Solution Overview
Problem
Current wireless communications networks face challenges in efficiently managing bandwidth parts (BWPs) for diverse devices with different data traffic profiles, particularly in supporting Ultra Reliable Low Latency Communications (URLLC) services, where existing mechanisms lack control over the activation and deactivation of multiple BWPs simultaneously, leading to suboptimal resource utilization and increased power consumption.
Innovation Solution
A communications device and infrastructure equipment configuration that allows for the dynamic activation and deactivation of multiple bandwidth parts using a processor-controlled transceiver, receiving indications for BWP activation/deactivation, and selecting BWPs based on a maximum permitted number, thereby optimizing resource use and power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple bandwidth parts are activated simultaneously to support diverse data traffic profiles, then the network's ability to handle different services is improved, but the device complexity and power consumption increase
Solution Approach 1:
The system dynamically activates and deactivates bandwidth parts based on real-time traffic requirements. The network can switch between different BWP configurations to adapt to varying service demands, transitioning from static to dynamic resource allocation, thereby managing complexity while maintaining versatility.
Solution Approach 2:
A single communications device is designed to handle multiple bandwidth parts with different configurations, making it universally capable of supporting diverse traffic profiles including eMBB, URLLC, and mMTC services through one multi-functional device rather than requiring separate dedicated devices.
2Adaptability or versatility
If multiple bandwidth parts are activated simultaneously to support diverse data traffic profiles, then the network's ability to handle different services is improved, but the power consumption increases
Solution Approach 1:
The system employs periodic activation and deactivation of bandwidth parts based on traffic patterns. Instead of continuously activating all BWPs, the network periodically switches between active BWPs according to service demands, reducing power consumption while maintaining the ability to support diverse traffic profiles when needed.
Solution Approach 2:
The communications device dynamically adjusts its active BWPs based on real-time traffic requirements, activating only the necessary bandwidth parts when specific services are needed and deactivating them when not required, thereby reducing overall power consumption while maintaining adaptability.
3Device complexity
If a maximum number of activated bandwidth parts is limited to manage device complexity, then the device complexity is reduced, but the productivity and resource utilization efficiency deteriorate
Solution Approach 1:
The system segments the total bandwidth into multiple distinct bandwidth parts, each optimized for specific traffic types. By limiting the number of simultaneously active BWPs to a manageable maximum, the system maintains simple device operation while achieving high resource utilization efficiency through selective activation of the most appropriate BWPs for current traffic demands.
