Beam Switching Priority Selection Under UE Capability Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing beam switching due to limited UE capabilities, leading to inaccurate location estimation and delayed high-priority data transmission, as beam switching opportunities are consumed by lower-priority operations like PRS measurements.
Innovation Solution
User equipment (UE) selects transmission types based on priorities, prioritizing high-priority operations like PRS measurements and data transmission, while optimizing beam switching within its capability constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam switching opportunities are used for PRS measurements, then location estimation accuracy is improved, but high-priority data transmission is delayed
Solution Approach 1:
The system performs preliminary actions by pre-configuring beam switching opportunities and priorities before actual communication occurs. The UE is configured with a set of beams and priority rules in advance, allowing it to autonomously select which beams to use for PRS measurements versus data transmission based on pre-established criteria, thus preventing delays without sacrificing location accuracy.
Solution Approach 2:
The system dynamically adjusts beam switching behavior based on real-time conditions. The UE can flexibly select which beams to switch to for PRS measurements versus data transmission, adapting its behavior dynamically based on current network conditions, signal quality, and priority requirements, thereby optimizing both location estimation and data transmission timing.
2Adaptability or versatility
If UE performs beam switching for multiple transmission types, then communication flexibility is improved, but UE capability constraints are exceeded
Solution Approach 1:
The system segments beam switching operations into distinct categories or types, each with its own priority level and resource allocation rules. By dividing the complex task of beam switching into manageable segments (e.g., PRS measurement beams vs. data transmission beams), the UE can manage its limited capabilities more effectively while maintaining overall communication flexibility.
Solution Approach 2:
Different beams or beam groups are assigned different qualities or priorities based on their specific functions. Some beams are designated as high-priority for PRS measurements while others are designated for data transmission, allowing the UE to allocate its limited switching capabilities locally to the most critical functions first, thereby maintaining flexibility without exceeding device constraints.
3Productivity
If lower-priority operations consume beam switching resources, then resource utilization is improved, but high-priority data transmission is blocked
Solution Approach 1:
The system implements feedback mechanisms where the network continuously monitors beam switching usage and adjusts configurations accordingly. The network receives feedback about which beams are being used for PRS measurements versus data transmission and can dynamically reconfigure priority levels or allocate resources to ensure high-priority data transmission is not blocked, while still allowing lower-priority operations to utilize available resources efficiently.
