Base Station Height-Based Indication for Aerial User Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication networks face challenges in supporting aerial user terminals due to their high mobility, variable height, and complex propagation conditions, which can lead to interference and suboptimal communication performance compared to terrestrial user terminals.
Innovation Solution
A base station generates and transmits indication information about its support capabilities for user terminals of different heights and types, allowing user terminals to select appropriate cells for communication, thereby optimizing access and measurement processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station serves aerial user terminals without height-based differentiation, then the network structure remains simple, but communication performance deteriorates due to variable propagation conditions and interference
Solution Approach 1:
The patent segments user terminals into different height categories (first height range and second height range) and applies different access control policies to each segment. The base station generates indication information that distinguishes between terrestrial and aerial user terminals, allowing tailored resource allocation and interference management for each segment, thereby improving communication performance while maintaining manageable network complexity through structured differentiation.
2Ease of operation
If the base station provides unified access control for all user terminals, then the system is easy to operate, but aerial user terminals experience suboptimal performance due to their high mobility and different propagation conditions
Solution Approach 1:
The patent implements local quality by applying different access control parameters and policies to different user terminal categories. The base station generates indication information that provides height-specific or type-specific access control settings, allowing optimal resource allocation for aerial terminals with high mobility while maintaining simple unified operation procedures. This localized differentiation improves communication performance without complicating the overall system operation.
3Reliability
If the base station does not provide height-specific indication information, then the information transmission is minimal, but user terminals cannot select appropriate cells leading to increased interference and poor performance
Solution Approach 1:
The base station performs preliminary action by generating and transmitting indication information in advance before the user terminal needs to select a cell. This indication information includes height-specific or type-specific capability details that enable user terminals to make informed cell selection decisions. By providing this information proactively, the system avoids subsequent interference issues and performance degradation while maintaining efficient information transmission through targeted, pre-planned communication.
