Terminal Station Bandwidth Allocation via Upper-Level Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile radio communication services, conventional terminal station devices struggle to efficiently utilize frequency bands when connected to multiple user devices, as they lack understanding of the connection relationships between devices, leading to suboptimal bandwidth allocation.
Innovation Solution
A terminal station device with an information extraction unit, processing unit, and bandwidth allocation unit that extracts bandwidth allocation information from upper-level devices, creates correspondence information among upper-level, terminal, and lower-level devices, and allocates uplink communication start times and signal amounts based on this information to improve bandwidth utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a terminal station device connects to multiple user devices in one-to-multiple correspondence, then communication capacity and data rate are improved, but the terminal station device cannot efficiently allocate bandwidth because it lacks understanding of connection relationships between devices
Solution Approach 1:
The patent introduces an upper-level device as an intermediary that maintains knowledge of connection relationships between terminal devices and lower-level devices. The terminal station device receives bandwidth allocation information from this intermediary, allowing it to allocate resources efficiently without needing to understand complex connection relationships itself. This resolves the contradiction by enabling multi-device connectivity while maintaining simple bandwidth allocation at the terminal station device.
2Productivity
If the terminal station device calculates transmission start time and signal amount for multiple user devices, then uplink communication efficiency is improved, but the device needs to understand complex connection relationships which increases operational complexity
Solution Approach 1:
The patent extracts the function of maintaining connection relationship knowledge from the terminal station device and places it in the upper-level device. The terminal station device only receives pre-calculated bandwidth allocation information and uses it directly for resource allocation, avoiding the need to understand complex connection relationships. This maintains uplink communication efficiency while preserving operational simplicity.
3Device complexity
If conventional terminal station devices allocate bandwidth without understanding device connections, then device complexity is reduced, but frequency band utilization efficiency deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the upper-level device provides bandwidth allocation information to the terminal station device based on its knowledge of connection relationships. This feedback enables the terminal station device to allocate frequency bands efficiently without increasing its structural complexity, as it simply follows the allocation instructions received from the upper-level device.
Data Source
AI summary
Information on allocation of a bandwidth of uplink communication of each of user devices is extracted from information notified from an upper-level device on the uplink communication of the user devices. Correspondence information is created to indicate a correspondence among the upper-level device, the terminal device, the lower-level device, and the user device. A start time point of the uplink communication of the terminal device and an information amount of signals for which transmission of the uplink communication of the terminal device is allowed are allocated to the terminal device on the basis of the information on allocation of the bandwidth of the uplink communication of each of the user devices and the correspondence information.
