Beam Report Configuration for Lower CMR Signaling Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face increased processing overhead and latency due to beam reporting schemes, particularly in the context of 3GPP Release 17 features like group-based beam reporting and panel selection, which incur unnecessary signaling and resource conflicts.
Innovation Solution
Implement methods to reduce overhead and latency by optimizing beam reporting configurations, including selective CRI reporting, parallel processing of CMR sets, and efficient panel selection, using techniques such as non-reporting of CRIs for repeated CMR sets, parallel processing of CMR sets, and reduced panel type signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If group-based beam reporting and panel selection features are implemented, then beam quality assessment capability is improved, but processing overhead and latency increase
Solution Approach 1:
The patent extracts and eliminates redundant CRI reporting for CMR sets with repetition parameter set to ON. Since these sets transmit identical CSI-RS resources, reporting CRI for all sets would be redundant. The invention selectively omits CRI reporting only for repeated sets while maintaining it for non-repeated sets, thereby reducing processing overhead and latency without compromising beam quality assessment capability.
2Loss of information
If CRI reporting is performed for all CMR sets, then complete beam measurement information is provided, but signaling overhead increases
Solution Approach 1:
The patent removes redundant CRI signaling elements from the beam report. By identifying CMR sets with repetition parameter ON (indicating identical CSI-RS resources), the invention extracts only the necessary CRI information for non-repeated sets, eliminating duplicate reporting while preserving complete beam measurement information for diverse beam sets.
Solution Approach 2:
Instead of reporting CRI for all CMR sets (excessive action), the patent applies partial action by reporting CRI only for CMR sets with repetition parameter OFF. This selective approach provides sufficient beam measurement information for beam selection while significantly reducing signaling overhead associated with redundant CRI reports.
3Measurement precision
If multiple CMR sets are processed sequentially, then measurement accuracy is maintained, but processing time increases
Solution Approach 1:
The patent segments the processing of CMR sets into two categories: those with repetition parameter ON and those with repetition parameter OFF. This segmentation allows the UE to identify and handle redundant sets efficiently, processing only necessary CRI reports while maintaining measurement accuracy for all beam sets through selective reporting.

AI summary
The disclosure relates to a method to be performed by a user equipment (UE). The method includes: receiving, from a base station, a beam report configuration that configures the UE to report measurements for a predetermined number of beam pairs, wherein the one or more beam pairs are arranged in a first Channel Measurement Resource (CMR) set and a second CMR set; determining that the first CMR set corresponds to a first repetition parameter and the second CMR set corresponds to a second repetition parameter; and transmitting, based on the first and second repetition parameters, a beam report to the base station. The disclosure also relates to another method as well as a UE.
