Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication terminals face high power consumption and ambiguity in signal detection due to inconsistent cell coverage and the need to monitor multiple signals, leading to increased system complexity.
Innovation Solution
A method and apparatus that utilize a single signal or channel with dual functions of keeping the terminal alive and waking it up, allowing the terminal to determine its operating state based on inherent measurement resources, reducing the need for separate wake-up and keep-alive signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal monitors a wake-up signal and a keep-alive signal separately to determine operating state, then the terminal can accurately distinguish between no signal transmission and insufficient coverage, but the system complexity increases due to needing to detect two signals
Solution Approach 1:
The patent combines the wake-up signal and keep-alive signal into a single signal transmission mechanism. The network side transmits one signal that serves both purposes: indicating wake-up and maintaining keep-alive functionality. This merging eliminates the need for the terminal to monitor two separate signals, reducing system complexity while maintaining reliable signal detection through alternative mechanisms such as reference signals or downlink shared channel transmissions.
Solution Approach 2:
The patent implements a universal signal that performs multiple functions simultaneously. The single transmitted signal serves as both a wake-up indicator and a keep-alive mechanism, allowing the terminal to determine its operating state without requiring separate dedicated signals for each function. This multi-functionality approach reduces the number of signals the terminal must monitor while preserving the ability to accurately distinguish between different transmission scenarios.
2Reliability
If a terminal monitors multiple signals periodically to determine operating state, then the terminal can accurately determine when to wake up, but the power consumption increases due to continuous monitoring requirements
Solution Approach 1:
The patent merges the wake-up signal monitoring and keep-alive signal monitoring into a single monitoring operation. The terminal only needs to monitor one signal type periodically, which reduces the cumulative power consumption associated with monitoring multiple separate signals while maintaining the ability to accurately determine operating state through the combined functionality of the unified signal.
Solution Approach 2:
The patent employs periodic monitoring of the unified signal at optimized intervals, allowing the terminal to remain in a low-power dormant state between monitoring periods. By consolidating the monitoring requirements into a single periodic check rather than multiple separate periodic checks, the terminal reduces its overall power consumption while still maintaining reliable detection capability when the signal is transmitted.
3Power
If the specific signal transmission power is limited by network constraints, then the network can control resource allocation, but the signal may not be consistent with cell coverage causing detection ambiguity
Solution Approach 1:
The patent introduces reference signals or downlink shared channel transmissions as intermediary signals that accompany or replace the specific wake-up/keep-alive signal. These intermediary signals have established coverage characteristics that are consistent with cell coverage, allowing the terminal to use them for reliable detection and coverage assessment. The intermediary acts as a mediator between the limited-power specific signal and the terminal's detection requirements, ensuring coverage consistency without requiring high transmission power.
