UE Antenna Panel Prioritization for Scheduling Reception Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 5G standard does not require user equipment (UE) devices to prioritize the reception of critical data transmissions, leading to potential failures in receiving uplink and downlink scheduling information, which can violate Quality of Service (QoS) and Quality of Experience (QoE) requirements due to conflicting measurement periods and suboptimal antenna panel usage.
Innovation Solution
UE devices and radio access network (RAN) nodes implement configuration mechanisms to designate priority time windows for scheduling information reception and signal quality measurements, allowing the UE to prioritize using the best antenna panel during these windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE devices perform signal quality measurements during dedicated measurement periods, then measurement accuracy is improved, but reception of critical scheduling information may be lost
Solution Approach 1:
The patent applies dynamics by making the antenna panel configuration dynamic and adjustable. The UE can switch between different antenna panels based on real-time requirements - using a first antenna panel for signal quality measurements and a second antenna panel for receiving scheduling information when conflicts occur. This dynamic reconfiguration resolves the contradiction by allowing the system to adapt its antenna usage pattern rather than being fixed, thus maintaining both measurement accuracy and reception reliability.
Solution Approach 2:
The patent segments the antenna panel functionality by designating different antenna panels for different purposes. Specifically, it divides the antenna resources into a first antenna panel dedicated for signal quality measurements and a second antenna panel dedicated for receiving scheduling information. This segmentation allows simultaneous or near-simultaneous operation of both functions without interference, resolving the contradiction between measurement accuracy and reception reliability.
2Device complexity
If UE devices use a fixed antenna panel for reception, then device complexity is reduced, but signal quality may be suboptimal due to physical obstructions or orientation
Solution Approach 1:
The patent implements dynamic antenna panel selection where the UE can switch between a first antenna panel and a second antenna panel based on real-time signal quality conditions. When the first antenna panel experiences physical obstructions or suboptimal orientation, the system dynamically switches to the second antenna panel for receiving scheduling information. This dynamic approach maintains high reception reliability without requiring complex real-time optimization algorithms, as the switching behavior is triggered by predefined conditions.

A system, apparatus, method, and non-transitory computer readable medium for protecting critical data receptions by a user equipment (UE) device may include a UE device which is caused to, receive data reception priority configuration information from the serving RAN node, the data reception priority configuration information including designating a scheduling information priority time window, and receive scheduling information from the serving RAN node using a first antenna panel of one or more antenna panels during the scheduling information priority time window based on the data reception priority configuration information and signal quality measurements corresponding to each antenna panel of the one or more antenna panels.
