Abstract: Embodiments of an enhanced directional multi-gigabit (EDMG) station (STA), access point (AP), and method of communication are generally described herein. The EDMG STA may receive, from the AP, a Link Measurement Request Frame that includes a request for information for time division duplexing (TDD) rate adaptation. The EDMG STA may transmit a Link Measurement Response Frame that includes a Directional Multi Gigabit (DMG) Link Margin element that includes a Rate Adaption Control parameter. The DMG Link Margin element may be configurable to include one or more optional fields for the TDD rate adaptation and transmit power control. The Rate Adaptation Control parameter may indicate: a number of space time streams (STSs) for which information is included in the DMG Link Margin element; and whether the DMG Link Margin element includes the one or more optional fields.

Abstract: Described herein are methods and devices to provide support for a hidden SSID in an 802.11ad or directional multi-gigabit (DMG) wireless network. An access point (AP) of the DMG network may be configured to explicitly signal the hidden SSID configuration by sending probe responses that signal the hidden SSID configuration and/or signaling the hidden SSID configuration in DMG beacons transmitted by the AP.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of power management in a wireless network. For example, a first wireless station may be configured to transmit a frame to a second wireless station during a first beacon interval, the frame including an indication that the first wireless station is to switch to a low power mode; switch to the low power mode; operate at an active mode during an awake window in a second beacon interval subsequent to the first beacon interval; and upon receipt of an announcement traffic indication message (ATIM) from the second wireless station during the awake window, transmit an acknowledgement to the second wireless station, and stay at the active mode to communicate data with the second wireless station.

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: Techniques for interference mitigation in directional multi-gigabit networks are described. In one embodiment, for example, an apparatus may comprise logic, at least a portion of which is in hardware, the logic to send, from a source device, a first reverse direction grant (RDG) indicating that a sink device may transmit to the source device, detect interference with a received sink device data transmission at the source device, select a grant deferral period, and upon conclusion of the grant deferral period, send a second RDG indicating that the sink device may transmit to the source device. Other embodiments are described and claimed.

Abstract: For example, an EDMG STA may be configured to receive an A-MPDU for the EDMG STA in an EDMG MU PPDU from an EDMG MU-MIMO initiator station; to determine, according to an ordered acknowledgement scheme, a Block Acknowledgement (BA) period in which the EDMG STA is to be awake to allow transmission of a BA from the EDMG STA to the EDMG MU-MIMO initiator STA; to allow the EDMG STA to be in a power save mode during a first power save period from a time of an End of Frame (EOF) field in the A-MPDU for the EDMG STA until a beginning of the BA period; to transmit the BA to the EDMG MU-MIMO initiator; and to allow the EDMG STA to be in the power save mode during a second power save period after transmission of the BA.

Abstract: For example, a first STA may be configured to transmit to a second STA a message including a first value to indicate an available memory size at the first STA at a beginning of a TXOP, and a second value to indicate a maximal length of an A-MPDU transmission during the TXOP; to receive an initial A-MPDU from the second STA during the TXOP, a length of the initial A-MPDU is not longer than the first value; to determine a capacity value based on a current available memory size at the first STA, the capacity value to indicate whether the second STA is to be allowed to send to the first STA a subsequent A-MPDU having a length which is not longer than the second value; and to transmit to the second STA an Ack including a buffer capacity field including the capacity value.

Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of communicating a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission. For example, a first wireless communication station may be configured to transmit a Request to Send (RTS) to a second wireless communication station via a plurality of SU MIMO Transmit (Tx) sectors of the first wireless communication station, the RTS to establish a Transmit Opportunity (TXOP) to transmit an SU-MIMO transmission to the second wireless communication station, a control trailer of the RTS including an indication of an intent to transmit the SU-MIMO transmission to the second wireless communication station; and to transmit the SU-MIMO transmission to the second wireless communication station, upon receipt of a Clear to Send (CTS) from the second wireless communication station indicating that the second wireless communication station is ready to receive the SU-MIMO transmission.

Abstract: Devices and methods of for wireless communication in a directional multi-gigabit (DMG) band are generally described. A device can detect a starting point of an awake window (AW). The device can encode a first announcement traffic indication message (ATIM) for directional transmission, after no more than a point coordination function (PCF) interframe space (PIFS) subsequent to the starting point, over a first beamformed link to a first station (STA). The device can encode a second ATIM for directional transmission subsequent to directional transmission of the first ATIM, within the AW and in a different direction than the directional transmission of the first ATIM, over a second beamformed link to a second STA. Other devices, systems and methods are also described.
