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 using enhanced acknowledgment and power save. A device may determine a multi-user (MU) multiple-input multiple-output (MIMO) frame associated with a MU-MIMO group. The device may determine a first portion of the MU-MIMO frame associated with the first station device of the MU-MIMO group, wherein the first portion comprises a first indication of a first time offset associated with the first station device. The device may determine a second portion of the MU-MIMO frame associated with the second station device of the MU-MIMO group, wherein the second portion comprises a second indication of a second time offset associated with the second station device. The device may cause to send the MU-MIMO frame to the MU-MIMO group. The device may identify a first acknowledgment from the first station device based on the first time offset.

Abstract: An extremely high-throughput (EHT) station (STA) may encode a null data packet (NDP) announcement frame for transmission to include a high-efficiency (HE) subfield and a Ranging subfield in a Sounding Dialogue Token field. To identify the NDP announcement frame as an EHT NDP announcement frame (i.e., an EHT variant), the EHT STA may set both the HE subfield and the Ranging subfield in the Sounding Dialogue Token field to a value of one. When operating as an EHT access point (AP), the EHT STA may encode a trigger frame to include a Special User Info Field. The Special User Info Field may be identified by a predetermined value as an STA association identifier (AID) value. The use of the predetermined value as the AID value in the Special User Info Field indicates that the trigger frame is an EHT variant and indicates that the trigger frame is being sent by an EHT AP.

Abstract: A wireless communication device, system and method. The device includes a memory, a processing circuitry coupled to the memory and including logic, the processing circuitry to cause communication in an Enhanced Directional Multi-Gigabit (EDMG) network. The processing circuitry may be configured to: activate at least one Radio Frequency (RF) chain of a plurality of RF chains to allow detection of a preamble of a wireless communication and to allow a setting of a Network Allocation Vector (NAV); detect the preamble using the at least one RF chain; set the NAV using the at least one RF chain; maintain a backoff timer for the at least one RF chain; and, in response to a determination that the backoff timer has reached zero, cause a Multiple Input Multiple Output (MIMO) wireless communication in the EDMG network.

Abstract: This disclosure describes systems, methods, and devices related to multiple-input multiple-output (MIMO) channel access. A device may determine one or more time division duplex (TDD) service periods (SPs). The device may determine a directional multi-gigabit (DMG) frame to be sent to a responder device on a channel associated with a MIMO communication. The device may cause to send the DMG frame to the responder device on the channel. The device may establish a MIMO channel access based on sending the DMG frame to the responder device.

Abstract: This disclosure describes systems, methods, and devices related to transmit power control (TPC). A device may identify a link measurement request frame from a first station device. The device may determine, for each transmit chain of the first station device, a TPC action to be performed by the first device. The device may cause to send a link measurement report frame comprising a value indicative of the TPC action for each transmit chain. The device may identify an acknowledgement from the first station device.

Abstract: For example, an EDMG initiator STA of an asymmetric beamforming training may be configured to, during a Beacon Transmission Interval (BTI) in a Beacon Interval (BI), transmit a beacon via a sector of the EDMG initiator STA, the beacon including allocation information to allocate a beamforming training allocation for asymmetric beamforming training of the sector during a Data Transfer Interval (DTI) in the BI after the BTI, the beacon including one or more Receive Training (TRN-R) subfields for the asymmetric beamforming training of the sector; during the beamforming training allocation, to listen on the sector for one or more Sector Sweep (SSW) frames from one or more EDMG responder STAs; and, during the beamforming training allocation, to transmit via the sector a sector acknowledgement (ACK) frame including information based on the one or more SSW frames.
