Abstract: Methods, systems, and devices are described for adaptive scanning with a multi-radio device. A mobile device may monitor the signal quality of an established communication associated with a first radio (e.g., Long Term Evolution (LTE) radio) to dynamically adapt the measurement activity (e.g., scanning periodicity) of a second radio (e.g., wireless local area network (WLAN) radio) to minimize data transmission interruption.

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: A method of wireless communication includes adjusting a channel quality indicator (CQI) to compensate for coexistence interference experienced between communication resources (such as an LTE radio and a Bluetooth radio). The CQI may be set to zero, falsely indicating to a serving enhanced NodeB that a UE is out of range, thereby creating a gap in LTE operation that may be used by an alternate radio access technology. To compensate for fluctuating interference, the CQI may be adjusted to incorporate average coexistence interference over a period of time. Alternatively, the CQI at a time may incorporate coexistence interference regardless of whether interference is experienced at that specific time. A CQI value may also be boosted to compensate for a CQI backoff. CQI may be adjusted to avoid a spiral of death effect.

Abstract: Methods and apparatuses for reducing interference with co-located radio access technologies (RATs) are described herein. A method includes identifying, by an access point (AP), scheduling information for transmissions to a wireless device for a first RAT and setting a schedule of transmissions from the AP to the wireless device in a second RAT based at least in part on the scheduling information to avoid downlink transmission times for the first RAT. Another example method includes identifying, by a wireless device, scheduling information for transmissions to the wireless device for a first RAT. The method also includes determining a proximities of the wireless device to a first network device of the first RAT and to a second network device of a second RAT. The method further includes forwarding the scheduling information to the second network device of the second RAT based at least in part on the determining the proximities.

Abstract: Techniques are described for wireless communication. A first radio of a user equipment (UE) may receive timing information relating to a transmission of system information over a shared radio frequency spectrum. The first radio may transmit a signal to reserve resources of the shared radio frequency spectrum based at least in part on the timing information. A second radio of the UE may monitor the resources of the shared radio frequency spectrum for the system information. The monitoring may be independent of a successful reservation of the resources of the shared radio frequency spectrum by the first radio.

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: 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.
