Abstract: A communication device can independently determine an interference magnitude component and an interference phase component for interference cancellation. The interference magnitude component may be estimated based, at least in part, on a magnitude polynomial expansion and a transmit signal of the communication device. The interference phase component may be estimated based, at least in part, on a phase polynomial expansion and the transmit signal. The magnitude polynomial expansion and the phase polynomial expansion may have different polynomial terms. The interference signal may be determined based, at least in part, on the interference magnitude component and the interference phase component. At least a portion of the interference signal may be cancelled from a receive signal received by the communication device.

Abstract: A first receiver of a victim communication device may detect a first signal from an aggressor transmitter that potentially may interfere with a second signal intended to be received at a second receiver of the victim communication device. It may be determined whether the first signal interferes with the second signal based, at least in part, on the characteristics of the first signal and the second receiver. If the first signal may interfere with the second signal, the second receiver may implement reconstruction and cancelation of the interference attributable to the first signal.

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. A victim receiver may obtain a non-linear interference cancelation (NLIC) signal from an aggressor transmitter of a communication device. The NLIC signal may be based, at least in part, on a source transmit signal that has been distorted by digital pre-distortion (DPD) at the transmitter. An NLIC unit may reconstruct a cancelation signal based on the NLIC signal. A receiver may remove the cancelation signal from a received signal.

Abstract: Systems and methods for detecting a body part like a human hand near a base station or a user equipment are disclosed. A plurality of radar pulses is transmitted from a communication device in succession and the reflected plurality of radar pulses is received sampled and adaptively processed to remove transmit and receive antenna mutual coupling and clutter from stationary objects near the body part. In one aspect the adaptive processing is accomplished with a single tap adaptive filter. The processed signal may be used to determine if there is a human body part near the communication device allowing the device to determine whether it is safe for the device to transmit a millimeter wave communication signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to be positioned in different possible physical configurations and may identify its current physical configuration based on a modem-based sensor. The UE may transmit a signal from a first antenna element and receive an echo of the signal at a second antenna element different than the first antenna element. The UE may then generate an echo signature for the echo of the signal and determine that the UE is in a first physical configuration (e.g., its current physical configuration) from the possible physical configurations by comparing the generated echo signature to a set of echo signatures that correspond to each of the possible physical configurations. Accordingly, based on the determined first physical configuration, the UE may perform an operating system function that corresponds to the first physical configuration.
