Embodiment Construction

[0014] The following description and figures sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.

[0015] Figure 1A A millimeter wave communication network is shown according to some embodiments. The millimeter wave communication network 100 includes a plurality of millimeter wave communication stations 101-105 using millimeter wave communication. One of these stations, such as communication station 101, may act as a network coordinator, or PCP, to coordinate communications among communication stations 101-105 and control access to the wireless medium. The network coordinator may broadcast a beacon frame indicating the length of the beacon...

Abstract

Embodiments of a millimeter-wave communication station and method for scheduling association beamforming training (A-BFT) with collision avoidance are generally described herein. In some embodiments an initiating station transmits a transmit sector-sweep frame in each of its antenna sectors and receives a reverse transmit sector-sweep frame from two or more unassociated responding stations. The initiating station transmits a sector-sweep feedback frame to each of the responding stations to indicate whether each responding station is to perform beamforming training in a current beacon interval or a subsequent beacon interval. The sector-sweep feedback frame may indicate an order in which the responding stations are to perform beamforming training in subsequent beacon intervals.

Description

technical field [0001] Embodiments relate to millimeter wave communication networks. Some embodiments relate to scheduling associated beamforming training (A-BFT) for collision avoidance in millimeter wave communication networks. Some embodiments relate to wireless personal area networks (WPANs) that communicate using millimeter wave frequencies. Some embodiments relate to millimeter wave communication networks operating according to the standards of the Wireless Gigabit Alliance (WGA). Background technique [0002] Many conventional wireless networks communicate using microwave frequencies, typically in the range between two and ten gigahertz (GHz). These systems generally employ omni-directional or low-directional antennas, generally due to the relatively long wavelengths of the frequencies used. The low directivity of these antennas limits the throughput of such systems, making applications such as real-time video streaming and high-definition television (HDTV) difficu...
