Abstract: A cross-division duplex (XDD) system includes an apparatus having a transceiver configured to communicate via an uplink channel and a downlink channel concurrently. The apparatus also includes a transmit antenna, a receive antenna, and a processor. The processor is configured to: estimate a non-linear component corresponding to a transmit path in the transceiver; apply an equalizer function to a received signal; and subtract, in a self-interference cancel (SIC) circuitry, the estimated non-linear component from the equalized signal.

Abstract: A method includes receiving, by a base station, a sounding reference signal (SRS) symbol from a user equipment (UE). The method also includes estimating, by the base station, an uplink (UL) channel from the UE to a full dimensional multiple-input multiple-output (FD-MIMO) base station base band based on the received SRS symbol. The method also includes receiving, by the base station from the UE, an estimate of a downlink (DL) channel from the FD-MIMO base station base band to the UE. The method also includes performing, by the base station, a joint calibration by applying one or more calibration algorithms using channel state information (CSI) of the UL channel and the DL channel.

Abstract: A voice recognition apparatus and a method for providing response information are provided. The voice recognition apparatus according to the present disclosure includes an extractor configured to extract a first utterance element representing a user action and a second utterance element representing an object from a user's utterance voice signal; a domain determiner configured to detect an expansion domain related to the extracted first and second utterance elements based on a hierarchical domain model, and determine at least one candidate domain related to the detected expansion domain as a final domain; a communicator which performs communication with an external apparatus; and a controller configured to control the communicator to transmit information regarding the first and second utterance elements and information regarding the determined final domain.

Abstract: A voice recognition device includes an extractor configured to extract at least one of a first utterance element indicating an execution command and a second utterance element indicating a subject, from a user's voice utterance, a domain determiner configured to determine a current domain to provide response information regarding the voice utterance based on the first and the second utterance elements, and a controller configured to determine a candidate conversation frame to provide the response information regarding the voice utterance on at least one of the current domain and a previous domain based on a conversation state of the current domain, wherein the previous domain is determined from a previous voice utterance of the user.
