Abstract: Briefly, a wireless communication system that includes an Initiator and a Responder to transmit an aggregation of data units in a reverse direction is provided. The Initiator includes a medium access controller capable of allocating a time slot for exchanging one or more transmissions of aggregation of data units with the Responder. The medium access controller includes a channel access scheme, which is able to allocate the time slot for the Responder to transmit the aggregation of data units in the reverse direction, and to grant Originator rights of the Initiator to the Responder within said time slot.

Abstract: Techniques for media access in wireless networks are disclosed. For instance, embodiments may provide a time interval for accessing a wireless communications channel. In addition, embodiments may prevent channel access during the time interval by stations incapable of employing a first channel access technique. This access technique employs an access probability P.

Abstract: A city model generation process. A city model is generated using information about an actual city. A roadway database including segments of roadways is used to generate a city model having grid points corresponding to intersections between the roadway segments. A type of roadway determined from the roadway database information is associated with sets of grid points defining a single roadway. Elevation data is added to the city model using a topographic database. Features, such as a road profile, are added to the roadway using the type. Photographic and zoning information is used to further refine the type of a roadway with a subtype corresponding to features of buildings that may be associated with the roadway. Generic building models and features are associated with the roadways based on the subtypes. Landmark building models are added to the city model to complete the city model.

Abstract: Schemes are disclosed for efficiently training MIMO channels in wireless networks. In at least one embodiment, multiple STAs in a network may share a single channel sounding packet to develop corresponding beamforming matrices or CSI.

Abstract: Embodiments of a wireless communication device and method for dynamic bidirectional aggregation of media-access control (MAC) layer frames in a wireless network are generally described herein. Other embodiments may be described and claimed. In some embodiments, the time between consecutive bursts is dynamically varied based on a MAC channel access delay.

Abstract: An embodiment of the present invention provides an an apparatus, comprising a transmitter capable of sampling a medium in a wireless network and if idle, accessing the medium, and if busy, waiting a random time within a predetermined range and re-sampling the medium. Prior to a first sampling of the medium, the transmitter may wait a first random time within a predetermined range. If the medium is busy the transmitter may continue to sample the medium after waiting subsequent random times within the predetermined range until the medium becomes idle and after the medium becomes idle, may perform a CSMA/CA attempt.

Abstract: In a wireless network in which a central network device (e.g., an access point) communicates with multiple generations of mobile wireless devices that are backward compatible but not forward compatible, each generation of device may be selectively put into a mode that permits contending for the medium or a mode that does not permit contenting for the medium, through the use of packets that are formatted to be recognizable by some generations but not all generations.
