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: Apparatus, computer readable media, and methods for enhanced beamforming training in a wireless local area network are disclosed. An apparatus of a access point or station is disclosed. The apparatus including processing circuitry where the processing circuitry is configured to encode an EBRP packet comprising a first portion comprising an indication of a first number of transmit antenna training settings (N-TX), and an indication of a second number of receive training subfields per N-TX settings (N-RX), and a second portion comprising a third number of training subfields. The third number may be less than or equal to N-TX times N-RX. The processing circuitry may be configured to cause the first portion of the EBRP packet to be transmitted and cause the second portion to be transmitted, where two or more of the third number of training subfields are to be transmitted simultaneously using different antennas and orthogonal sequences.

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 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.
