Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In non-terrestrial wireless communication networks, user equipment (UEs) with low data transmission requirements often experience energy wastage due to long-term connections, as they can tolerate delays in data transmission.
Innovation Solution
The implementation of a sleep mode for UEs in non-terrestrial networks, where processing circuitry determines and transmits parameters for alternating data transmission and sleep windows based on uplink data information, allowing UEs to conserve energy by reducing continuous connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment maintains long-term connection in NTN, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by establishing alternating sleep windows and data transmission windows for user equipment in NTN. The UE periodically wakes up during data transmission windows to communicate with the network, then returns to sleep mode during sleep windows. This periodic operation pattern allows the UE to maintain communication capability while significantly reducing energy consumption compared to continuous connection, directly resolving the contradiction between reliability and energy usage.
2Use of energy by moving object
If user equipment enters sleep mode to save energy, then energy efficiency is improved, but data transmission delay increases
Solution Approach 1:
The patent applies dynamics by making the sleep window and data transmission window durations configurable and adaptable based on UE characteristics and service requirements. The network can dynamically adjust the length of sleep windows and data transmission windows, and the number of consecutive sleep windows, to optimize the balance between energy saving and transmission delay. This dynamic adjustment capability allows the system to adapt to different scenarios, resolving the contradiction between energy efficiency and transmission delay.
3Use of energy by moving object
If sleep window length is increased to save energy, then energy consumption is reduced, but responsiveness to data transmission requests decreases
Solution Approach 1:
The patent implements parameter changes by allowing flexible configuration of multiple parameters including sleep window length, data transmission window length, and the number of consecutive sleep windows. The network can adjust these parameters based on UE data generation patterns, service requirements, and channel conditions. By changing these parameters, the system can optimize the balance between energy consumption and responsiveness, resolving the contradiction between extending sleep duration for energy saving and maintaining quick response capability.
