5G UE BWP Camping via Network Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, User Equipment (UE) faces challenges in efficiently camping on bandwidth parts (BWP) or beams due to congestion issues, as existing methods do not effectively manage the selection or reselection of BWP or beam, leading to potential overload on certain BWP or beam.
Innovation Solution
A method and device for UE and network-side configuration that involves receiving or sending selection or reselection configuration information to guide the UE in camping on optimal BWP or beam, balancing load by using criteria such as signal strength and quality, and allowing for intra-frequency or inter-frequency reselection based on specific conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE camps on any BWP or beam without selection configuration, then UE can establish connection quickly, but congestion occurs on certain BWP or beam
Solution Approach 1:
The patent changes the parameter of BWP/beam selection by introducing selection configuration information that provides offset values or priority indicators. This modifies the default camping behavior to distribute UEs across multiple BWPs/ beams based on configured parameters, preventing congestion while maintaining efficient connection establishment.
Solution Approach 2:
The patent introduces selection configuration information as an intermediary element between the network and UE. This configuration information contains offset values or priority indicators that guide UE camping decisions, acting as a mediator to balance load across BWPs/ beams without requiring complex UE-side algorithms.
2Ease of operation
If UE uses simple cell selection criteria, then camping process is fast and simple, but load distribution across BWP or beam is unbalanced
Solution Approach 1:
The patent enhances the simplicity of camping by providing pre-configured selection criteria through selection configuration information. The network configures offset values or priority indicators that UE applies directly, maintaining operational simplicity while achieving balanced load distribution through parameter-based differentiation.
Solution Approach 2:
The patent enables UE to autonomously select optimal BWP/ beam by providing selection configuration information containing offset values or priority indicators. UE independently evaluates BWPs/ beams using these configured parameters and makes camping decisions without complex network coordination, achieving both simplicity and balance.
3Productivity
If network configures multiple BWPs for UE, then system bandwidth utilization improves, but UE complexity in BWP management increases
Solution Approach 1:
The patent manages multiple BWP complexity by introducing selection configuration information with offset values or priority indicators. This parameter-based approach provides clear guidance for BWP selection, allowing UE to efficiently manage multiple BWPs without excessive complexity while maintaining high bandwidth utilization.
