Beam Reporting for Multi-Panel UE Scheduling Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When user equipment (UE) with multiple antenna panels sends a beam report to the network, the signaling overhead increases due to inclusion of antenna panel information, and the network may schedule channels based on inactive panels, leading to data transmission interruptions due to insufficient time for antenna panel switching.
Innovation Solution
A method and apparatus for sending and receiving beam reports that associate beam reports with specific antenna panels, using configuration information to manage reporting and ensure active panel usage, reducing signaling overhead and minimizing switching delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If antenna panel information (antenna panel ID) is added to the beam report, then the network can learn the correspondence between SSBRI/CRI and antenna panel, but the signaling overhead of reporting is increased
Solution Approach 1:
The patent extracts only the essential antenna panel identification information from the beam report, rather than transmitting complete antenna panel configurations. This selective extraction maintains the necessary correspondence information while significantly reducing the signaling overhead burden on the network interface.
Solution Approach 2:
The patent applies local quality by providing detailed antenna panel information only where specifically needed (in the beam report for correspondence tracking), while keeping other portions of the communication streamlined. This targeted information provision optimizes the balance between network knowledge and signaling efficiency.
2Adaptability or versatility
If the network schedules a channel based on beam information from an inactive antenna panel, then scheduling flexibility is improved, but data transmission is interrupted due to insufficient time for antenna panel switching
Solution Approach 1:
The patent implements preliminary action by having the UE prepare and report beam information from multiple antenna panels in advance, including potential future active panels. This allows the network to schedule channels based on pre-evaluated beam information without causing transmission interruptions, as the switching decisions are already optimized beforehand.
Solution Approach 2:
The patent establishes a feedback mechanism where the UE continuously reports beam measurement results from different antenna panels to the network. This feedback loop enables the network to make informed scheduling decisions that account for antenna panel switching requirements, maintaining both scheduling flexibility and transmission reliability through real-time adaptation.
