Abstract: A method includes transmitting, by a transceiver configured to concurrently transmit over multiple transmit paths and receive over multiple receive paths, one or more signals, the transceiver comprising multiple transmit antennas and multiple receive antennas. The method also includes, for at least one of the multiple receive antennas: receiving one or more feedback signals from one or more power amplifiers associated with the one or more transmitted signals; calculating one or more estimated self-interference (SI) signals based on the one or more feedback signals using an equalizer array comprising a predetermined channel model; and subtracting the one or more estimated SI signals from one or more receive signals received at the at least one receive antenna to obtain one or more residual signals.

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.

Abstract: A base station configured to perform a method for self-interference cancelation (SIC) is provided. The method includes transmitting, by a transceiver configured to transmit an uplink channel and a downlink channel concurrently, one or more signals, the transceiver coupled to, or including, a first number of transmit antennas and a second number of receive antennas. The method also includes, for at least one receive antenna of the second number of receive antennas, applying a forward path model including a non-linear component corresponding to a transmit path in the transceiver, and applying an equalizer function to a first signal to be transmitted by at least one transmit antenna of the first number of transmit antennas determine a self-interference (SI) estimate; and subtracting, in SIC circuitry, the SI estimate from the signal received via at least one receive antenna of the second number of receive antennas to obtain an residual signal.

Abstract: An electronic device, a base station, and a method for managing a shared spectrum. The electronic device includes a processor configured to cause the electronic device to obtain coexistence measurement reports (CMRs) from the plurality of BSs; identify interference relationships among the plurality of BSs based on the CMRs; assign a set of BSs to one or more basic allocation units (BAUs) in a plurality of BAUs based on the interference relationships; and transmit a spectrum access grant (SAG) to the set of BSs, wherein the SAG includes BAU assignments for the set of BSs. Each BAU in the plurality of BAUs is a time/frequency unit and the set of BSs includes a primary BS and a secondary BS. The secondary BS can transmit in the one or more BAUs when a transmission of the secondary BS does not interfere with a transmission of the primary BS.
