Center Hub Combines Feedback Streams for User Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, user-terminals require additional hardware and software resources to process multiple streams of feedback information from multiple hubs, complicating the receiver design and increasing resource utilization, especially in systems like HRPD networks with asynchronous reverse links.
Innovation Solution
Implementing a system where multiple hubs within the reception range of a user-terminal send their feedback information to a designated center hub, which combines and sends a single feedback stream to the serving hub, allowing the user-terminal to receive only one combined feedback stream, thereby simplifying processing and reducing the need for extra processing elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple hubs send feedback information directly to the user-terminal, then the user-terminal receives comprehensive reception quality information from all hubs, but the user-terminal requires additional processing elements and hardware resources
Solution Approach 1:
The serving hub acts as an intermediary that collects feedback information from multiple hubs and forwards a consolidated stream to the user-terminal. This mediator approach allows the user-terminal to receive comprehensive reception quality information without needing multiple processing elements, as all feedback is delivered through a single channel from the serving hub.
Solution Approach 2:
The feedback information streams from multiple hubs are merged into a single consolidated feedback stream at the serving hub. This combining of multiple information streams into one reduces the complexity at the user-terminal while preserving all necessary reception quality data from the network.
2Adaptability or versatility
If the user-terminal implements multiple processing elements for feedback from multiple hubs, then the user-terminal can process feedback information from all hubs, but the receiver design becomes more complicated
Solution Approach 1:
The serving hub serves as a mediator that handles the complexity of receiving and processing feedback from multiple hubs, thereby shielding the user-terminal from this complexity. The user-terminal maintains a simple, standardized receiver design while still benefiting from comprehensive feedback information delivered through the serving hub.
Solution Approach 2:
The complex functionality of processing multiple feedback streams is extracted from the user-terminal and relocated to the serving hub. This extraction allows the user-terminal to maintain a simple, universal receiver design while the serving hub performs the sophisticated processing of consolidated feedback information.
3Reliability
If extra processing elements are implemented in the user-terminal, then the user-terminal can handle feedback from multiple hubs, but additional hardware and software resources are required
Solution Approach 1:
The serving hub acts as an intermediary that consolidates feedback information from multiple hubs into a single stream, allowing the user-terminal to achieve reliable feedback processing without requiring additional hardware resources. The intermediary handles the multiplicity of feedback streams, enabling the user-terminal to use standard processing elements.
Solution Approach 2:
Multiple feedback information streams are merged into a single consolidated stream at the serving hub, reducing the resource requirements at the user-terminal. This merging allows reliable processing of comprehensive feedback information while minimizing the quantity of hardware and software resources needed at the user-terminal.
