Wireless Relay Hop Count Selection for LTE Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, particularly LTE networks, there is a need for efficient user equipment (UE) selection mechanisms that consider hop count data to optimize data communication paths and service quality, as existing systems lack a standardized method for UE to select wireless relays based on hop count and service-specific criteria.
Innovation Solution
The implementation of a data communication network that allows wireless relays to broadcast System Information Blocks (SIBs) including their individual hop counts, enabling User Equipment (UEs) to select relays based on hop count thresholds and service capabilities, with relays incrementing and broadcasting hop counts in a daisy chain configuration to facilitate efficient data routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wireless relays are used to extend coverage area, then network coverage is improved, but network complexity increases due to daisy chain configurations
Solution Approach 1:
The patent introduces hop count information as an intermediary parameter that mediates between the extended network coverage and the complexity of daisy chain configurations. This parameter enables UEs to make informed selection decisions without requiring complex network management, thus resolving the contradiction between coverage extension and system complexity.
2Ease of operation
If UEs select relays without hop count information, then selection process is simple, but data communication efficiency deteriorates
Solution Approach 1:
The patent implements preliminary action by having wireless relays broadcast hop count information in advance through System Information Blocks before UE selection occurs. This allows UEs to efficiently select relays based on pre-available hop count data, improving data communication efficiency without complicating the selection process.
3Measurement precision
If hop count information is broadcasted to all UEs, then UE selection accuracy is improved, but network signaling overhead increases
Solution Approach 1:
The patent applies universality by utilizing existing System Information Blocks, which are already broadcast for other network information purposes, to carry hop count information. This multi-functional use of existing signaling structures improves UE selection accuracy without significantly increasing network signaling overhead.

AI summary
A wireless relay attaches to a wireless base station and broadcasts a wireless hop count. Another wireless relay receives the wireless hop count and attaches to the wireless relay. The other wireless relay increments the wireless hop count and broadcasts the incremented wireless hop count. The wireless relays receive attachment requests from User Equipment (UEs) responsive to their wireless hop counts. The wireless relays exchange user data with the UEs after the attachments.
