Systems, methods, and devices enhance performance of collocated transceivers in wireless devices. Methods include identifying, using a processing device, an assertion of a radio frequency (RF) active signal, canceling activity of a first transceiver in response to identifying the assertion of the RF active signal, the RF active signal being associated with a second transceiver collocated with the first transceiver, and generating, using the processing device, a network allocation vector (NAV) reset signal in response to identifying a de-assertion of the RF active signal, the NAV reset signal resetting a timer of a wireless device comprising the first transceiver and the second transceiver.

Systems, methods, and devices for protection management-based coexistence enhancement in wireless devices

Systems, methods, and devices implement enhanced coexistence of radios within wireless devices. Methods include receiving a data packet at a wireless device, the data packet having a packet structure, the wireless device comprising a first wireless radio collocated with a second wireless radio, and identifying one or more features of the data packet based, at least in part, on the packet structure of the data packet. Methods further include updating a medium access grant signal associated with the second wireless radio based, at least in part, on the one or more features of the data packet, the medium access grant signal determining which of the first or second wireless radios has access to a communications medium.

Systems, methods, and devices for coexistence enhancement using acknowledgment signals in wireless devices

Systems, methods, and devices predict activity of wireless devices. Methods include identifying one or more conditions indicating aperiodic activity will occur at a first radio, the first radio being a wireless radio compatible with a first wireless communications protocol, and receiving, at a second radio, timing information associated with the first radio via an interface between the first radio and the second radio, the second radio being a wireless radio compatible with a second wireless communications protocol, the first radio and the second radio being collocated in a wireless device. Methods also include scheduling wireless activity of the second radio based, at least in part, on the timing information.

Enhanced prediction of timing of activity for wireless devices

Systems, methods, and devices enhance performance of collocated transceivers in wireless devices. Methods include determining, using a processing device comprising processing elements, a transmit power for a first transceiver of a wireless device, and determining, using the processing device, a coding rate for a second transceiver of the wireless device based, at least in part, on the determined transmit power, the first transceiver being collocated with the second transceiver. Methods also include determining, using the processing device, a transmission rate for the second transceiver based, at least in part, on the determined coding rate.

Systems, methods, and devices for transmission rate-based coexistence enhancement in wireless devices

Systems, methods, and devices improve medium usage of wireless devices. Methods include determining, using one or more processors, multiple protection frames should be used for a first wireless radio and a second wireless radio based, at least in part, on an interference parameter, wherein the first wireless radio and the second wireless radio are collocated in a same wireless device. Methods also include determining, using the one or more processors, one or more transmission parameters associated at least one of the wireless radios, the one or more transmission parameters representing a first duty cycle of the first wireless radio and a second duty cycle of the second wireless radio. Methods further include determining, using the one or more processors, a number of protection frames and a protection frame duration based, at least in part, on the one or more transmission parameters.

Enhanced transmission medium usage for collocated wireless devices

The embodiments described herein are directed at techniques to sharing a transmission medium in a Bluetooth transceiver/WLAN transceiver combination device. A first device may receive a request from a second device to use the wireless transmission medium. The second device may also transmit timing data to the first device. The first device may determine a period of time to allow the second device to use the wireless transmission medium based on the timing data.

Sharing transmission mediums in WiFi-Bluetooth combination systems

One example of a device includes a Bluetooth transceiver, a Wireless Local Area Network (WLAN) transceiver, and a controller. The WLAN transceiver is proximate the Bluetooth transceiver. The controller is communicatively coupled to the Bluetooth transceiver and the WLAN transceiver. The controller is configured to adjust a cell size of the WLAN transceiver or the Bluetooth transceiver to reduce interference between WLAN transceiver traffic and Bluetooth transceiver traffic.
