Abstract: For example, a first Enhanced Directional Multi-Gigabit (DMG) (EDMG) station (STA) may be configured to exchange first and second Beam Refinement Protocol (BRP) setup frames with a second EDMG STA to initiate a BRP Transmit Sector Sweep (TXSS) over an aggregated channel bandwidth including an aggregation of a primary channel and a secondary channel in a frequency band above 45 GHz; during the BRP TXSS, transmit a plurality of BRP frames to the second EDMG STA over the primary channel and the secondary channel according to an EDMG control mode; determine a transmit beamforming configuration over the aggregated channel bandwidth based on BRP feedback from the second EDMG STA; and transmit an EDMG Physical Layer (PHY) Protocol Data Unit (PPDU) to the second EDMG STA over the aggregated channel bandwidth based on the transmit beamforming configuration.

Abstract: 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.

Abstract: This disclosure describes systems, methods, and devices related to bandwidth and primary channel indication. A device may encode an extended directional multi-gigabit (EDMG) field with one or more indications of a primary channel ID, a bandwidth value, or a channel ID for transmission over a wireless communication channel associated with the channel ID. The device may cause the EDMG field to be wirelessly transmitted to a first device over the wireless communication channel.
