  • Publication number: 20150349870
    Abstract: Dynamic antenna switching based on weighted signal to noise ratio (SNR). A wireless device may include multiple antennas. SNR at each active antenna may be calculated. An antenna-specific weight may be applied to each antenna's SNR. The antenna-specific weights may further be radio specific and/or transmit or receive specific in some cases. Antenna selection (possibly just for a specific radio and/or for transmit or receive operations, depending on the specificity of the antenna weights), including potentially switching which antenna is used, may be based on the resulting weighted SNR values for each antenna. If the antenna-specific weights are radio specific and/or transmit or receive operation specific, the method may be performed multiple times with different antenna-specific weights to select antenna(s) for different radios and/or for other operations.

  • Publication number: 20150163828
    Abstract: A method and apparatus are provided for conducting peer-to-peer communications while channel hopping among two or more wireless channels, at least one of which is a restricted channel. One type of restricted channel requires the use of DFS (Dynamic Frequency Selection) or a similar scheme for avoiding use of the channel during certain circumstances (e.g., for radar avoidance). Communicating peers may synchronize a channel-hopping sequence with TBTTs (Target Beacon Transmission Times) of the restricted channel(s), so that they switch to such a channel in time to capture a beacon and determine whether the channel is free. If the channel is free, or if no beacon is received, they may immediately begin or resume their communications. They may also quiesce just before another TBTT so as to capture that beacon. Thus, the peer-to-peer communications do not diminish a peer device's ability to receive and comply with channel switch announcements.
