UE Beam Pair Reporting for Low-Overhead Beam Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in managing beam pair information, as transmitting detailed receive beam information from user equipment (UE) to the network entity can disclose proprietary information about the UE and increase overhead, especially in mobility scenarios.
Innovation Solution
The UE transmits a report with a subset of receive beam information, using a multi-dimensional format that includes non-zero values indicating preferred beam pairs, widths, and gains, allowing the network entity to predict beam pairs without revealing proprietary details and reducing overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE transmits detailed receive beam information to the network entity, then the network entity can accurately predict beam pairs, but the proprietary information of the UE is disclosed and overhead increases
Solution Approach 1:
The patent extracts only the necessary beam pair indication information from the complete receive beam information set. Instead of transmitting all detailed receive beam parameters (which would disclose proprietary information), the UE transmits a condensed report containing only the beam pair indications that are sufficient for network entity to perform accurate beam pair prediction, thereby removing unnecessary information while preserving functionality
Solution Approach 2:
The patent creates a simplified copy of the beam information structure - a report that mirrors the essential beam pair indication functionality without replicating the full proprietary receive beam information. This copy contains only the necessary elements for prediction while omitting the detailed proprietary parameters
2Measurement precision
If the UE transmits detailed receive beam information to the network entity, then the network entity can accurately predict beam pairs, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential beam pair indication elements from the complete receive beam information structure. The transmitted report contains only the necessary beam pair indications for prediction, eliminating redundant detailed parameters and significantly reducing the quantity of transmitted data while maintaining prediction accuracy
Solution Approach 2:
The patent segments the beam information transmission into a structured report with distinct dimensions - one for transmission resources and another for receive beam pointing directions. This segmentation allows selective transmission of only the necessary beam pair combinations rather than transmitting all possible beam information, reducing overall data volume

AI summary
Methods, systems, and devices for wireless communication are described. A user equipment may transmit a report that indicates receive beam information for the UE, where a first dimension of the report is associated with one or more transmission resources of a network entity and a second dimension of the report is associated with one or more receive beam pointing directions at the UE. The UE may receive, from a network entity, an indication of a first receive beam pointing direction of the one or more receive beam pointing directions for a downlink message for the UE based on the report, where the first receive beam pointing direction is associated with a first transmission resource. The UE may receive the downlink message using a receive beam associated with the first receive beam pointing direction based on the received indication from the network entity.
