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: Embodiments include systems and methods for managing an adaptive interference filter performed by a device processor of a mobile communication device. A device processor may determine whether a transmission power from the mobile communication device is greater than or equal to a transmit power threshold. The device processor may determine whether a ratio of interference in a received signal to a level of the received signal including noise (interference ratio) is greater than or equal to an interference ratio threshold in response to determining that the transmission power is greater than or equal to the transmit power threshold. The device processor may perform interference cancellation with the adaptive interference filter in response to determining that the interference ratio is greater than or equal to the interference ratio threshold. In some embodiments the adaptive interference filter may be a non-linear interference cancellation filter.

Abstract: Disclosed is non-linear interference cancellation (NLIC) on a victim receiver in a communication system in which there is self-jamming interference from multiple aggressor transmitters. The victim receiver may implement cascaded NLIC operations using multiple interference signals in succession to remove the multiple interference signals from the Rx signal and to cancel or mitigate the self-jamming interference. The reconstruction and removal of the interference signals may be ordered based on the expected level of interference from the interference signals on the desired Rx signal. The victim receiver may first perform NLIC operation using the Tx signal from the transmitter aggressor estimated to generate the strongest interference signal to remove the strongest interference signal from the Rx signal first. The victim receiver may perform NLIC operation on the TX signal from the next strongest transmitter aggressor, and so on, to remove interference signals of multiple aggressor transmitters from the Rx signal.
Abstract translation: 公开了在来自多个攻击者发射机的自身干扰的通信系统中的受害者接收机上的非线性干扰消除（NLIC）。 受害者接收机可以使用多个干扰信号来连续地实现级联的NLIC操作，以从Rx信号中去除多个干扰信号并消除或减轻自干扰干扰。 干扰信号的重建和去除可以基于期望的Rx信号上来自干扰信号的预期的干扰水平来排序。 受害者接收机可以首先使用来自发射机攻击者的Tx信号来执行NLIC操作，以发射最强的干扰信号，以首先从Rx信号去除最强的干扰信号。 受害者接收机可以对来自下一个最强的发射机攻击者的TX信号执行NLIC操作，以此类推，以从Rx信号中去除多个攻击者发射机的干扰信号。

Abstract: In some aspects, a radar device may receive a received signal comprising a reflected frequency modulated continuous wave (FMCW) radar signal and interference. The radar device may identify the reflected FMCW radar signal based at least in part on performing a phase based search procedure to facilitate removing the interference from the received signal. The radar device may perform an action based at least in part on a characteristic of the identified reflected FMCW radar signal. Numerous other aspects are described.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile device to address maximum permissible exposure (MPE) proximity sensor failure. A mobile device may include a maximum permissible exposure (MPE) sensor control unit to actively monitor signals associated with proper operation of the MPE proximity sensors. Upon detecting an anomaly in any of these signals, such as a value drop below a given threshold, an MPE sensor control Unit will inform an AP (application processor, or other processor or controller) which in turn trigger display of a warning message on the display of the mobile device or the issuance of other warnings such an audible or tactile alert to inform the end user about the maximum permissible exposure (MPE) proximity sensor malfunction and/or notify the end use of a condition resulting in deactivation of the 5G new radio transceiver.

Abstract: Certain embodiments are directed to techniques (e.g., a device, a method, a memory or non-transitory computer readable medium storing code or instructions executable by one or more processors) for object detection and three-dimensional reconstruction of objects using coordinated beam scanning. The disclosed techniques teach coordinated beam scanning that can be used for both detecting proximity to personnel in addition to detecting objects for three-dimensional object reconstructions. The techniques form one or more millimeter wave beam that can be electronically steered by adjusting the phase of the various antenna elements. The techniques can include saving the plurality of grid points for which the object is detected to a memory for detecting a range to the object for Maximum Permitted Exposure (MPE) limit monitoring and three-dimensional object reconstruction.
