摘要： Methods and apparatus for selectively switching one or more antennas in a multiple-input, multiple-output (MIMO) antenna array so as to mitigate interference with another RF interface within the same space-constrained device, based on radio frequency isolation. In one embodiment, the MIMO interface comprises a WLAN interface having a 2x2 or 3x3 array of antennae which are placed in a wireless device in an asymmetric fashion with respect to the antenna of the second interface, and the other interface comprises a PAN (e.g., Bluetooth) interface operating in an overlapping frequency band (e.g., ISM band). When both interfaces are operating, interference is mitigated through selectively switching off one or more of the MEVIO antennae, and using the remaining antenna(e) having the best isolation from the Bluetooth antennae. This approach allows simultaneous operation of both interferences without significant degradation to user experience or the operation of either interface, and may also provide power savings critical to mobile device battery longevity.

摘要： 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.

摘要： Methods and apparatus for providing primary transport service discovery information over one or more alternate transports that are not normally associated with the primary transport services. In one embodiment, the primary transport comprises a first wireless interface (e.g., Bluetooth), and the alternate transport comprises a second wireless interface (e.g., WiFi or WiMAX). Service profile information relating to the primary transport is broadcast to other users over the alternate transport in a more efficient and streamlined manner than that available on the primary transport. The other users store this service profile information so that it can be subsequently accessed for service profile discovery of the transmitting device by those other devices, thereby obviating subsequent transfer of the data over any transport (primary or alternate).
摘要翻译：用于通过一般或不与主要运输服务相关联的一个或多个替代运输提供主要运输服务发现信息的方法和装置。在一个实施例中，主传输包括第一无线接口（例如，蓝牙），并且备用传输包括第二无线接口（例如，WiFi或WiMAX）。与主要运输相关的服务简档信息以比主要运输上可用的更有效和流畅的方式通过备用运输方式向其他用户广播。其他用户存储该服务简档信息，使得其随后可被其他设备的发送设备的服务配置文件发现访问，从而避免随后通过任何传输（主要或备用）传输数据。
