementation of a method where a UE with a first and second transceiver turns off the high-power first transceiver and turns on the low-power second transceiver when in an RRC connected state and meets a preset condition, allowing the second transceiver to monitor a preset signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the UE turns off the first transceiver and turns on the second transceiver to monitor preset signal, then power consumption is reduced, but communication reliability may deteriorate
Solution Approach 1:
The transceiver system is segmented into two distinct transceivers: a first transceiver for normal high-power communication operations and a second transceiver for low-power preset signal monitoring. This segmentation allows the UE to use only the necessary transceiver based on operational requirements, reducing overall power consumption while maintaining communication reliability when needed.
Solution Approach 2:
The system dynamically switches between the first and second transceivers based on preset conditions. When the preset condition is met, the UE turns off the first transceiver and activates the second transceiver for monitoring. This dynamic adaptation allows the system to optimize power consumption in idle states while ensuring reliable communication when data transmission is required.
2Use of energy by moving object
If the UE monitors preset signal with second transceiver only, then power consumption is reduced, but detection precision may worsen
Solution Approach 1:
The second transceiver is specifically optimized for local quality in terms of power efficiency, consuming significantly less power than the first transceiver. However, it is designed with sufficient detection capability for the specific preset signals it needs to monitor. The first transceiver maintains full detection precision for comprehensive communication operations when activated.
Solution Approach 2:
The second transceiver acts as an intermediary for preliminary signal detection before full communication operations commence. It can detect preset signals with adequate precision for wake-up or indication purposes, and when detection is successful, the first transceiver is activated for high-precision comprehensive communication, thus balancing power consumption and detection precision.
