Abstract  Abstract

The present disclosure relates to a method of selecting parameters for downlink data transmission with a mobile user equipment. A method for selecting at least one parameter for downlink data transmission with a mobile user equipment. The method is performed by a wireless communication base station having multiple antennas configured to wirelessly communicate with mobile user equipment. The method receives an uplink sounding signal from a mobile user equipment. The method determines a plurality of angles of arrival for a corresponding plurality of paths between the mobile user equipment and the plurality of antennas. The method transmits a plurality of downlink sounding signals towards a corresponding angle of arrival of the plurality of angles of arrival. Each downlink sounding signal is for a virtual antenna port of the mobile user equipment. The method receives channel state information. The method composes at least one of a Rank Indicator (RI), a Precoding Matrix Indicator (PMI), or a Modulation and Coding Scheme (MCS) for downlink data transmission to a mobile user equipment.
