Antenna Panel Segmentation for NR Signal Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In New Radio (NR) systems, especially in frequency range 2 above 6 GHz, channel fading accelerates due to high frequency, leading to insufficient space diversity in information transmission, causing transmission delays and poor signal quality.
Innovation Solution
Activating distinct sets of antenna panels for uplink and downlink transmissions, allowing for advanced configuration and utilization of multiple antenna panels to optimize beam directions and balance load, thereby improving signal quality and resource efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single antenna panel is used for both uplink and downlink transmissions, then device complexity is reduced, but space diversity is insufficient leading to poor signal quality and transmission delays
Solution Approach 1:
The antenna panels are segmented into distinct sets: a first antenna panel set configured for uplink transmissions and a second antenna panel set configured for downlink receptions. This segmentation enables independent optimization of each set for its specific function, improving space diversity and signal quality while maintaining manageable complexity through dedicated configurations.
2Reliability
If multiple antenna panels are activated simultaneously, then space diversity and signal quality improve, but device complexity and resource management increase
Solution Approach 1:
The antenna panels are pre-configured into distinct sets with specific functions assigned beforehand. The first antenna panel set is pre-configured for uplink transmissions and the second antenna panel set is pre-configured for downlink receptions. This preliminary configuration simplifies real-time management while enabling multiple panels to work simultaneously for improved reliability.
3Productivity
If antenna panels are not dedicated to specific directions, then device complexity is reduced, but transmission delays increase due to insufficient beam optimization
Solution Approach 1:
Different antenna panels are assigned different local qualities or characteristics based on their designated functions. The first antenna panel set is optimized with beam configurations suitable for uplink transmissions, while the second antenna panel set is optimized for downlink receptions. This local optimization improves transmission efficiency by ensuring each panel uses the most appropriate beam characteristics for its specific transmission direction.
