Abstract
Operating a cellular multiple-input and multiple-output system including a first device having an antenna array having a plurality of antennas, and a second device having at least two antennas includes a same uplink pilot signal broadcast from each antenna of the second device, and received at the antenna array of the first device. Depending on the received same uplink pilot signal, a first set of first device receiving parameters for the antenna array is determined. From each antenna of the at least two antennas of the second device, a corresponding uplink pilot signal is sent and received at the antenna array of the first device using the first set of first device receiving parameters. At the first device, for each received uplink pilot signal, a corresponding second set of first device receiving parameters is determined depending on the plurality of received orthogonal uplink pilot signals.
