Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication devices face interference issues when operating multiple radio access technologies, such as LTE, Bluetooth, and WLAN, due to overlapping frequency bands, leading to coexistence problems that affect performance and connectivity.
Innovation Solution
A radio communication device with multiple transceivers and processors is designed to manage real-time and non-real-time transceiver control information, using protocol synchronization and traffic arbitration to coordinate the operation of LTE, Bluetooth, and WLAN technologies, thereby minimizing interference and enhancing coexistence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio access technologies operate in parallel using overlapping frequency bands, then communication versatility and functionality are improved, but interference between technologies increases and coexistence performance deteriorates
Solution Approach 1:
The patent segments the control of different radio access technologies by introducing separate processors for each technology (first processor for LTE, second processor for Bluetooth/WLAN) and dedicated transceivers. This segmentation allows independent control and management of each technology, reducing mutual interference while maintaining the ability to operate multiple technologies in parallel.
Solution Approach 2:
The patent introduces a third processor as an intermediary that coordinates between the first and second processors. This intermediary processor determines real-time and non-real-time transceiver control information, managing resource allocation and timing coordination to minimize interference between different radio access technologies while preserving communication versatility.
2Reliability
If real-time control coordination is implemented between transceivers, then interference reduction and coexistence performance are improved, but system complexity and processing requirements increase
Solution Approach 1:
The control functions are segmented into different processors: the first processor handles LTE control, the second processor handles Bluetooth/WLAN control, and the third processor handles coordination. This segmentation distributes the complexity across multiple dedicated components rather than concentrating all control logic in a single complex unit.
Solution Approach 2:
The third processor determines transceiver control information in advance, including real-time control for immediate coordination and non-real-time control for future resource allocation. This preliminary action allows the system to proactively manage potential interference scenarios before they occur, improving coexistence performance while organizing complexity in a structured manner.
