Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional interference measurement resources are used for beam management, then the system can perform basic interference measurement, but the measurement precision and interference management effectiveness are insufficient
Solution Approach 1:
The patent introduces virtual interference measurement resources that are logical copies rather than physical transmission resources. These virtual IMRs enable the UE to measure interference based on configured parameters without requiring actual transmission of interference measurement signals, thereby improving measurement precision while reducing the complexity of resource allocation and transmission management.
Solution Approach 2:
The patent uses a network entity as an intermediary to configure and manage the virtual interference measurement resources. The network entity provides the configuration information that enables the UE to accurately measure interference without direct physical interference transmission, facilitating precise interference management through coordinated control.
2Measurement precision
If physical interference measurement resources are transmitted for beam management, then accurate interference measurement can be achieved, but system resources are consumed and transmission overhead increases
Solution Approach 1:
The patent creates virtual copies of interference measurement resources that do not require physical transmission. The UE receives configuration information from the network entity and measures interference based on this configured information, eliminating the need to transmit actual interference measurement signals and thereby saving transmission energy while maintaining measurement accuracy.
Solution Approach 2:
The network entity performs preliminary configuration of the virtual interference measurement resources, providing the UE with the necessary information in advance. This preliminary action eliminates the need for subsequent physical transmission of interference measurement signals, reducing energy consumption while ensuring accurate measurement through pre-configured parameters.
3Adaptability or versatility
If multiple physical interference measurement resources are used for comprehensive beam management, then coverage is improved, but device complexity and resource management burden increase
Solution Approach 1:
The patent designs the virtual interference measurement resources to serve multiple functions through a single configuration mechanism. The network entity configures virtual IMRs that can be used for various beam management scenarios, eliminating the need for separate physical resources for different coverage requirements and thereby reducing device complexity while maintaining comprehensive coverage capability.
Solution Approach 2:
The patent uses virtual copies of interference measurement resources that can be configured to represent different beam management scenarios without requiring separate physical resources. This copying approach allows the system to adapt to various coverage requirements through configuration rather than physical resource multiplication, reducing management complexity.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a channel state information (CSI) report based at least in part on one or more virtual interference measurement resources (IMRs), each virtual IMR representing a logical resource that is used for beam management and is not transmitted. The UE may transmit the CSI report. Numerous other aspects are described.
