Abstract: Aspects for reducing interference between networks are provided. A signal transmitted by one or more devices in a first network over a communications medium using an unlicensed frequency spectrum is decoded to determine one or more parameters of a packet in the signal. A level of utilization of the communications medium by the one or more devices in the first network can be estimated based at least in part on a signal strength of the signal and the one or more parameters. A period of time for communicating in a second network over the communications medium using the unlicensed frequency spectrum can be adjusted based at least in part on the level of utilization of the communications medium by the first network. In addition, a number of active transmitters over the communications medium can be determined based at least in part on identifying a source entity related to transmission of the signal, and adjusting the time for communicating in the second network can be further based at least in part on the number of active transmitters.

Abstract: The disclosure provides techniques for reducing interference caused by a first device to a second device receiving a satellite-based positioning signal. A device such as a user equipment (UE) or base station (eNB) determines a threshold transmission power for a transmission frequency of the device. The device also determines a signal strength of the satellite-based positioning system signal at the device. The device then controls a transmission property of the device based on the signal strength of the satellite-based positioning system signal when a transmission power of the device at the transmission frequency satisfies the threshold. The device may also determine that reception of the satellite-based positioning system signal by the second device is likely to be affected by a transmission from the device at a transmission power that satisfies the threshold and control the transmission property when reception of the satellite-based positioning system signal is likely to be affected.

Abstract: The present disclosure presents a method and an apparatus for transmitting discovery signaling from a base station. For example, the method may include encoding a wireless fidelity (Wi-Fi) beacon at the base station for transmission and transmitting the encoded Wi-Fi beacon from the base station to one or more neighboring wireless nodes. The Wi-Fi beacon is generated by a Wi-Fi access point (AP) co-located at the base station which is a long term evolution (LTE) or LTE advanced in unlicensed spectrum base station. As such, other wireless nodes can discover the LTE or LTE advanced in unlicensed spectrum base station.
