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.

Dynamic space, frequency and time domain coexistence

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.

Time domain coexistence of RF signals

A circuit includes a first wireless interface circuit that communicates packetized data to a first external device in accordance with a first wireless communication protocol. A second wireless interface circuit communicates packetized data to a second external device in accordance with a second wireless communication protocol. A plurality of signal lines communicate at least four lines of cooperation data between the first wireless interface circuit and the second wireless interface circuit, wherein the cooperation data relates to cooperate transceiving in a common frequency spectrum.
