Bandwidth Part Coordination for Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G and 6G technologies, face challenges in dynamically managing bandwidth parts (BWPs) across different radio access technologies, leading to inefficiencies in data transfer due to lack of coordination between cellular modems and Wi-Fi access points, resulting in suboptimal power management and user experience.
Innovation Solution
The implementation of a communications manager that enables exchange of information between Wi-Fi schedulers and 5G connection managers to dynamically adjust bandwidth, allowing for real-time BWP configuration and switching based on traffic flow conditions, congestion indications, and inactivity timers, ensuring optimal bandwidth allocation and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If bandwidth parts are managed independently in cellular and Wi-Fi networks, then each network can operate autonomously, but coordination between networks is lacking leading to suboptimal power management and data transfer efficiency
Solution Approach 1:
The patent combines bandwidth part management functionality across cellular modem and Wi-Fi access point into a unified system. The communications manager integrates BWP configuration from cellular network with Wi-Fi bandwidth allocation, enabling coordinated bandwidth management that adapts to overall traffic conditions while maintaining autonomous operation capabilities of each network type.
2Productivity
If bandwidth is dynamically adjusted based on traffic flow conditions, then data transfer efficiency improves, but latency in detecting and responding to congestion increases
Solution Approach 1:
The patent implements feedback mechanisms where the communications manager continuously monitors traffic flow conditions, congestion indicators, and bandwidth utilization across both cellular and Wi-Fi networks. This real-time feedback enables dynamic adjustment of bandwidth parts based on actual network conditions, improving data transfer efficiency while minimizing response latency through continuous monitoring and adaptive control.
3Productivity
If multiple bandwidth parts are configured for different traffic flows, then bandwidth allocation optimality improves, but the complexity of managing and switching between BWPs increases
Solution Approach 1:
The patent segments bandwidth management into distinct bandwidth parts, each configured for specific traffic flows or network conditions. The communications manager divides the total available bandwidth into multiple BWPs that can be independently allocated and managed, allowing optimal bandwidth allocation for different traffic types while simplifying management through modular, segmented control rather than monolithic bandwidth management.

AI summary
Methods, systems, and devices for wireless communication are described. A communication device, such as a customer premises equipment (CPE) may include or otherwise be in communication with a cellular modem and a wireless local area network (WLAN) access point (AP). The CPE may receive a first indication of a bandwidth part (BWP) configuration identifying an active BWP for the wireless communication. The CPE may send a second indication to switch to the active BWP for the wireless communication based on the BWP configuration. The CPE may communicate with stations (STAs) served by the CPE based on the active BWP. Additionally or alternatively, when the CPE detects a need for additional bandwidth, the CPE can request for additional bandwidth parts (e.g., BWPs).
