Multi-Panel UE Evaluation Period for Beam Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in determining an optimal evaluation period for multi-panel user equipment (UE) to assess reference signal quality, which affects beam and cell quality assessment and handover processes.
Innovation Solution
The method involves establishing a time period for evaluating quality parameters of reference signals based on the number of panels or beams monitored by the UE, determining the quality parameter of a beam or cell, and comparing it against a quality threshold, allowing for efficient communication and network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the evaluation period is extended to accurately assess reference signal quality for multi-panel UE, then measurement precision improves, but time consumption increases
Solution Approach 1:
The patent applies dynamics by making the evaluation period configurable and adaptable based on UE capabilities. The network can adjust the evaluation period length according to the number of panels and beams the UE is monitoring, allowing the system to optimize between measurement accuracy and time consumption dynamically rather than using a fixed evaluation period for all UEs
Solution Approach 2:
The patent changes the parameter of evaluation period duration based on UE configuration parameters such as the number of panels and beams. By adjusting this time parameter according to specific UE capabilities and monitoring requirements, the system achieves accurate quality assessment without unnecessarily extending the evaluation period for all cases
2Reliability
If the number of panels and beams monitored by multi-panel UE increases to improve communication reliability, then system reliability improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the monitoring task into manageable units of panels and beams. Each panel can monitor specific beams independently, allowing the UE to handle multiple panels and beams through modular processing rather than treating them as a monolithic complex system
Solution Approach 2:
The patent implements multi-functionality by designing the UE to handle multiple panels and beams through a unified evaluation framework. The same quality assessment mechanisms are applied across different panels and beams, allowing the device to manage increased complexity through standardized processes rather than requiring separate handling for each panel or beam
3Productivity
If the evaluation period is shortened to improve system productivity, then throughput increases, but measurement precision deteriorates
Solution Approach 1:
The patent changes the evaluation period parameter based on the specific requirements of beam and cell quality assessment. By adjusting this parameter according to UE capabilities (number of panels and beams monitored), the system achieves adequate measurement precision without unnecessarily extending the evaluation period, thus maintaining higher system throughput

AI summary
In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications for establishing, by a user equipment (UE), a first time period to evaluate one or more quality parameters of one or more reference signals, wherein the first time period is based on at least one of a number of panels of the UE or a number of beams that the UE monitors simultaneously; determining, by the UE, a quality parameter of a beam or a cell based on the one or more quality parameters of the one or more reference signals; and determining, by the UE, whether the one or more quality parameters of the one or more reference signals exceeds a quality threshold.
