    • Various embodiments directed to a radio frequency (RF) environment aware wireless communication device to analyze interference characteristics of at least one interferer in the presence of interference in an RF communications channel and to selectively perform one or more adaptation mechanisms for adjusting properties of a communications protocol based on the interference characteristics of the at least one interferer. The interferer may comprise a non-communicating device (e.g., microwave oven) or a communicating device (e.g., baby monitor, cordless phones, Bluetooth device, etc.) operating within or in the vicinity of a wireless network. The adaptation mechanisms may comprise contention window control to backoff and defer transmission according to a contention window and to leave a backoff counter of the contention window unchanged if the interference is determined to be non-802.11 interference. The adaptation mechanisms may comprise aggressive transmission to transmit over the interference. Other embodiments are described and claimed.
    • 针对无线电频率(RF)环境感知无线通信设备的各种实施例在RF通信信道中存在干扰的情况下分析至少一个干扰源的干扰特性,并且选择性地执行一个或多个适配机制以调整通信协议的属性 基于所述至少一个干扰源的干扰特性。 干扰源可以包括在无线网络内或附近操作的非通信设备(例如,微波炉)或通信设备(例如,婴儿监视器,无绳电话,蓝牙设备等)。 适应机制可以包括竞争窗口控制,以便如果干扰被确定为非802.11干扰,则根据争用窗口来回退和延迟传输,并且使争用窗口的退避计数器保持不变。 适应机制可以包括通过干扰进行传输的主动传输。 描述和要求保护其他实施例。
