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 (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.

Abstract: A method and an apparatus for self-interference cancellation in a communication device. The communication device includes an antenna configured to transmit a transmit signal and receive a receive signal through a duplexer in FDD communications, a first analog to digital converter (ADC) configured to convert the receive signal from analog to digital, a coupler configured to couple a sample of the transmit signal to a second ADC, which is configured to convert the sample of the transmit signal from analog to digital, and self-interference cancellation circuitry configured to process the digital sample of the transmit signal to generate a self-interference cancellation signal and apply the self-interference cancellation signal to the digital receive signal to cancel an amount of interference induced in the receive signal by the transmit signal. The SIC process provides additional isolation between TX signal and RX signal. The additional isolation could be utilized to relief the isolation requirement for the duplexer, reducing the cost and form factor of the duplexer.

Abstract: A wearable wireless communication device comprises a transceiver positioned on a first side of the device, the transceiver comprising a first antenna configured to receive radio frequency (RF) signals transmitted toward the first side of the device. The device is wearable about an object that attenuates reception, by the first antenna, of RF signals transmitted toward a second side of the device. The device further comprises a waveguide electromagnetically coupled to the transceiver, the waveguide terminating in at least a second antenna positioned on the second side of the device. The second antenna is configured to receive the RF signals transmitted toward the second side of the device. The waveguide is shaped to direct received RF signals around the object to the transceiver. The object may in some embodiments be a piece of human anatomy.
