Beam Switching Priorities Under UE Capability Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently managing beam switching due to limitations in UE capabilities, leading to inaccurate location determination 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 for beam switching based on priorities, prioritizing high-priority operations like PRS measurements and data transmission, while optimizing beam usage within its capability constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam switching opportunities are allocated to PRS measurements, then location determination accuracy is improved, but high-priority data transmission is delayed
Solution Approach 1:
The patent implements dynamic beam switching by allowing the UE to adaptively select between different transmission types (PRS or data) based on real-time conditions and priorities. The beam switching behavior is no longer static but dynamically adjusted according to the priority indicators received from the network and current operational requirements, resolving the contradiction between location accuracy and data transmission timeliness.
Solution Approach 2:
The patent changes the parameter of beam switching priority by introducing priority indicators that can be configured by the network. This allows the system to flexibly adjust which transmission type receives beam switching resources at different times, transforming the fixed resource allocation into a variable parameter system that can optimize for location accuracy or data transmission depending on current needs.
2Measurement precision
If UE prioritizes PRS measurements over data transmission, then location determination is accurate, but resource utilization efficiency decreases
Solution Approach 1:
The patent introduces configurable priority indicators that allow the network to dynamically adjust the relative priority of PRS measurements versus data transmission. This parameter change enables the system to optimize resource utilization by assigning appropriate priorities based on current network conditions, UE capabilities, and service requirements, rather than using a fixed priority scheme.
Solution Approach 2:
The patent implements a feedback mechanism where the network receives information about UE beam switching capabilities and priorities, then configures appropriate priority indicators in response. This closed-loop feedback system allows the network to optimize resource allocation based on actual UE performance and network conditions, improving overall resource utilization efficiency while maintaining location determination accuracy when needed.
3Device complexity
If UE beam switching capability is limited, then device complexity is reduced, but transmission reliability for high-priority operations deteriorates
Solution Approach 1:
The patent addresses the reliability issue by introducing priority indicators that allow the network to configure beam switching behavior according to UE capabilities. For UEs with limited beam switching capability, the network can prioritize certain transmission types (such as high-priority data or PRS measurements) to ensure reliable transmission, effectively compensating for the hardware limitations through intelligent resource allocation.
