Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high energy consumption of 5G base stations due to the increased number of antennas, which is a significant operational expense, necessitates a method to reduce energy consumption while maintaining communication quality.
Innovation Solution
A base station energy saving method that dynamically adjusts the working state by entering different energy saving modes, such as microsleep, light sleep, and deep sleep, by selectively disabling signal transmission and reception based on load conditions and traffic sensitivity, and indicates these modes to the terminal device using various signaling methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of antennas is increased to achieve beamforming and support more users, then communication quality and coverage are improved, but energy consumption increases significantly
Solution Approach 1:
The patent applies dynamics by making the base station's working state adjustable and flexible. The base station can dynamically switch between different working states (normal mode, energy saving mode, deep sleep mode) based on real-time load conditions and traffic sensitivity, rather than operating in a fixed high-power state. This dynamic adaptation allows the system to maintain communication quality when needed while reducing energy consumption during low-traffic periods.
Solution Approach 2:
The patent changes operational parameters by adjusting the base station's working state parameters based on load conditions. By modifying parameters such as signal transmission power, antenna activation status, and processing intensity according to real-time traffic conditions, the system achieves optimal balance between communication quality and energy consumption without requiring physical hardware changes.
2Reliability
If the base station operates in normal mode to ensure communication quality, then signal transmission and reception are maintained, but energy consumption remains high
Solution Approach 1:
The patent implements periodic action by having the base station periodically assess its load conditions and traffic sensitivity, then switch between normal mode and energy saving modes accordingly. This periodic evaluation and state transition allows the base station to maintain high communication quality during peak periods while reducing energy consumption during off-peak periods, creating a rhythmic pattern of high and low power states that balances performance and efficiency.
Solution Approach 2:
The patent extracts the essential function of signal transmission from the base station's continuous operation. By identifying and maintaining only the critical signal processing functions during energy saving mode while suspending non-essential operations, the system preserves communication quality for active users while eliminating unnecessary energy consumption from idle or low-priority functions.
3Use of energy by moving object
If the base station enters energy saving mode to reduce energy consumption, then power usage is reduced, but communication quality may be compromised
Solution Approach 1:
The patent applies feedback by continuously monitoring load conditions and traffic sensitivity, then using this information to determine the appropriate working state. The system receives feedback about actual communication demands and adjusts its power state accordingly, ensuring that energy saving mode is only entered when communication quality requirements are still met with reduced power, thus preventing quality degradation while achieving energy savings.
Solution Approach 2:
The patent makes the transition between working states dynamic and adaptive rather than static. The base station continuously evaluates current conditions and switches between normal mode, energy saving mode, and deep sleep mode in real-time, allowing it to respond to changing communication demands. This dynamic behavior ensures communication quality is maintained during high-traffic periods while maximizing energy savings during low-traffic periods.
4Use of energy by moving object
If signal processing is optimized to reduce energy consumption, then processing operations are reduced, but communication reliability may be affected
Solution Approach 1:
The patent applies partial action by performing only the necessary signal processing operations required to maintain communication reliability during energy saving mode, rather than executing the full range of processing operations available in normal mode. By identifying and executing only the critical subset of processing functions needed for reliable communication, the system reduces energy consumption while preserving essential communication quality.
