Abstract: A SmarterFi gateway integrates a WiFi access point and smart repeater, and executes a method therefor. The method includes receiving, from a user equipment (UE) via a first wireless communication channel, wireless fidelity (WiFi) signals that include information indicating a location of the UE. The WiFi signals are received by a transceiver that includes a first antenna array for communication with the UE, and a second antenna array for communication with a gNB. The method includes transmitting, to the gNB via the second antenna array, uplink data and control information that includes the UE location information. The method includes receiving, from the gNB via the second antenna array, downlink information intended for the UE. The method includes forward-transmitting, to the UE via a second wireless communication channel, the downlink information via a beam formed at the first antenna array to serve the UE at the location of the UE.

Abstract: A method for real-time THz sensing using true time delay (TTD) is implemented by a base station and includes transmitting, by a transceiver that includes TDD elements and phase shifters configured in the transceiver, simultaneous frequency dependent (SFD) beams to scan an environment at a first granularity to detect a spatial cluster target. Each of the SFD beams corresponds to a different phase angle and different frequency. The method includes determining, among the SFD beams, a subset of beams that detected the spatial cluster target. The method includes beam switching, by the transceiver, using time division multiplexing (TDM) and a TDM bandwidth to scan a portion of the environment at phase angles corresponding to the subset of beams and at a second granularity finer than the first granularity. The method includes combining data received from the SFD beams, by multiple threads that concurrently process data received from the SFD beams.

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.
