  • CHANNEL ESTIMATION FIELDS FOR WIRELESS NETWORKS
    Publication number: 20170317852
    Abstract: This disclosure describes methods, apparatus, and systems related to a channel estimation field (CEF) for various standards, for example, the 802.11ay standard, for single carrier (SC) MIMO channel estimation. In one embodiment, the CEF can use Golay complementary sequences. In another embodiment, the Golay complementary sequences can be defined similar to Golay complementary sequences definitions that can be found in various legacy standards, for example, the legacy 802.11ad standard. Various embodiments of the disclosure can allow channel estimation in the time domain and/or frequency domain, having small or negligible inter-stream interference. Various embodiments of the disclosure can enable an extendable structure for various M×N MIMO configurations, where M and N are positive integers.

  • Methods and arrangements to improve link with out-of-band information
    Patent number: 9801226
    Abstract: Logic may facilitate the establishment and maintenance of a link in a 60 gigahertz band. Logic may determine via out-of-band information that a distance is not likely a reason for failure of a link in the 60 gigahertz band. Logic may determine via out-of-band information that the distance between devices is within a range of the link in the 60 gigahertz band. Logic may determine via out-of-band information that an orientation of one of the devices may be a cause of a poor or failed 60 GHz connection. Logic may display a message to a user related to possible issues with establishing or maintaining a 60 GHz connection. Logic may determine that refining a beamforming directional granularity may improve chances of maintaining a link in the 60 gigahertz band. And logic may synch devices via an out-of-band connection.

  • DEVICE AND METHOD OF PROVIDING GRANT FRAME FOR BANDWIDTH SCHEDULING
    Publication number: 20170202011
    Abstract: Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.
