Title:
METHOD AND APPARATUS FOR INTER-BAND DL/UL BEAM CORRESPONDENCE TESTING
Document Type and Number:
WIPO Patent Application WO/2020/206472
Kind Code:
A3
Abstract:
Embodiment methods are provided to test whether a UE supports inter-band beam correspondence between two different frequency bands. In one embodiment, a tester transmits reference signals (RSs) to a UE in a first frequency band, and receives signals from the UE over a plurality of UE transmit beams in a second frequency band different than the first frequency band. The tester selects a beam from the plurality of UE transmit beams that corresponds to effective isotropic radiation power satisfying a predefined criterion, and determines that the UE supports inter-band beam correspondence between the first frequency band and the second frequency band, upon the selected beam satisfying a minimum peak EIRP requirement and a spherical coverage requirement in the second frequency band.
