RF Transmission Scheduling for Periodic Interference in IoT UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Repetitive mechanical or electrical activity in user equipment (UE) devices creates oscillations in radio frequency (RF) conditions, leading to inefficiencies in data transmission and reduced battery life in machine-type communication (MTC) or Internet of Things (IoT) devices.
Innovation Solution
Optimize communication by monitoring the periodicity of repetitive mechanical or electrical activity at the UE, and schedule data transmission during periods of favorable RF conditions to improve data efficiency and battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data transmission is performed continuously in MTC devices, then communication reliability is maintained, but battery life is reduced due to repetitive mechanical or electrical activity creating oscillations in RF conditions
Solution Approach 1:
The patent applies periodic action by scheduling data transmissions to occur only during favorable RF conditions rather than continuously. The base station monitors RF conditions and identifies periodic patterns, then transmits data only during favorable periods, creating a periodic transmission schedule that aligns with the oscillating RF conditions. This resolves the contradiction by maintaining communication reliability during favorable periods while extending battery life through reduced transmission activity during unfavorable periods.
Solution Approach 2:
The patent applies preliminary action by having the base station monitor and predict RF condition patterns in advance before actual data transmission occurs. The base station identifies favorable RF conditions ahead of time and schedules transmissions accordingly, allowing the system to proactively align transmissions with optimal conditions rather than reacting after conditions deteriorate. This ensures communication reliability is maintained while optimizing battery life.
2Productivity
If data transmission is scheduled during favorable RF conditions based on monitored periodicity, then data efficiency is improved, but system complexity increases due to monitoring and scheduling mechanisms
Solution Approach 1:
The patent applies self-service by having the base station autonomously monitor RF conditions, identify periodic patterns, and schedule transmissions without requiring complex coordination with the UE. The base station independently performs all monitoring and scheduling functions based on its observations of the RF environment, simplifying the overall system architecture while improving data efficiency. This resolves the contradiction by centralizing the complexity in a single entity (the base station) rather than distributing it across multiple devices.

AI summary
Many environments or operational conditions create repetitive radio frequency (RF) interference conditions resulting from repetitive mechanical or electrical activity. This activity may create oscillations in the RF conditions between an MTC UE and a serving base station. Aspects of the present invention are directed to improving data efficiency and battery life by optimizing communication based on a detected periodicity of repetitive mechanical or electrical activity at the UE by monitoring the oscillations of at least one RF condition between the MTC UE and the base station, and scheduling communication between the UE and the network during periods associated with favorable radio conditions.
