Dynamic Band Scheduling for Multi-Band UE Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems inadequately assign mobile user equipment (UE) devices to bands with suitable properties, leading to suboptimal service quality, spectrum inefficiency, and increased costs due to differing frequencies and device constraints.
Innovation Solution
A radio access network dynamically assigns radio resources across multiple bands based on the specific constraints and conditions of UE devices and the properties of available bands, optimizing the match between band characteristics and device needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile user equipment devices are assigned to bands with suitable properties, then service quality is improved, but device complexity increases due to multi-band operation requirements
Solution Approach 1:
The system dynamically assigns UE devices to different frequency bands based on real-time conditions and device constraints. The band assignment is not static but adapts to changing network conditions, traffic patterns, and device capabilities, allowing optimal service quality without requiring devices to permanently support all bands
Solution Approach 2:
Different frequency bands with distinct properties (low frequency for coverage, high frequency for capacity) are assigned to different UE devices based on their specific constraints and service requirements. Each device receives a locally optimized band assignment rather than a uniform system-wide assignment
2Productivity
If multiple frequency bands are used for different services, then spectrum efficiency is improved, but system complexity increases due to managing multiple bands with different properties
Solution Approach 1:
The network system is designed to universally manage multiple frequency bands with different properties through a unified band assignment mechanism. The same core network infrastructure and control procedures handle both low-frequency and high-frequency bands, avoiding the need for separate specialized systems for each band type
Solution Approach 2:
The system changes operational parameters (frequency band assignment) based on service requirements and network conditions. Different bands are selected and configured according to specific service needs, allowing flexible adaptation without hardcoding separate systems for each service type
3Use of energy by moving object
If UE devices operate on bands that best meet their requirements, then battery life is extended, but measurement precision requirements increase to assess band suitability
Solution Approach 1:
The system uses feedback from UE devices about their operating conditions, signal quality, and power consumption to continuously refine band assignments. This feedback mechanism enables the network to learn which band assignments optimize battery life for different devices and conditions, reducing the need for overly complex measurement requirements
