Abstract
Methods and Apparatuses for a transceiver calibration and antenna array operation in a multi-input multi-output (MIMO) system. One of the methods for operation of one or more of the apparatuses comprises sending a calibration signal and a pre-designed training sequence, via a coupling network, receiving a calibration signal and a pre-designed training sequence that is sent by the transceiver array in a time slotted pattern via a coupling network, generating an Rx calibration measurement (R) based on one or more uplink signals received via antenna array and the coupling network, generating a Tx calibration measurement (T) based on receipt of the calibration signal from each of antennas via the coupling network; and performing a joint Tx/Rx (TRx) calibration based on HR, R, and T, where H is a channel response in air interface, R is a channel response of receivers in transceiver array.
