Base Radio Status Information Merging for Bandwidth Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the bandwidth is inefficiently utilized due to periodic and unconfirmed data transmissions, particularly in applications like GPS-based systems where location updates dominate, leading to idle outbound frequencies from infrastructure equipment to terminals.
Innovation Solution
A method where a base radio combines status information from multiple inbound frequencies and transmits it on a single outbound frequency, allowing radio terminals to select an available inbound frequency for data transmission, thereby reducing the number of frequencies needed and improving bandwidth utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each base radio uses separate outbound frequencies for status information transmission, then status information can be transmitted reliably, but the number of frequencies required increases and bandwidth utilization decreases
Solution Approach 1:
Multiple outbound frequencies carrying status information from different base radios are merged into a single frequency. The base radio receives status information from multiple inbound frequencies, combines them, and transmits the combined status information on one outbound frequency, reducing the total number of frequencies required in the system.
Solution Approach 2:
A single outbound frequency serves multiple base radios by carrying combined status information from all of them. This multi-functional use of the frequency resource allows the same frequency to fulfill the status transmission role for multiple base radios simultaneously, improving spectral efficiency.
2Reliability
If dedicated transmission channels are allocated for location updates, then location update reliability is improved, but bandwidth utilization deteriorates due to idle outbound frequencies
Solution Approach 1:
The patent combines status information from multiple base radios onto a single outbound frequency, freeing up other outbound frequencies that were previously dedicated for status transmission. These freed frequencies can then be utilized for data transmissions including location updates, thereby improving overall bandwidth utilization while maintaining reliable communication channels.
Solution Approach 2:
The system dynamically allocates frequencies based on actual needs. Instead of statically dedicating outbound frequencies for status information, the system uses a single frequency for combined status transmission and allows other frequencies to be dynamically used for data communications, adapting to varying traffic conditions and improving bandwidth efficiency.
3Productivity
If multiple frequencies are used for inbound communication from multiple base radios, then communication capacity increases, but the complexity of frequency management and monitoring increases
Solution Approach 1:
The patent merges multiple outbound frequency monitoring requirements into a single frequency. Radio terminals only need to monitor one outbound frequency to receive combined status information from all base radios, significantly reducing the complexity of frequency monitoring and management while maintaining the ability to handle communications from multiple base radios.
Data Source
AI summary
A method for facilitating transmission of data in a communication system is provided herein. In operation, a base radio of a plurality of base radios combines status information corresponding to a plurality of inbound frequencies and transmits the combined status information on a single outbound radio frequency. Further, each of the plurality of inbound radio frequencies corresponds to one of the plurality of base radios. Then, one or more radio terminals monitor the single outbound radio frequency to receive the combined status information, determine at least one available inbound radio frequency from the plurality of inbound radio frequencies based on the received combined status information, selects an inbound radio frequency of the at least one available inbound frequency, and transmitting the data using the selected inbound radio frequency to the corresponding base radio.
