Wireless Device Coexistence Interference Management via AP Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face interference issues due to the coexistence of multiple radio access technologies (RATs), which can lead to performance degradation and inefficiencies in communication.
Innovation Solution
A wireless device determines the communication patterns of a second device using a different RAT, such as periodic or repetitive communication, and transmits this information to an access point (AP), allowing the AP to avoid scheduling conflicts and reduce interference by determining unavailable times for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio access technologies operate simultaneously in a wireless device, then the device can support diverse communication protocols and maintain connectivity across different networks, but interference between RATs occurs leading to performance degradation
Solution Approach 1:
The patent segments communication resources by creating separate communication pools for different RATs (first communication pool for first RAT, second communication pool for second RAT). Each pool operates independently with its own scheduling, preventing interference between RATs while maintaining multi-RAT support. The wireless device divides available communication resources into distinct time-frequency-space segments allocated to different RATs.
Solution Approach 2:
The patent implements dynamic scheduling where the AP adjusts communication opportunities for different RATs based on current network conditions, traffic requirements, and interference levels. The scheduling is not static but adapts in real-time, allowing the system to optimize performance by dynamically allocating resources between competing RATs while maintaining reliability.
2Productivity
If communication resources are shared among multiple RATs, then resource utilization efficiency improves, but scheduling conflicts and interference increase
Solution Approach 1:
The patent introduces an intermediary scheduling mechanism at the AP that mediates between different RATs. The AP acts as a mediator that receives communication requirements from multiple RATs, coordinates their resource needs, and allocates resources in a way that prevents conflicts. This intermediary layer resolves scheduling conflicts before they manifest as interference, allowing efficient resource sharing without harmful interactions.
Solution Approach 2:
The patent applies local quality by allowing different communication pools to have different resource allocation strategies, scheduling parameters, and interference management techniques tailored to each RAT's specific requirements. Each RAT receives customized resource allocation rather than a one-size-fits-all approach, optimizing performance for each technology while sharing overall system resources efficiently.

AI summary
Methods, systems and apparatuses for managing coexistence interference by an access point (AP) and wireless device are described. The wireless device may perform communication with the AP and with another device. The wireless device may indicate characteristics of its communication patterns with the other device to the AP. The AP may determine times to communicate and/or avoid communication with the wireless device based on the characteristics.
