According to various such techniques, a directional channel access mechanism may be implemented in order to enable improved spatial reuse in a wireless network. In some embodiments, according to the directional channel access mechanism, a wireless communication device may be able to perform multiple concurrent channel accesses in different respective directions. In various embodiments, a wireless communication device utilizing the directional channel access mechanism may transmit in multiple different directions at the same time. In some embodiments, a wireless communication device utilizing the directional channel access mechanism may receive from multiple different directions at the same time. In various embodiments, a wireless communication device utilizing the directional channel access mechanism may transmit in one or more directions and receive from one or more other directions at the same time.

摘要： This disclosure describes methods, apparatus, and systems related to providing a source device more degrees of freedom in the performing CCA, and in using CCA for communicating with neighboring devices. Before accessing the channel, a source device may need to perform carrier sense multiple access with collision avoidance (CSMA/CA), the CSMA/CA additionally comprising CCA. In various embodiments, CCA can be performed either using quasi-omnidirectional receiving antenna(s), or using directional receiving antenna(s). In one embodiment, one or more requisite conditions for performing directional CCA can be specified. In another aspect, sensitivity level adjustments can be provided when performing directional CCA and/or quasi-omnidirectional CCA.

摘要： This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

摘要： Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.

摘要： In some embodiments, a method for mitigating interference between wireless networks is disclosed. A network communications controller, such as a piconet controller that is new to an area, can monitor for and receive inter-network transmission from adjacent networks and the controller can monitor the received transmission and detect a synchronization parameter of the adjacent networks. The parameter can be an inter-network synchronization beacon that is transmitter on a narrowband channel. The controller can select an unoccupied narrowband channel to transmit inter-network synchronization information and the selected an unoccupied wideband channel to conduct intra-network transmissions. The wideband channel can be associated with the narrowband channel. Other embodiments are also disclosed.
