Service-Specific Beam Optimization for 5G Network Slices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cellular network base stations often use a single beam for all user equipment, leading to poor service experiences for users requesting different services like IoT, eMBB, and URLLC, as existing systems fail to adapt beam configurations to specific service types.
Innovation Solution
Implementing a method and system for service-specific beam optimization, where a base station receives protocol data unit (PDU) session requests and assigns dedicated beams to user equipment based on the requested service slice, allowing for dynamic reconfiguration based on usage data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single beam is used for all user equipment, then device complexity is reduced, but service quality for different service types deteriorates
Solution Approach 1:
The patent divides the single beam into multiple service-specific beams (e.g., eMBB beam, URLLC beam, IoT beam). Each beam is dedicated to a specific service type with optimized parameters, allowing the system to maintain manageable complexity while significantly improving service quality for different service types through segmentation of the beamforming resources.
2Reliability
If dedicated beams are assigned to different service types, then service quality is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic beam selection and switching mechanisms where the base station can dynamically assign appropriate beams to UEs based on their service type requirements. The system dynamically adjusts beam configurations, switching between different service-specific beams as needed, which manages complexity through dynamic resource allocation rather than static dedicated beams for each service type.
3Reliability
If beam configuration is optimized for each service type, then service-specific performance is improved, but system adaptability deteriorates
Solution Approach 1:
The patent creates a universal beam management system where the base station can handle multiple service types through a unified framework. The system uses universal signaling mechanisms and standardized beam configuration protocols that work across different service types, allowing the network to maintain high service-specific performance while preserving system adaptability through universal handling procedures.

AI summary
Aspects provided herein provide methods, systems, and a non-transitory computer storage media storing instructions for service specific beam optimization. The method begins with receiving a first protocol data unit (PDU) session request from a first user equipment (UE) comprising a request for a first slice. The method also includes determining a first service to allocate to the first UE based on the first slice requested. A first beam is then assigned to the first UE, with the first beam assigned based on the first slice requested. The beams assigned to different types of service may be dynamically changed when usage patterns change as indicated by network data collected.
