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 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: Methods and systems are described for determining an optimal access point for a client device based on the relative difference between signal strengths of wireless signals received by the client device from access points. In particular, the signal strengths of wireless signals received by a client device from access points are determined without receipt of signal strength and/or transmit power information from the client device. Instead, the signal strength difference value may be determined based on known characteristics of signals transmitted by the access points and known characteristics of signals received by the access points from the client device. This relative difference value may thereafter be used to determine an appropriate access point to provide network access to the client device.

Signal-to-noise type information and committed power information can be employed to determine the ceiling level adjustment. A ceiling level can be a predetermined cap on transmission power for downlink channels between a user equipment and a base station.

While some instances can result in optimized transmission levels below the ceiling, instances can also be accommodated where the ceiling is to be increased.

Abstract: Embodiments allow a wireless device configured to work with the 802.11n/ac standard to work in the communication bands where 802.11p devices operate with little change. Embodiments may receive signals using a receiver adapted for the wider bandwidth 802.11n/ac signals. Embodiments may also increase the sensitivity of the receiver to reduce the likelihood of missing the presence of a lower bandwidth 802.11p signal. When a signal is detected, embodiments may process the incoming signal as if it were an 802.11n/ac signal while also processing incoming signal samples in a way that effectively narrows the receiver bandwidth to identify whether an 802.11p signal is present. If the device detects the presence of an 802.11n/ac signal, it may terminate the 802.11p signal processing and proceed with normal 802.11n/ac operation. If the device detects the presence of an 802.11p signal, it may terminate 802.11n/ac processing and trigger collision avoidance processes.
