Abstract: The various embodiments include methods and apparatuses for cancelling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a minimum mean squares interference filter by generating aggressor kernels from the aggressor signals, augmenting the aggressor kernels by weight factors and executing a linear combination of the augmented output, at an intermediate layer to produce intermediate layer outputs. At an output layer, a linear filter function may be executed on the intermediate layer outputs to produce an estimated nonlinear interference used to cancel the nonlinear interference of a victim signal.

Abstract: A wireless communication device including two or more aggressor transmitters and a victim receiver that is adversely affected by intermodulation distortion (IMD) components associated with the signals transmitted by the two or more aggressor transmitters. Because the aggressor transmitters and the victim receiver are located on the same device, the transmit waveforms that contribute to the IMD components are known and available. More specifically, digital baseband samples used by the aggressor transmitters to generate the transmit waveforms are available. These digital baseband samples are used to reconstruct the IMD component on the wireless device. This reconstructed (estimated) IMD component is provided to the victim receiver, and is subtracted from a signal received by the victim receiver, thereby effectively removing the IMD component present in this received signal. An adaptive filter using a Volterra series can be used to estimate the IMD component in response to the transmitter digital baseband samples.

Abstract: A user equipment (UE) may reduce non-linear interference on a signal received at a receiving RAT by using a determined operating parameter of a transmitting radio access technology (RAT) of the user equipment (UE), which transmits a signal according to the operating parameter. The UE may estimate the non-linear interference in digital baseband to a receiving RAT of the UE from a digital baseband portion of the transmitted signal of the transmitting RAT by applying non-linear transformation based on the determined operating parameter of the transmitting RAT and cancel the estimated non-linear interference in baseband from a signal received by the receiving RAT.

Abstract: Self-jamming interference associated with a transmitted signal of an aggressor transmitter may affect a received signal of a victim receiver in a communication device. An aggressor transmitter may provide two or more non-linear interference cancelation (NLIC) signals, including a first NLIC signal and a second NLIC signal. A NLIC unit may reconstruct an interference signal based on a selected one of the first NLIC signal or second NLIC signal. Power of the transmitted signal at the aggressor transmitter may be used to select either the first interference cancelation signal or the second interference cancelation signal. The first and second NLIC signals may differ by the use of digital pre-distortion (DPD) at the aggressor transmitter.

Abstract: An apparatus for is disclosed for mitigating radar-to-radar jamming within a shareable time slot. The apparatus includes a wireless transceiver configured to transmit a first radar signal during a first shareable time slot. The first radar signal has a start time that is delayed relative to a start time of the first shareable time slot by a first time delay. Additionally, the wireless transceiver is configured to receive a first receive signal during the first shareable time slot and detect a potential object based on the first receive signal. Furthermore, the wireless transceiver is configured to transmit, using the first antenna, a second radar signal during a second shareable time slot. The second radar signal has a start time that is delayed relative to a start time of the second shareable time slot by a second time delay. The second time delay is different than the first time delay based on the detection of the potential object.

Abstract: Some disclosed devices include an inertial sensor system, a proximity sensor system, an antenna system configured to transmit and receive radio signals and a control system. The control system may be configured for receiving inertial sensor data from the inertial sensor system and controlling the proximity sensor system and/or the antenna system based, at least in part, on the inertial sensor data. In some examples, the control system may be configured for controlling the proximity sensor system and/or the antenna system based, at least in part, on whether the inertial sensor data indicates that the device is being held, is being carried or is on a person's body (e.g., is in the person's pocket).

Abstract: Aspects of the present disclosure provide a simplified solution for proximity detection of an object in a wireless communication that does not require complex hardware to maintain mutual coupling reference signal. Specifically, in accordance with aspects of the present disclosure, the received signal that may include the mutual coupling signal and target signal may be multiplied by itself to extract the delay information associated with the target signal. The techniques outlined here may provide a greater robustness to variations of mutual coupling induced by phone covers, for example, being added by the user.

Abstract: An apparatus is disclosed for multiplexing radar beat signals. In an example aspect, the apparatus includes an antenna array and a wireless transceiver jointly configured to transmit a radar transmit signal and receive two or more radar receive signals. The two or more radar receive signals represent portions of the radar transmit signal that are reflected by an object. The wireless transceiver comprises a radio-frequency integrated circuit with two or more receive chains and a multiplexing circuit. Each one of the two or more receive chains is configured to generate a radar beat signal by downconverting a respective radar receive signal of the two or more radar receive signals using the radar transmit signal. The multiplexing circuit is coupled to the two or more receive chains and is configured to multiplex the two or more radar beat signals together to generate a composite radar beat signal.

Abstract: Certain aspects of the present disclosure provide techniques for radar management based on interference detected over an air interface. A method that may be performed by a base station (BS) or a user equipment (UE) includes measuring received power at each of a plurality of receive-beams. The method may also include determining whether the measured power received at one or more of the plurality of receive-beams satisfies a threshold condition. If the measured power received at the one or more of the plurality of receive-beams satisfies the threshold condition, the method may also include selecting a directional transmit beam based on a direction of one of the one or more of the plurality of receive-beams that satisfy the threshold condition, and transmitting a radar waveform over the directional transmit beam.
