Abstract: Methods and apparatus for reduction of interference between a plurality of wireless interfaces. In one exemplary embodiment, a device having a first (e.g., Wi-Fi) interface and a second (e.g., Bluetooth) interface monitors interference between its interfaces. A reduction in transmit power of the Wi-Fi module causes a disproportionately larger reduction in undesirable interference experienced at the Bluetooth antennas. For example, when the Bluetooth interface detects interference levels above acceptable thresholds, the Wi-Fi interface adjusts operation of one or more of its transmit chains based on various conditions such as duty cycle, Received Signal Strength Indication (RSSI), etc. Various embodiments of the present invention provide simultaneous operation of WLAN and PAN interfaces, without requiring time division coexistence, by reducing power on a subset of interfering antennas.

Abstract: Methods and apparatus for mitigating the effects of interference between multiple air interfaces located on an electronic device. In one embodiment, the air interfaces include a WLAN interface and PAN (e.g., Bluetooth) interface, and information such as Receiver Signal Strength Index (RSSI) as well as system noise level information are used in order to intelligently execute interference mitigation methodologies, including the selective application of modified frequency selection, variation of transmitter power, and/or change of operating mode (e.g., from multiple-in multiple-out (MIMO) to single-in, single-out (SISO)) so as to reduce isolation requirements between the interfaces. These methods and apparatus are particularly well suited to use cases where the WLAN interface is operating with high data transmission rates. Business methods associated with the foregoing technology are also described.

Abstract translation: 用于减少多个无线接口之间的干扰的方法和装置。 在一个示例性实施例中，具有第一（例如Wi-Fi）接口和第二（例如，蓝牙）接口的设备监视其接口之间的干扰。 Wi-Fi模块的发射功率的降低导致在蓝牙天线上经历的不期望的干扰的不成比例地更大的减少。 例如，当蓝牙接口检测到高于可接受阈值的干扰电平时，Wi-Fi接口根据诸如占空比，接收信号强度指示（RSSI）等各种条件调整其发射链中的一个或多个的操作。各种实施例 本发明通过减少干扰天线子集的功率来提供WLAN和PAN接口的同时操作，而不需要时分共享。
