Abstract: This disclosure describes systems, methods, and devices related to a multiuser multiple-input and multiple-output (MU-MIMO) setup frame. A device may generate an MU-MIMO setup frame comprising a physical layer (PHY) header and a media access control (MAC) header, the PHY header comprising an indication of a control trailer after the MAC header, the MAC header comprising a first receive address (RA) field comprising one or more first device identifiers (IDs), and the control trailer comprising a second RA field comprising one or more second device IDs. The device may transmit the MU-MIMO setup frame over a directional multi-gigabit (DMG) channel.

Abstract: Methods, computer readable media, and wireless apparatuses are disclosed. The apparatuses including processing circuitry configured to: associate with a master station, decode a frame, where the frame comprises a first duration and a transmitter address and determine that the frame is an intra basic service set (Intra-BSS), an inter (Inter-BSS), or an unclassified frame, where the unclassified frame is the Intra-BSS frame or the Inter-BSS frame. The processing circuitry may be further configured to set an Intra-BSS network allocation vector (NAV) to the first duration if the first duration is longer than a current duration of the Intra-BSS NAV and the frame is determined to be the intra-BSS frame and set the second NAV to the first duration if the first duration is longer than a current duration of the second NAV and the frame is determined to be the inter-BSS frame or the unclassified frame.

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).

Abstract: This disclosure describes methods, apparatus, and systems related to an OFDMA uplink resource allocation framework. An access point may determine a first trigger frame including one or more resource block identifications (RBIDs) associated with one or more resource units on a communication channel. The access point may assign at least one of the one or more RBIDs to at least one device of one or more devices. The access point may cause to send the first trigger frame to the least one device The access point may identify a resource request frame including at least in part a resource request indication associated with the at least one of the one or more RBIDs The access point may assign one of the one or more resource units based at least in part on the resource request indication.

Abstract: This disclosure describes systems, methods, and devices related to reverse direction multi-user multiple input multiple output (MU-MIMO). A device may determine a reverse direction indication to be included in a frame for transmission to one or more first devices in a MU-MIMO communication. The device may cause to wirelessly transmit the frame to a first device of the one or more first devices. The device may identify an acknowledgment frame from the at least one of the first devices based at least in part on the reverse direction indication

Abstract: This disclosure describes systems, methods, and devices related to directional enhanced distributed channel access (EDCA) with interference avoidance. A device may determine a first radio frequency baseband (RF-BB) chain and on a second RF-BB chain associated with one or more antennas of the device. The device may identify a frame from a first device on the first RF-BB chain and the second RF-BB chain. The device may determine the frame is intended for the first RF-BB chain. The device may cause to access a communication channel using the first RF-BB chain. The device may determine an antenna pattern associated with the second RF-BB chain that does not substantially interfere with the first RF-BB chain. The device may cause to access the communication channel using the antenna pattern.
