Mobile Station Energy Status Feedback for Wireless Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems do not efficiently manage energy saving at mobile stations, particularly when network nodes operate in discontinuous transmission mode, leading to increased energy consumption and reduced battery life, as existing methods either focus on network-side energy savings or do not account for the mobile station's energy status.
Innovation Solution
The mobile station actively communicates its energy status to the network node, allowing the network to configure appropriate parameters for energy-saving operations, such as reducing monitoring frequency or disabling unnecessary operations, thereby prioritizing essential functions like emergency calls and extending battery life.

Engineering Contradiction Analysis
1Use of energy by stationary object
If network nodes operate in discontinuous transmission mode to save network energy, then network energy consumption is reduced, but mobile station energy consumption increases
Solution Approach 1:
The mobile station feeds back its energy status (battery level) to the network node, enabling the network to adapt its transmission mode based on the mobile station's energy conditions. This feedback mechanism allows the system to balance network energy saving with mobile station energy consumption by adjusting monitoring requirements and transmission parameters according to the mobile station's reported energy status.
2Reliability
If mobile station monitors network nodes frequently to maintain communication quality, then communication reliability is improved, but mobile station energy consumption increases
Solution Approach 1:
The monitoring frequency and communication parameters are dynamically adjusted based on the mobile station's energy status. When energy levels are high, the mobile station can monitor more frequently to maintain high communication reliability. When energy levels are low, the monitoring frequency is reduced to conserve energy, accepting potentially lower reliability. This dynamic adaptation resolves the contradiction by making both reliability and energy consumption variable rather than fixed.
3Use of energy by moving object
If mobile station reduces monitoring frequency to save energy, then mobile station energy consumption is reduced, but communication reliability deteriorates
Solution Approach 1:
The system changes multiple parameters simultaneously based on energy status, not just monitoring frequency. These parameters include transmission power levels, resource allocation, modulation schemes, and buffer management. By coordinating changes across multiple parameters, the system can maintain communication reliability even when monitoring frequency is reduced, thus resolving the contradiction between energy saving and reliability maintenance.
