CSI Measurement Target Determination for Accurate Multi-Beam Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies lack a clear measurement target when the parameter reportQuantity of a CSI report is set to null, particularly for SINR measurement in multi-cell, multi-user, and multi-beam scenarios, which affects beam measurement and selection accuracy.
Innovation Solution
A method and apparatus for determining a measurement target by receiving configuration information from a network side device, where the parameter reportQuantity of a CSI report is set to null, allowing the terminal device to perform SINR or RSRP measurement, and including RS resource settings for channel and interference measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the parameter reportQuantity of CSI report is set to null, then the terminal device cannot determine the measurement target, but specifying a measurement target increases system complexity
Solution Approach 1:
The terminal device autonomously determines the measurement target based on the configuration information received from the network side device. When reportQuantity is set to null, the terminal device uses pre-configured rules and parameters (such as CSI report type, resource configuration) to self-determine whether to perform RSRP or SINR measurement, without requiring explicit network configuration of the measurement target.
2Measurement precision
If SINR measurement is performed in multi-cell, multi-user, and multi-beam scenes, then beam measurement accuracy is improved, but measurement complexity increases
Solution Approach 1:
The patent segments the measurement process into distinct scenarios (single-cell, multi-cell; single-user, multi-user; single-beam, multi-beam) and provides specific measurement target determination rules for each scenario. This segmentation allows the terminal device to apply simplified rules appropriate to each scenario rather than handling all cases uniformly, reducing overall complexity while maintaining accuracy where needed.
Solution Approach 2:
Different measurement targets and methods are applied locally to different scenarios. For example, in multi-cell multi-user multi-beam scenes where accuracy is critical, SINR measurement is specified; in simpler scenarios, RSRP measurement suffices. This local differentiation optimizes measurement quality where needed while avoiding unnecessary complexity in other cases.
3Device complexity
If measurement target is not specified, then configuration information is simplified, but communication performance in complex environments deteriorates
Solution Approach 1:
The measurement target determination is made dynamic rather than static. The terminal device adaptively determines the measurement target based on the specific scenario conditions (CSI report type, resource configuration, network environment) rather than using a fixed configuration. This dynamic adaptation ensures communication performance is maintained in complex environments while keeping configuration information flexible and manageable.
