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 (R1) based on one or more uplink signals received via antenna array and the coupling network, generating a Tx calibration measurement (T1) 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, R1, and T1, where H is a channel response in air interface, R is a channel response of receivers in transceiver array."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for calibration and array operation in advanced MIMO system","description":"Methods and Apparatuses for a transceiver calibration and antenna array operation in a multi-input multi-output (MIMO) system.
