Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing technologies face challenges in efficiently notifying user equipment with multiple antenna panels of the selected uplink transmit beam, leading to increased signaling overhead and system delay, particularly in scenarios where the base station does not consider the antenna panel information during beam configuration.
Innovation Solution
The implementation of a network side equipment that configures and generates configuration information for a transmit beam among multiple antenna panels of user equipment, allowing for the notification of the selected uplink transmit beam, thereby optimizing the uplink transmit beam determination process by reducing unnecessary RRC reconfigurations and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network side equipment uses conventional communication standards to notify the user equipment of the selected uplink transmit beam, then the beam selection process can be standardized, but the signaling overhead and system delay increase significantly when the user equipment has multiple antenna panels
Solution Approach 1:
The patent segments the beam indication process by introducing separate field indicators (first field and second field) that independently indicate beams for different antenna panels. This segmentation allows the network to efficiently notify the UE about multiple beams without requiring extensive reconfiguration signaling, thereby reducing system delay while maintaining adaptability to multi-panel configurations
Solution Approach 2:
The patent adds a new dimension to the beam indication by incorporating antenna panel identification into the beam indication process. Instead of using a single beam indicator, the system now operates in a multi-dimensional space where beams are indicated both by their spatial characteristics and by the antenna panel they belong to, enabling efficient multi-panel beam management
2Measurement precision
If the network side equipment configures transmit beams for multiple antenna panels using detailed RRC reconfiguration, then the beam configuration can be precise and accurate, but the signaling overhead increases
Solution Approach 1:
The patent applies partial action by indicating only the necessary beam information for each antenna panel through compact field indicators rather than full beam configuration parameters. This partial indication approach maintains beam configuration accuracy for multi-panel UEs while significantly reducing the signaling overhead compared to complete RRC reconfiguration
Solution Approach 2:
The patent creates a universal beam indication mechanism that can handle both single-panel and multi-panel UE configurations through the same signaling framework. The first and second fields can universally indicate beams for different antenna panels, eliminating the need for separate detailed configuration procedures and reducing overall signaling overhead
