UE Panel Status Reporting for Antenna Selection and Power Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing multiple active antenna panels of user equipment (UE) for optimal network performance, particularly in scenarios involving power management and interference mitigation.
Innovation Solution
User equipment (UE) generates and transmits a panel status report to a network entity, including metrics such as MPE, PHR, CRI, SSBRI, and RSRP for each active antenna panel, facilitating fast and efficient antenna panel selection and network scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE transmits detailed panel status reports including multiple metrics for each antenna panel, then the network entity can make more informed scheduling decisions and improve overall network performance, but the signaling overhead and processing complexity increase
Solution Approach 1:
The panel status report is segmented into multiple distinct metric types (MPE, PHR, CRI, SSBRI, RSRP) that can be independently measured, reported, and processed. This allows the network entity to selectively use only the necessary metrics for specific scheduling decisions, reducing processing complexity while maintaining scheduling accuracy.
Solution Approach 2:
The panel status report mechanism serves multiple functions simultaneously: it provides power management information (PHR), interference assessment (MPE), channel quality indicators (RSRP, CRI, SSBRI), and scheduling assistance all in a single unified reporting framework. This multi-functionality reduces overall signaling overhead compared to separate reports for each metric type.
2Reliability
If the UE monitors and reports multiple panel-specific metrics including MPE, PHR, CRI, SSBRI, and RSRP, then the network entity can optimize power management and interference mitigation, but the measurement and reporting burden on the UE increases
Solution Approach 1:
Multiple panel-specific metrics (MPE, PHR, CRI, SSBRI, RSRP) that were previously measured and reported separately are merged into a single unified panel status report structure. This consolidation reduces the UE's measurement and reporting burden while providing the network entity with comprehensive information for power management and interference mitigation optimization.
3Productivity
If the network entity receives and processes comprehensive panel status reports from multiple UEs, then scheduling decisions can be optimized for throughput and reliability, but the processing time and computational resources required increase
Solution Approach 1:
The panel status report provides locally-specific quality metrics for each antenna panel (individual MPE, PHR, CRI, SSBRI, and RSRP values per panel) rather than aggregate system-wide metrics. This enables the network entity to make targeted scheduling decisions for specific panels and UEs, optimizing throughput without requiring processing of unnecessary global information, thus reducing overall processing time.

AI summary
Certain aspects of the present disclosure provide techniques for apparatus, methods, processing systems, and computer readable mediums for generating and transmitting a user equipment (UE) initiated panel status report to a network entity. For example, in some cases, certain UE within a wireless communication network may generate a report identifying a number of one or more active antenna panels of the UE and at least one panel-specific metric for each of the one or more active antenna panels and transmit the report to a network entity. The at least one panel-specific metric may include at least one of a maximum permissible emission (MPE) value, a power headroom (PHR value), a channel state information resource indicator (CRI), a synchronization signal block resource indicator (SSBRI), or a reference signal received power (RSRP) related to the respective active antenna panel.
