Abstract
A method and a test device for testing the CSI Type 2 channel estimation capability of a DUT are provided. The method includes: a) stimulating certain variance of PMI feedback values from the DUT, especially those belonging to the finer grained Type 2 CSI, b) a statistical collection of one or more PMI reports received through CSI reporting from the DUT during the test execution, c) an identification of Type 1/Type 2 PMI feedback type based on the CSI reports received from the DUT, and d) applying a pass criterion: a minimum threshold of Type 2 specific feedback reports must have been received.
