Abstract: Methods, systems, and devices are described for wireless communication at a UE. The UE may communicate using a shared antenna communicatively coupled with a first radio and a second radio. When the UE identifies an upcoming transition to a sleep mode for the first radio, a tune code for the shared antenna may be adjusted for the second radio. A tune code query may be transmitted to the second radio which may respond with a tune code response. Adjusting the tune code may be based on the tune code response. This allows the second radio to communicate using the shared antenna while the first radio is in the sleep mode. When the UE identifies a transition from the sleep mode for the first radio, the UE may adjust the tune code for the shared antenna for the first radio, allowing the first radio to communicate using the shared antenna.

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: Methods, systems, and devices are described for wireless communication at a wireless device having collocated radios employing different radio access technologies (RATs). For example, a second radio of the wireless device may receive a first scheduling message. The first scheduling message may include information relating to timing, priority, transmission power, and radio capabilities. Using this scheduling message, a determination of whether a first radio employing a first RAT and the second radio employing a second RAT can transmit in parallel may be made. A first transmission on the first radio may be coordinated with a second transmission on the second radio based on the determination of whether the first radio and the second radio can transmit in parallel. A number of data units may be aggregated into an aggregate frame to be transmitted by the second radio. The number of data units may be based on the scheduling message.

Abstract: Methods, systems, and devices are described for adaptively or dynamically tuning a radio frequency (RF) local oscillator (LO) for wireless communications. In one example, a radio may receive an RF signal and the LO of a radio may be tuned to a frequency that is an offset from its reception (RX) center frequency to deal with interference from another signal, such as one being transmitted using a different radio access technology (RAT) than that of the radio. The offset may be determined based upon an effect of the tuning on an attribute of the RF signal. In addition, the offset may be determined based on interference caused by the other signal.

Abstract: A method and apparatus for communicating in a wireless network includes an AP having multiple radios, a first one of which communicates with a nearby client node and a second one of which receives power on another wireless protocol operating in the same or close frequency band as the first radio. The first radio is configured to remotely control the transmit power of the client node so that it doesn't interfere with the reception performance of the second radio. A beacon or probe response frame is used to reduce transmit power of the client node and a CTS2S signal is used to selectively terminate client node transmit power entirely over short periods so that the reception performance of the other wireless device is not severely compromised or desensed by the client node and can be evaluated according to comparative performance criteria such as signal to interference plus noise ratio.

Abstract: The use of multiple radios using different radio access technologies (RATs) on a wireless station can result in interference that can be mitigated by reducing, on a packet-by-packet basis, the bandwidths of communications using one of the RATs. For example, the bandwidth of wireless local area network (WLAN) communications sent or received by a wireless station can be reduced in order to avoid interference with Long-term Evolution (LTE) or LTE-Advanced (LTE-A) communications. A wireless station can determine that only a portion of an interfering bandwidth used by a first radio will interfere with the receipt of communications on a second radio, then the wireless station can dynamically adjust its transmissions on the first radio to only use non-interfering frequencies.

Abstract: Systems and methods are disclosed to implement non-linear interference cancellation (NLIC) across chips or dies in communication systems to cancel or mitigate self-jamming interference. A victim transceiver may receive an analog baseband transmit (Tx) signal from an aggressor transceiver. The analog baseband Tx signal may be tapped from a digital analog converter (DAC) of the aggressor transceiver. Alternatively, the analog baseband Tx signal may be generated by the aggressor transceiver using an auxiliary down-conversion and filtering stage. The victim transceiver may receive a composite baseband Rx signal from the victim transceiver front-end. The composite baseband Rx signal includes the desired Rx signal and an interference signal. The victim transceiver may sample the analog baseband Tx signal to generate a digital signal replica of the analog baseband Tx signal for the NLIC operation to cancel or mitigate the interference signal present in the composite baseband Rx signal.

Abstract: Various embodiments are disclosed for implementing joint non-linear interference cancellation (NLIC) in communication receivers with multiple receiver antennas to cancel or mitigate self-jamming interference from the same aggressor transmitter. A victim receiver may exploit the correlated nature of the interference signals received by the multiple receiver antennas to reduce the computational complexity of an NLIC scheme and improve performance. The victim receiver may select an Rx antenna/Rx chain that experiences the strongest interference from the aggressor transmitter and may perform a full NLIC operation using Tx data from the aggressor transmitter to estimate the strongest interference signal. The NLIC operation may estimate each remaining interference signal by applying a complex coefficient from a single-tap adaptive filter to the estimate of the strongest interference signal. The victim receiver may remove the estimated interference signals from the Rx signals of the respective Rx chains to cancel or mitigate the interference.

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.
