Collocated WLAN WAN Entity Assisted SON Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face inefficiencies in self-organizing network configurations, particularly in dense environments where interference from multiple small cells leads to poor resource utilization and degraded communication quality, making it difficult for user equipment (UE) to obtain reliable measurement information for interference management.
Innovation Solution
A WLAN-assisted WAN SON solution is implemented, where a collocated WLAN entity receives measurement information from the UE and embeds WAN entity-specific information into beacon signals, enabling effective interference management and configuration of WAN entities in small cells, even in high-interference environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple small cells are deployed to improve wireless network coverage, then network coverage and capacity are improved, but interference between cells increases and resource utilization deteriorates
Solution Approach 1:
The patent introduces a SON entity as an intermediary that mediates between multiple small cells. This entity collects measurement information from UEs, processes interference data, and generates configuration parameters to coordinate resource allocation across cells, thereby reducing inter-cell interference while maintaining network coverage expansion
Solution Approach 2:
The patent implements a feedback mechanism where UEs continuously provide measurement information (such as interference levels and signal quality) to the SON entity. The SON entity uses this feedback to dynamically adjust configuration parameters like reference signal power and resource allocation, creating a closed-loop system that adapts to changing interference conditions
2Device complexity
If traditional SON configuration methods are used in dense small cell environments, then device complexity is reduced, but measurement precision and interference management capability deteriorate
Solution Approach 1:
The patent segments the complex interference management task into distinct functional components: measurement collection by UEs, data aggregation by the SON entity, interference analysis, and configuration parameter generation. This segmentation allows each component to focus on a specific function, improving measurement precision without requiring any single device to handle all complexity
3Reliability
If collocated WLAN and WAN entities are used for assisted SON, then interference management capability is improved, but device complexity increases
Solution Approach 1:
The patent merges WLAN and WAN entities into a collocated infrastructure where both radio access technologies share common hardware resources and are coordinated by a single SON entity. This consolidation improves interference management by enabling joint optimization of both networks while the shared infrastructure reduces overall system complexity compared to separate independent systems

AI summary
The present methods and apparatus relate to managing interference associated with a configuration of a self-organizing network (SON) during wireless communication, comprising receiving, at a first radio access technology (RAT) entity, measurement information from a user equipment (UE) for assisting with interference management at a second RAT entity, wherein the first RAT entity is collocated with the second RAT entity; and configuring the second RAT entity based at least in part on the measurement information received by the first RAT entity. In a further aspect, the present methods and apparatus comprise embedding, by a first RAT entity, RAT entity-specific information of a second RAT entity in a management indication, wherein the first RAT entity and the second RAT entity are collocated; and transmitting the management indication to one or both of a UE and another first RAT entity.
