Base Station Code Processing Assistance via Intermediary Transceiver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In code division multiplexing wireless communication systems, base station transceivers may experience performance issues due to high radio noise levels and poor signal-to-noise ratios, leading to inefficient communication services for users.
Innovation Solution
A network control system monitors performance measurements from base station transceivers and directs nearby transceivers with better conditions to provide code processing assistance by reallocating processing resources to decode signals using the affected transceiver's codes, ensuring continuous communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a base station transceiver operates independently with its own code, then it maintains operational autonomy and simplicity, but it experiences performance degradation due to high radio noise levels and poor signal-to-noise ratios
Solution Approach 1:
The patent introduces an assisting base station transceiver as an intermediary to help the affected base station process communications. The assisting transceiver receives and processes signals using the affected transceiver's code, then forwards the processed communications to the affected transceiver, thereby improving reliability without requiring the affected transceiver to directly overcome its poor signal conditions
Solution Approach 2:
The patent merges the processing capabilities of a second base station transceiver with the code processing needs of the first base station transceiver. By combining resources and processing power of multiple transceivers while maintaining code-specific separation, the system achieves better performance without proportionally increasing overall system complexity
2Reliability
If base station transceivers are assigned unique codes for code division multiplexing, then communication separation and user identification are achieved, but performance issues arise when radio noise levels are high and signal-to-noise ratios are poor
Solution Approach 1:
The assisting base station transceiver acts as a mediator that receives the noisy signals intended for the affected transceiver, processes them using the appropriate code in its own better signal environment, and forwards the cleaned communications. This intermediary approach effectively filters out radio noise that would otherwise degrade signal reception quality
Solution Approach 2:
The system creates a virtual copy of the code processing function by having the assisting transceiver perform code processing operations that mirror what the affected transceiver would need to do, but in a environment with better signal-to-noise ratio. This copying of processing capability at a different location mitigates the harmful effects of radio noise

AI summary
A first base station transceiver wirelessly receives communications from a first user in a code division multiplexing format using a first code assigned to the first base station transceiver. A second base station transceiver wirelessly receives communications from a second user in the code division multiplexing format using a second code assigned to the second base station transceiver. The base station transceivers determine and transfer wireless communication performance measurements. A network control system selects the second base station transceiver to assist the first base station transceiver based on the communication performance measurements. In response, the second base station transceiver wirelessly receives communications from a third user in the code division multiplexing format using the first code assigned to the first base station transceiver.
