Booster Cell Activation Control for 5G Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems, such as 5G networks, lack the ability to dynamically activate or deactivate booster cells based on user equipment mobility, service requirements, and load conditions, leading to inefficient energy usage and suboptimal Quality of Service.
Innovation Solution
An apparatus and method for an access point to manage booster cells by determining the need for activation or deactivation of coverage areas using a cell booster table, considering user equipment capabilities, mobility, and Key Performance Indicators, and transmitting requests to booster cells to adjust beam or cell levels of coverage dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If booster cells are continuously active to ensure coverage, then Quality of Service is maintained, but energy consumption increases
Solution Approach 1:
The patent implements dynamic activation and deactivation of booster cells based on real-time network conditions, user equipment mobility, and service requirements. The system transitions from static continuous operation to dynamic state changes, activating booster cells only when needed and deactivating them when not required, thereby resolving the contradiction between maintaining QoS and reducing energy consumption
Solution Approach 2:
The system changes operational parameters of booster cells by adjusting their activation state based on multiple factors including UE mobility patterns, service type requirements, and current load conditions. This parameter adjustment allows the system to optimize the balance between QoS maintenance and energy efficiency
2Use of energy by moving object
If booster cells are deactivated to save energy, then energy efficiency improves, but Quality of Service deteriorates
Solution Approach 1:
The patent employs feedback mechanisms that continuously monitor network conditions, UE mobility, and service requirements to determine when booster cells should be activated or deactivated. This feedback loop ensures that QoS is maintained by activating booster cells when conditions indicate a need, while allowing energy savings when conditions permit deactivation
Solution Approach 2:
The system performs preliminary assessments of network conditions, UE mobility patterns, and service requirements before making activation decisions. By evaluating these factors in advance, the system can proactively activate or deactivate booster cells to prevent QoS degradation while maximizing energy efficiency
3Use of energy by moving object
If beam-level control is implemented for booster cells, then energy efficiency improves through selective activation, but device complexity increases
Solution Approach 1:
The patent segments the booster cell coverage area into multiple beams, allowing selective activation and deactivation of individual beams based on specific directional requirements. This segmentation enables fine-grained control where only necessary beams are activated, improving energy efficiency while the modular nature of beam management helps manage the associated complexity
4Reliability
If booster cells are activated based on multiple parameters, then Quality of Service is optimized, but device complexity increases
Solution Approach 1:
The patent implements a multi-functional decision-making mechanism that evaluates multiple parameters including UE mobility, service requirements, and network conditions using a unified framework. This universal approach consolidates various control functions into a single coordinated system, optimizing QoS through comprehensive parameter consideration while managing complexity through integrated rather than separate control mechanisms

AI summary
An apparatus for an access point configured to provide a first coverage area, the apparatus comprising: means for determining to deactivate or activate at least part of a second coverage area located within the first coverage area, the second coverage area being provided by a booster cell; means for identifying said booster cell: and means for transmitting a request to said booster cell to deactivate and/or activate the at least part of the second coverage area in dependence on said determination, wherein said request identifies whether the activation and/or deactivation is to be provided at a beam-level or at a cell-level of the second coverage area.
