Abstract: This disclosure describes methods, apparatuses, and systems related to network allocation vectors. A device is disclosed that may determine a first length of time corresponding to a first spatial reuse transmit opportunity (SR-TxOP) time period. The device may determine a second length of time corresponding to a transmit opportunity (TxOP) time period that starts when a request to send (RTS) frame is transmitted and ends after the first length of time ends. The device may cause to transmit the RTS frame, over the channel, to a first device. The device may determine that a clear to send (CTS) frame is received from the first device, the CTS frame comprising a first duration field equal to having a third length of time corresponding to a second transmission opportunity (SR-TxOP). The device may determine that the third length of time corresponds to a length of time between when the CTS frame was transmitted and when the first length of time ends. The device may determine that the third length of time is less than the second length of time. The device may cause to transmit a CTS to self frame, over the channel, comprising a second duration field equal to having a fourth length of time, wherein the fourth length of time corresponds to a length of time between when the CTS to self frame is transmitted and when the first length of time ends.

Abstract: Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of wireless transmission over a bonded channel. For example, a wireless station may be configured to determine a Clear Channel Assessment (CCA) busy state of a secondary channel in a directional wireless communication band upon detecting transmission of a first packet over the secondary channel; to determine a CCA idle state of the secondary channel upon detecting transmission of a second packet indicating an end of a transmission sequence including the first packet; and to process transmission of a wireless transmission over a bonded channel including a primary channel and the secondary channel, if the CCA state of the secondary channel and a CCA state of the primary channel are idle during at least a back-off and an InterFrame Space (IFS).
