Multi-Hop Terminal Base Station Connection via Tolerable Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless multi-hop networks, the existing method of terminal selection based on reference signal received power (RSRP) increases interference and degrades system performance, making it difficult to provide stable communication services.
Innovation Solution
A method that involves receiving cell selection and reselection criteria from a base station, determining candidate base stations based on RSRP and quality thresholds, and selecting a target base station using a lightening backhaul load (LBL) or maximum RSRP scheme to minimize interference and optimize communication performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminal selects base station based on RSRP, then connection simplicity is improved, but interference increases and system performance degrades
Solution Approach 1:
The patent introduces a new parameter 'tolerable gap' that modifies the traditional RSRP-based selection criterion. Instead of simply selecting the base station with maximum RSRP, the terminal now uses a composite criterion that incorporates the tolerable gap parameter to adjust selection behavior, thereby reducing interference while maintaining operational simplicity.
Solution Approach 2:
The patent enables dynamic selection between two connection schemes (maximum RSRP scheme and LBL scheme) based on network conditions. The terminal can adaptively switch between these schemes, making the connection process dynamic rather than static, which allows optimization of both simplicity and performance according to current network state.
2Ease of operation
If terminal selects base station based on RSRP, then connection process is simplified, but stability of communication service deteriorates
Solution Approach 1:
The patent modifies the connection selection parameters by introducing 'tolerable gap' and enabling dynamic switching between maximum RSRP scheme and LBL scheme. This parameter enhancement allows the system to maintain simple connection procedures while achieving more stable communication services through intelligent parameter adjustment.
3Ease of operation
If terminal selects base station based on RSRP, then ease of connection is improved, but interference in wireless backhaul network increases
Solution Approach 1:
The patent introduces the 'tolerable gap' parameter that fundamentally changes the connection selection criterion from pure RSRP maximization to a more nuanced approach. This parameter change enables the terminal to select base stations in a way that reduces wireless backhaul interference while preserving the ease of connection.
Solution Approach 2:
The patent implements a feedback mechanism where the terminal evaluates both RSRP and tolerable gap values, and can dynamically switch between connection schemes based on network conditions. This feedback-driven approach allows the system to reduce interference by adjusting selection behavior according to current network state.

AI summary
Disclosed are a method and apparatus for connecting a terminal and a base station in a multi-hop network. A method of a terminal may comprise: receiving cell selection and reselection criteria information broadcast from a base station; determining candidate base stations among all base stations capable of communicating with the terminal based on the cell selection and reselection criteria information; selecting one connection scheme from a lightening backhaul load (LBL) scheme or a maximum reference signal received power (RSRP) scheme based on a tolerable gap, which is a parameter for determining the candidate base station; selecting one candidate base station from among the candidate base stations as a target base station based on the one connection scheme; and connecting to the target base station.
