Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for reducing energy consumption in base stations by putting them in a dormant state do not efficiently manage the transition from dormancy to active communication, leading to inefficiencies in awakening processes.
Innovation Solution
A method and apparatus for awakening network devices by configuring user equipment with power parameter information to send awakening signals to multiple network devices, allowing them to determine channel quality and decide on activation based on signal quality thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the base station is put in a dormant state to reduce energy consumption, then energy saving is improved, but the awakening process becomes inefficient and communication readiness deteriorates
Solution Approach 1:
The network device performs preliminary actions by determining configuration information including power parameters before the UE sends the awakening signal. The base station pre-configures power parameters and readiness conditions, so when awakening is needed, the transition can occur more efficiently without full activation. This preliminary setup reduces the time and energy required for the awakening process while maintaining energy savings during dormant periods.
2Use of energy by moving object
If the base station remains in dormant state with minimal functions, then energy consumption is reduced, but channel quality assessment capability deteriorates
Solution Approach 1:
The UE acts as an intermediary that carries out channel quality assessment on behalf of the dormant base station. The UE measures the downlink channel quality and reports this information to the network device. This allows the base station to maintain dormant state with minimal energy consumption while still obtaining accurate channel quality information through the UE's measurements and reports.
Solution Approach 2:
The patent replaces the mechanical/physical mechanism of the base station actively measuring channel quality with an information-based approach where the UE performs measurements and reports results. This substitution allows the base station to remain dormant while still acquiring necessary channel quality information through digital information exchange rather than active physical measurement.
3Productivity
If the base station activates full transceiving functions upon receiving awakening signal, then communication readiness is improved, but energy waste increases during transition
Solution Approach 1:
The network device determines configuration information in advance, including power parameters and activation conditions. When the UE sends an awakening signal, the base station can quickly transition to active state because the configuration is already prepared. This preliminary preparation reduces the transition time and associated energy waste while ensuring communication readiness is achieved efficiently.
Solution Approach 2:
The base station implements dynamic state transition based on the awakening signal and configuration information. Rather than constantly maintaining full transceiving functions, the system dynamically switches between dormant and active states based on actual communication needs. This dynamic approach reduces energy waste during transitions while maintaining communication readiness when required.
