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 device includes circuitry configured to determine characteristics of jammer signals associated with a first wireless protocol of another device. An amount of interference between the jammer signals and a first received signal at the device associated with a second wireless protocol is determined, and the jammer signals are filtered from the second received signal when the amount of interference between the jammer signals and the first received signal is greater than a first predetermined threshold.

Inter-radio communications for scheduling or allocating time-varying frequency resources

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.

Dynamic aggregation for coexistence between wireless transceivers of a host device

A coexistence signaling scheme for radio communications is described. In one embodiment, a method for coexistence signaling includes establishing first communications and second communications with separate access points or base stations. The method further includes determining protocol timings of the first and second communications. Based on various communications parameters, protocol timings, and identified interference conditions, the method includes generating one or more priority signals to manage the first and second communications. According to certain aspects, overlapping channel conditions can be avoided while maintaining acceptable communications data throughput.
