Reference Signal Resource Grouping for Multi-Panel Beam Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G New Radio (NR) technology, particularly in the FR2 band, there is a lack of clear definition for beam measurement when a terminal with multiple antenna panels communicates with network-side devices having multiple transmission reception points (TRPs).
Innovation Solution
Configuring reference signal resources with intervals less than a threshold in the time domain for simultaneous transmission and reception using multiple antenna panels, enabling efficient beam management through a method and device that includes receiving and transmitting reference signals on N reference signal resources, where N is greater than 1.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If reference signal resources are configured with small time intervals for simultaneous beam measurement on multiple antenna panels, then beam management efficiency is improved, but signal interference and measurement accuracy may deteriorate
Solution Approach 1:
The patent segments reference signal resources into multiple groups, where each group corresponds to a specific antenna panel. This segmentation allows simultaneous beam measurements on multiple antenna panels using dedicated reference signal resources, improving beam management efficiency while maintaining measurement accuracy through resource isolation.
Solution Approach 2:
The patent introduces a new dimension of resource allocation by associating reference signal resources with specific antenna panels in the spatial domain. This dimensional approach enables parallel beam measurements across multiple panels without time-domain interference, resolving the contradiction between efficiency and accuracy.
2Measurement precision
If reference signal resources are configured with large time intervals to avoid interference, then measurement accuracy is improved, but beam management efficiency deteriorates
Solution Approach 1:
By segmenting reference signal resources into panel-specific groups, the patent eliminates the need for large time intervals between measurements on different panels. Each panel has its own dedicated resources, allowing simultaneous measurements that improve efficiency while maintaining accuracy through resource separation.
Solution Approach 2:
The patent creates a universal reference signal resource configuration framework that can simultaneously serve multiple antenna panels. This multi-functional resource allocation enables parallel beam management operations across different panels without requiring sequential timing, thus improving overall system efficiency.
