Abstract  Abstract

A method for at least one parameter of the down-link data transmission selected with the mobile user device. The method is performed by a wireless communication base station the wireless communication base station is configured with a plurality of antennas and wireless communication of mobile user equipment. The method receives the uplink sounding signal from a mobile user equipment. The method determines a plurality of arrival angle a plurality of paths between the mobile user equipment and corresponding to the plurality of antennas. the method towards the direction of angle of arrival corresponding to the plurality of angle of arrival of the transmitted plurality of downlink detection signal. each downlink probe signal is about the virtual antenna port of the mobile user equipment. The method receives channel state information. The method aims to downlink data transmission of mobile user equipment composed of a rank indicator (RI) a precoding matrix indicator (PMI) or modulation and coding scheme (MCS).

A method for selecting at least one parameter for downlink data transmission with a mobile user equipment. The method is executable by a wireless communication base station having multiple antennas configured to communicate wirelessly with the mobile user equipment. The method receives an uplink probing signal from the 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 multiple antennas. The method transmits a plurality of downlink probing signals directionally toward corresponding angles of arrival in the plurality of angles of arrival. Each downlink probing signal is a virtual antenna port with respect to the mobile user equipment. The method receives channel state information. The method composes at least one of a rank indicator (RI) precoding matrix indicator (PMI) or modulating and coding scheme (MCS) for downlink data transmission to the mobile user equipment.
