Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current BWP switching techniques in mobile communications are slow, leading to inefficiencies in system performance due to the time required for software and radio frequency reconfigurations during the BWP switching process.
Innovation Solution
Proposed methods include restricted software and radio frequency reconfigurations, redefining the BWP transition timeline, and pattern-based switching to expedite the BWP switching process, allowing for faster transitions and improved system performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If full software and radio frequency reconfigurations are performed during BWP switching, then comprehensive bandwidth adaptation is achieved, but switching delay increases
Solution Approach 1:
The patent segments the BWP switching process into two distinct phases: a fast switching phase that handles urgent bandwidth changes with minimal delay, and a complete reconfiguration phase that performs full software and RF reconfiguration. This segmentation allows the system to provide quick responses when needed while maintaining the option for thorough reconfiguration when time is not critical, thus resolving the contradiction between switching speed and adaptation completeness.
Solution Approach 2:
The patent applies partial reconfiguration by performing only essential software and RF settings during fast BWP switching, rather than complete reconfiguration. This partial action achieves sufficient bandwidth adaptation for time-critical scenarios while avoiding the full time cost of complete reconfiguration, effectively balancing adaptability requirements with switching delay constraints.
2Speed
If BWP switching delay is reduced through restrictions on reconfiguration, then switching speed improves, but reconfiguration completeness decreases
Solution Approach 1:
The patent introduces dynamic reconfiguration modes that can be selected based on system conditions and requirements. The network can dynamically choose between fast switching mode (with restrictions) and complete reconfiguration mode (without restrictions), allowing the system to adapt its complexity level to the specific situation, thus resolving the contradiction between switching speed and reconfiguration completeness.
Solution Approach 2:
The patent changes the reconfiguration parameter set during fast BWP switching by selectively applying only a subset of software and RF reconfiguration parameters rather than all parameters. This parameter selection approach enables faster switching by reducing the number of reconfiguration operations while still achieving the essential bandwidth change, thereby resolving the contradiction between speed and complexity.
3Manufacturing precision
If complete BWP reconfiguration is performed, then bandwidth adaptation accuracy is improved, but system productivity during switching decreases
Solution Approach 1:
The patent implements periodic complete reconfiguration at scheduled intervals or under specific conditions, rather than requiring complete reconfiguration for every BWP switch. Between these periodic complete reconfigurations, fast restricted reconfigurations are performed, maintaining acceptable bandwidth adaptation accuracy while preserving system productivity during intermediate switching operations.
Data Source
AI summary
Various examples pertaining to enhancements for faster bandwidth part (BWP) switching in mobile communications are described. An apparatus, implementable in a user equipment (UE), receives a trigger from a network node. In response to receiving the trigger, the UE performs BWP switching with a restriction on software (SW) or radio frequency (RF) reconfiguration such that the BWP switching is faster with the restriction than without the restriction. The UE then performs a transmission to the network node after the BWP switching.
