Wireless Beam Reporting Across Multiple Time Instances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in beam management scenarios is how a terminal device efficiently reports inference results for multiple time instances, particularly when the strong beams at different time instances differ, leading to inefficiencies in signaling and resource utilization.
Innovation Solution
A method where a first node performs measurements on a first resource set at multiple first-type time instances and transmits information indicating N second-type time instances and corresponding beam information, allowing for efficient reporting of strong beam information across multiple time instances, thereby reducing signaling overhead and improving resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the terminal device reports inference results for multiple time instances separately, then the beam management accuracy is improved, but the signaling overhead increases
Solution Approach 1:
The patent combines multiple separate beam inference results across different time instances into a single integrated feedback message. The terminal device reports beam information for multiple time instances simultaneously rather than separately, reducing the number of signaling exchanges while maintaining comprehensive beam management data.
Solution Approach 2:
The terminal device performs measurements and generates beam inference results in advance for multiple time instances before actual beam switching occurs. This preliminary preparation allows the device to report beam information proactively, reducing real-time signaling overhead while ensuring accurate beam management decisions are made.
2Measurement precision
If the terminal device reports detailed beam information for all time instances, then the beam selection accuracy is improved, but the resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies different reporting strategies for different time instances based on local characteristics. The terminal device identifies which time instances have significant beam changes and reports detailed beam information only for those critical instances, while using simplified reporting for stable periods, thus optimizing resource utilization.
Solution Approach 2:
The terminal device selectively reports beam information for a subset of time instances rather than all instances. By identifying and reporting only the essential time instances where beam changes are significant, the system achieves sufficient beam selection accuracy without the resource overhead of reporting every single time instance.

AI summary
A method and a device in a node for wireless communications are provided. The method includes: receiving first configuration signaling, the first configuration signaling indicating a first resource set; performing measurement on the first resource set, the first resource set being located on multiple first-type time instances; transmitting first information, the first information indicating N second-type time instances and multiple pieces of second-type beam information. The multiple first-type time instances precede the N second-type time instances, and N is a positive integer. A measurement result for the first resource set is used to determine the multiple pieces of second-type beam information. The multiple pieces of second-type beam information correspond to the N second-type time instances.
