Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication systems face challenges in efficiently supporting simultaneous multi-panel transmission, which is essential for achieving high data rates and low latency across various services like eMBB, URLLC, and mMTC.
Innovation Solution
A method where a terminal in a wireless communication system receives reference signals from a base station, generates a beam report to support simultaneous multi-panel transmission, and transmits this beam report back to the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If simultaneous multi-panel transmission is implemented to support high data rates and low latency services, then transmission performance is improved, but system complexity increases
Solution Approach 1:
The patent segments the beam reporting process into group-based beam reports that categorize multiple panels into groups. This segmentation allows the system to manage multiple panels through structured group reporting rather than handling each panel individually, thereby supporting high data rates while controlling system complexity through organized information management.
Solution Approach 2:
The patent changes the reporting parameters by introducing group-based beam reporting with specific formats that include panel group identifiers and beam quality metrics. This parameter transformation enables efficient representation of multi-panel transmission states, improving productivity while managing complexity through standardized parameter structures.
2Reliability
If beam reporting is generated for multiple panels to optimize signal strength, then transmission reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent merges beam reporting information from multiple panels into group-based reports. By combining panel identifiers with beam quality metrics in unified report structures, the system maintains reliable signal strength optimization across multiple panels while reducing signaling overhead through consolidated information transmission rather than separate reports for each panel.
Solution Approach 2:
The group-based beam report structure serves multiple functions simultaneously: it identifies panels, reports beam quality, and enables multi-panel transmission optimization. This multi-functionality reduces the need for separate signaling mechanisms, thereby improving reliability while minimizing signaling overhead through a universal reporting framework.
