Abstract
A method for 5G digital beamforming testing includes receiving emulated UE spatial positions. The method includes computing phase vectors for the emulated UEs based on the emulated UE spatial positions and communicating the phase vectors to a DUT. The method includes receiving beam weight sets from the DUT and storing the beam weight sets. The method includes computing scores for the emulated UE spatial positions from the beam weight sets and the phase vectors, and receiving, from the DUT, spatial streams and identifiers of beam weight sets to be used to transmit the spatial streams to the emulated UEs. The method includes identifying, using scores corresponding to the beam weight sets to be used to transmit the spatial streams to the emulated UEs, associations between the spatial streams and the emulated UE spatial positions. The method includes processing data in the spatial streams using the emulated UEs.
