Signaling Improved Rx Performance Report for Victim Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR user equipment (UE) specifications result in low data rates due to large nominal maximum sensitivity degradation (MSD) values, as they treat all UEs equally with low-order modulation, failing to account for UE's advanced capabilities, leading to suboptimal receive performance and data rates.
Innovation Solution
A method for signaling an improved receive (Rx) performance report that allows user equipment (UE) to selectively report a subset of K improved Rx performance indicators, specifically the top K largest MSD values, to the network, reducing signaling overhead and enabling better network scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network treats all UEs equally with low-order modulation based on large nominal MSD values, then the reference sensitivity level is satisfied for all UEs, but the data rate is very low
Solution Approach 1:
The patent changes the MSD parameter from large nominal values to smaller actual measured values. By reporting actual MSD values that reflect the UE's true receive performance capability, the network can adjust modulation orders accordingly, enabling higher data rates for UEs with better actual performance while maintaining reliability for those with poorer performance.
Solution Approach 2:
The patent enables differentiated treatment of different UEs based on their individual actual MSD values. Instead of uniform low-order modulation for all UEs, each UE receives modulation scheduling appropriate to its specific receive performance characteristics, allowing high-order modulation for UEs with small MSD values and low-order modulation for those with large MSD values.
2Loss of information
If the UE reports all M improved Rx performance indicators to the network, then the network can fully understand the UE's advanced capability, but the signaling overhead increases
Solution Approach 1:
The patent extracts only the most relevant improved Rx performance indicators from the complete set of M indicators. By selecting and reporting only K indicators that have the greatest impact on receive performance and data rate optimization, the patent reduces signaling overhead while preserving the essential information needed for effective network scheduling.
Solution Approach 2:
The patent applies partial action by reporting a subset K of the full set M of improved Rx performance indicators. This partial reporting is sufficient for the network to make informed scheduling decisions about modulation orders, achieving the necessary information transfer without the excessive overhead of reporting all M indicators.

AI summary
A method for signaling an improved receive (Rx) performance report of victim bands includes: configuring a signaling message to indicate the improved Rx performance report, and sending the signaling message. The improved Rx performance report includes information of K improved Rx performance indicators being only a subset of M improved Rx performance indicators of a user equipment (UE), where K and M are positive integers, M is larger than K, and K is not smaller than one.
