US 12,592,754 B2 · Spatial quantization for spherical coverage of user equipment

Abstract

The present disclosure relates generally to the field of wireless communications and, in particular, to techniques for spatially quantizing a spherical coverage of a user equipment (UE) and using the spatially quantized spherical coverage in beamforming at the UE and a network node in a wireless communication system. To this end, the UE transmits, to the network node, location information of the UE and antenna parameter measurements which are taken at least one time in at least one spatial section of the spatially quantized spherical coverage. The network node obtains a signal model based on the UE location information and the antenna parameter measurements. The signal model may be obtained by using a data processing algorithm, e.g., a machine learning algorithm. The signal model is indicative of how reference signals are to be transmitted from the network node to the UE. By so doing, it is possible to optimize the transmission of the reference signals from the network node to the UE, since the network node knows which of the spatial sectors of the spatially quantized spherical coverage of the UE is most suitable for their reception.
