Solution Overview
Problem
Current Bluetooth Low Energy (BLE) technologies face challenges in coexisting with other short-range wireless communication technologies, leading to interference, increased retransmissions, latency, and reduced throughput due to overlapping transmission patterns in shared frequency ranges.
Innovation Solution
A method and apparatus for configuring a short-range wireless communication link that maximizes retransmission opportunities and selects coexistence transmission patterns to minimize interference between BLE and other technologies like WLAN, by dynamically allocating subevents and adjusting based on link quality and demand, thereby optimizing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication technologies share the same frequency range, then wireless communication coverage is expanded, but interference between technologies increases
Solution Approach 1:
The patent segments the shared frequency spectrum into distinct time slots or subevents, allocating specific time intervals to different communication technologies (BLE and WLAN). This temporal segmentation prevents simultaneous transmissions on the same frequency, thereby eliminating interference while maintaining full frequency utilization across both technologies.
2Reliability
If retransmission opportunities are increased to improve reliability, then transmission reliability improves, but latency increases
Solution Approach 1:
The patent implements dynamic adjustment of retransmission opportunities based on real-time link quality assessment. When link quality is good, fewer retransmission opportunities are allocated, reducing latency. When link quality deteriorates, more retransmission opportunities are provided to maintain reliability. This dynamic allocation optimizes the trade-off between reliability and latency.
3Reliability
If coexistence transmission patterns are configured to reduce interference, then transmission reliability improves, but device complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the communication device automatically assesses link quality, selects appropriate coexistence transmission patterns, and configures retransmission opportunities without external intervention. The device monitors transmission outcomes and autonomously adjusts parameters to maintain optimal performance, reducing the perceived complexity for users while ensuring reliable coexistence.
