    摘要： Exploratory beamforming training techniques for 60 GHz devices are described. In one embodiment, for example, an apparatus may comprise a station (STA) comprising logic, at least a portion of which is in hardware, the logic to identify an exploratory link quality associated with an exploratory beamforming configuration for a directionally-beamformed wireless link, determine whether to revert to a previous beamforming configuration for the directionally-beamformed wireless link based on the exploratory link quality, and in response to a determination to revert to the previous beamforming configuration, send a frame comprising a rollback notification for the directionally-beamformed wireless link. Other embodiments are described and claimed.

    摘要： A method and apparatus for receive beam-forming in an analog domain. A user equipment may perform channel estimation for obtaining a set of channel responses for a plurality of antennas of the UE. The UE may determine a beamforming codeword for receive beamforming based on the set of channel responses. The UE may apply a training codeword to the received signal in analog domain. The training codeword includes phase adjustment coefficients for each antenna and a different training codeword may be applied for each channel observation. The UE may measure a metric for at least one candidate codeword based on the set of channel responses and determine the beamforming codeword based on the metric.

    摘要： Logic may enable communication between stations in the presence of interference. Logic may communicate with the station in the presence of interference, the interference from a communication between other stations comprising a first network allocation vector (NAV) reminder, by entering a mode in which a Control Physical layer (PHY) modulation and coding scheme (MCS) is enabled and a Single Carrier PHY MCS is disabled. Logic may enable the Single Carrier PHY MCS in response to receipt of a clear-to-send (CTS) or an expiration of a CTS timeout. Logic may determine an active time remainder during a Contention-based access period. Logic may determine a time to access a channel in response to receipt of the Denial to Send and based upon a predefined, maximum inactivity time. Logic may remain beamformed while the apparatus is in the Control PHY mode.

    摘要： Beamforming is used in wireless link communication to improve a wireless link through increased channel capacity and diversity by focusing a beam, such as from multiple antennas, in the direction of the receiver. Where the receiver may be capable of measurements relevant to beamforming, more particularly measurements that vary or are otherwise dependent upon changes in beamforming settings, reference to such measurements and corresponding beamforming settings may improve performance. In this Disclosure, a sink device transmits a data stream to a source device, wherein said data stream comprises the position of the sink device. The data stream may further comprise data such as link quality, heading information, or discretized location. The source device stores this data in a memory. When the wireless link deteriorates, the source device assesses its memory to select a candidate beamforming setting with some indicia of success, such as those that correspond closely to the sink device's position, the most recently used beamforming settings, or beamforming settings that previously resulted in a satisfactory wireless link quality.
