Title:
DYNAMIC OVER-THE-AIR TESTING
Document Type and Number:
WIPO Patent Application WO/2023/115300
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described. A wireless device may be enabled to model a dynamic channel, including channel characteristics, for over-the-air testing of a device. The wireless device may identify multiple test points for a trajectory for a device under test. Adjacent test points may be associated with respective correlation matrix distances, which may indicate a similarity of channel parameters between the adjacent test points. The wireless device may perform an interpolation of each channel parameter between the adjacent test points over respective time periods based on the correlation matrix distances, for example based on whether a correlation matrix distance satisfies or fails to satisfy a threshold. In some cases, the wireless device may transmit, via an antenna and to the device under test within a test chamber, multiple signals which may generate the interpolated channel parameters between the antenna and the device.
