Abstract: Various methods and systems are provided for time domain coexistence of RF signals. In one example, among others, a method includes obtaining access to a WLAN channel during a free period of a coexisting cellular connection, providing a RDG to allow another device to transmit for a duration corresponding to at least a portion of a TXOP, and receiving a transmission during the duration. In another example, a method includes obtaining access to a WLAN channel during a transmission period of a coexisting cellular connection and providing a protection frame to defer transmissions from another device for a duration corresponding to at least a portion of a TXOP. In another example, a method includes determining a shift of a BT transaction based at least in part upon a schedule of cellular communications and shifting at least a portion of the BT transaction based upon the determined shift.

Abstract: Systems and methods for determining whether a companion communication device is beyond a proximity of a primary communication device are provided. In some aspects, a system includes an analysis module configured to determine whether a wireless transaction between the primary communication device and the companion communication device is at a conclusion. The system also includes a communications module configured to emit a sensing signal based on the determination of whether the transaction is at the conclusion. The sensing signal is insufficient to elicit a response from the companion communication device. The system also includes a detection module configured to detect a present parameter associated with the emitted sensing signal. The analysis module is configured to determine a parameter change between the present parameter and a reference parameter, and to determine whether the companion communication device is beyond the proximity of the primary communication device based on the parameter change.

Abstract: Various methods and systems are provided for space, frequency and time domain coexistence of RF signals. In one example, among others, a communication device includes a coexistence manager capable of monitoring operating conditions of a cellular modem and a coexistence assistant capable of monitoring operating conditions of a wireless connectivity unit. The coexistence manager is capable of modifying operation of the modem and/or unit based on an operating condition change. In another example, a method includes detecting a change in antenna isolation and/or operating temperature of a FE filter, determining filtering characteristics of the FE filter based at least in part upon the change, and modifying communications of coexisting communication protocols based at least in part upon the filtering characteristics. In another example, a TX/RX configuration for coexisting communication protocols is determined and communications in a protocol is modified based at least in part upon the TX/RX configuration.
