SINR Measurement Reporting in Wireless CSI Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack efficient methods for obtaining and transmitting signal-to-interference-and-noise ratio (SINR) measurements from user equipment (UE) to network entities, which are crucial for managing inter-cell interference and optimizing channel resources.
Innovation Solution
A method and apparatus for wireless communication that involves receiving a CSI report configuration from a network entity with a report quality parameter set to indicate the use of SINR, triggering the UE to measure SINR, and transmitting the measurement back to the network entity, enabling the network to configure channel measurement resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If SINR measurement and reporting mechanisms are implemented in wireless communication systems, then interference management capability is improved, but system complexity and overhead increase
Solution Approach 1:
The patent segments the SINR measurement and reporting process into distinct components: measurement configuration parameters, measurement procedures, and reporting formats. This allows the system to implement SINR functionality in a modular way, reducing overall system complexity while maintaining interference management capability
Solution Approach 2:
The patent introduces intermediate elements such as measurement configuration parameters and reference signals that mediate between the need for SINR measurement and the system's operational framework. These intermediaries provide structured interfaces that simplify integration into existing wireless communication systems
2Productivity
If SINR measurements are obtained and transmitted from UE to network entity, then channel resource optimization is improved, but communication overhead increases
Solution Approach 1:
The patent extracts only the essential SINR measurement data and relevant configuration parameters for transmission from UE to network entity. By taking out only the necessary information rather than comprehensive channel state data, the system achieves channel resource optimization while minimizing communication overhead
Solution Approach 2:
The patent utilizes parameter changes in the reporting mechanism, allowing the UE to adaptively adjust what SINR measurement data is reported based on configured parameters and current channel conditions. This dynamic parameter adjustment optimizes resource utilization while controlling overhead

AI summary
The present disclosure relates to reported channel state information (CSI) reference signal (RS) resource indicator (CRI)/synchronization signal block resource indicator (SSBRI) and maximum resource number for Layer 1 signal-to-interference-and-noise ratio (SINR). In one aspect, a user equipment (UE) may receive a CSI report configuration that includes a report quantity parameter set to indicate use of a SINR, obtain an SINR measurement, and transmit a CSI report including the SINR measurement to the network entity. In another aspect, a network entity may transmit a CSI report configuration that includes a report quality parameter set to indicate use of a SINR, the report quantity parameter is configured to trigger the UE to measure the SINR of at least one communication channel associated with the network entity, and receive a CSI report including an SINR measurement from the UE.
