Abstract: 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.
Abstract translation: 描述了用于无线电通信的共存信令方案。 在一个实施例中，一种用于共存信令的方法包括建立与单独接入点或基站的第一通信和第二通信。 该方法还包括确定第一和第二通信的协议定时。 基于各种通信参数，协议定时和识别的干扰条件，该方法包括生成一个或多个优先级信号以管理第一和第二通信。 根据某些方面，可以避免重叠的信道条件，同时保持可接受的通信数据吞吐量。

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: 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.
