20120008568 | DIRECTIONAL MEDIA ACCESS TECHNIQUES WITH SPATIAL REUSE - Techniques are disclosed involving media access. For instance, wireless connections may be assigned into one or more groups. The assignments may be based on interference characteristics. Connection(s) within each of these groups may have acceptable interference characteristics with each other. Further, media access may be granted based on these groups. For example, if a device wishes to communicate across one of the connections, access may be granted for concurrent connections among all connections in the corresponding group. The granting of such access may be performed by a centralized controller device, such as an access point. | 01-12-2012 |
20120071116 | MU MIMO SUPPORT WITH HIGHLY DIRECTIONAL ANTENNAS - In various embodiments, a network controller in a multi-user multiple input multiple output (MU MIMO) network may perform training for directional communications with multiple mobile devices. It may organize the mobile devices into different groups, with all the mobile devices in a single group able to communicate simultaneously with the network controller without excessive interference from each other. Various techniques may be used for such training and grouping. | 03-22-2012 |
20130170427 | PROTOCOL FOR MU MIMO OPERATION IN A WIRELESS NETWORK - Various embodiments of the invention may modify the techniques used in conventional networks, to achieve techniques that are better suited for networks that use highly directional communications. A novel method is described for determining whether a channel in such a network is idle. In addition, various protocols and formats are disclosed that are intended for such a network. | 07-04-2013 |
20140016495 | LINK PREDICTION BASED RE-BEAMFORMING TRIGGERING ALGORITHM FOR 60 GHZ COMMUNICATION LINKS - A system and method are provided to trigger re-beamforming based on an algorithm that assesses various link characteristics. The algorithm is based on the ability of a 60 GHz receiving device to track and feedback a Received Signal Strength Indication (RSSI) to a 60 GHz data packet transmitter. By automatically analyzing RSSI values across a range of data packets, including consecutive data packets, a link degradation trend is predicted. When link degradation crosses, or is predicted to cross, a predetermined threshold, re-beamforming is triggered by the algorithm. Variables in the algorithm and the predetermined thresholds used by the algorithm can be automatically or manually modified to maintain a balance between appropriately triggering the re-beamforming when the conditions arise without unnecessarily triggering the re-beamforming thereby causing unneeded interruptions in regular data flow. | 01-16-2014 |
