Radio Network Bandwidth Interval Control for UE-Aware Power Savings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks lack an automated and adaptive mechanism to adjust Instantaneous Bandwidth (IBW) based on the usage and position of User Equipments (UEs), leading to inefficient power consumption and resource allocation.
Innovation Solution
A method and system for a radio network node to dynamically adjust IBW based on the current state of resource usage and UE positions, using prediction and reinforcement learning to optimize bandwidth allocation while considering Quality of Service (QoS).
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bandwidth interval is increased to serve more UEs, then the network capacity and coverage are improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic bandwidth adjustment by enabling the radio network node to automatically change the bandwidth interval based on real-time UE positions and resource usage conditions. This transforms the static bandwidth configuration into a dynamic parameter that adapts to changing network conditions, allowing the system to optimize between capacity and power consumption continuously
Solution Approach 2:
The patent changes the bandwidth interval parameter based on measured conditions. By monitoring UE positions and resource usage, the system adjusts the bandwidth interval parameter to match actual demand, reducing it when fewer UEs are present to save power while maintaining sufficient capacity when needed
2Use of energy by moving object
If the bandwidth interval is decreased to reduce power consumption, then energy efficiency is improved, but the network capacity and ability to serve UEs deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the radio network node continuously monitors UE positions and resource usage conditions, then uses this feedback information to adjust the bandwidth interval accordingly. This closed-loop control ensures that bandwidth is reduced only when conditions permit, maintaining network capacity when UEs are present while saving power when they are absent
Solution Approach 2:
The system enables the radio network node to automatically adjust its own bandwidth configuration based on monitored conditions, without requiring external intervention. This self-service capability allows the node to autonomously optimize its power consumption and capacity trade-offs based on real-time network state
3Device complexity
If manual configuration of bandwidth is used, then device complexity is reduced, but adaptability to changing network conditions deteriorates
Solution Approach 1:
The patent enables the radio network node to automatically determine and adjust its own bandwidth interval based on monitored UE positions and resource usage. This self-service functionality eliminates the need for manual configuration while providing continuous adaptation to changing network conditions, resolving the contradiction between simplicity and adaptability

AI summary
Embodiments herein may relate to a method performed by a radio network node for handling communication over a bandwidth interval for one or more UEs, in a wireless communication network. The radio network node determines to change a currently used bandwidth interval based on a current state of usage of resources in the currently used bandwidth interval related to number of UEs served and/or a current state of positions of the number of UEs served. With the proviso that it is determined to change the currently used bandwidth interval, the radio network node calculates a changed bandwidth interval to use. The radio network node then adjusts the currently used bandwidth interval to the calculated bandwidth interval; and uses the adjusted bandwidth interval for communicating with the one or more UEs.
