    Abstract: Embodiments determine that interference between two radio transmissions is causing, or has the potential to cause, a network device to fail to receive acknowledgement packets. In response to such a determination, the embodiments lower an acknowledgement packet transmission bit rate to increase the likelihood that an acknowledgement packet can be successfully received, thereby avoiding needless retransmission of packets that have been successfully received.

    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: Frequency bands for Industrial Scientific and Medical (ISM) communications are selected to avoid interference with the cellular communication. In one aspect of the disclosure, the frequency bands for Bluetooth/WLAN communication are selected to avoid channels that are within a predetermined distance of a harmonic of a cellular (e.g., wireless wide area network) receive frequency band. That is, a frequency band is selected that is at least a predetermined distance from the cellular receive frequency bands.

    Abstract: Methods, systems, and devices are described for wireless communications in which an unlicensed spectrum may be used for cellular communications (e.g., Long Term Evolution (LTE) communications). More particularly, the described features relate to improving resource management in a multi-radio or multi-modem wireless device by utilizing one radio or modem (e.g., a wireless local area network (WLAN) radio) to inform the operation of another radio or modem (e.g., an LTE radio) co-located on the wireless device. The monitoring radio (e.g., WLAN radio) may scan an unlicensed or shared spectrum for interfering signals (e.g., military, weather, etc.) transmitted on designated channels within the shared spectrum. Upon detection of the interfering signal, the monitoring radio may generate a spectrum analysis of the detected interference and inform the second radio (e.g., LTE radio) to modify its operation based on the spectrum analysis.

    Abstract: Methods, systems, and devices are described for eliminating interference from a convoluted signal comprising several signals of different radio access technologies (RATs), such as a Long Term Evolution (LTE) signal and wireless local area network (WLAN) signal, in an unlicensed or shared radio frequency spectrum band are described. In accordance with the present disclosure, a dual-radio mobile device may utilize a multiple radios to assist in the operation of interference cancellation. Specifically, in some examples, a first radio (e.g., WLAN radio) may process the received convoluted signal to reconstruct a first signal (e.g., WLAN signal). The reconstructed first signal may be utilized by a second radio (e.g., LTE radio) to identify a second signal (e.g., LTE signal) in the received convoluted signal by cancelling or removing the reconstructed first signal from the convoluted signal.

    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.
