Default Bandwidth Part Switching for Low-Latency Wireless Tasks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing bandwidth parts (BWP) transitions, particularly in switching from an active BWP to a default BWP, which can impact communication efficiency and resource utilization.
Innovation Solution
User equipment (UE) and network nodes are equipped with mechanisms to receive and transmit default BWP configurations, enabling seamless switching from an active BWP to a default BWP, thereby optimizing wireless communication tasks based on these configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the system switches from an active bandwidth part to a default bandwidth part, then communication efficiency is improved and resource allocation is optimized, but switching latency and transition time increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring default bandwidth part information in advance before switching is needed. The network node provides default BWP configuration to the UE beforehand, so when switching from active BWP to default BWP is required, the UE can immediately use the pre-configured parameters without waiting for new configuration messages, thereby reducing switching latency while maintaining optimized resource allocation
2Adaptability or versatility
If default bandwidth part configuration is transmitted to user equipment, then adaptability and resource management flexibility are improved, but signaling overhead and system complexity increase
Solution Approach 1:
The patent applies universality by designing the default bandwidth part configuration to serve multiple functions simultaneously. The same default BWP configuration is used for various purposes including initial access, random access procedures, and fallback scenarios when active BWP needs to be released. This multi-functional approach enhances resource management flexibility without proportionally increasing signaling overhead, as a single configuration structure serves multiple adaptability requirements
