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: This disclosure describes systems, methods, and devices related to reverse direction duration. A device may establish a multi-user multiple-input multiple-output (MU-MIMO) communication with one or more station devices. The device may determine a frame to be sent to the one or more station devices, wherein the frame includes at least one of a duration field or a reverse direction indication. The device may cause to send the frame to the one or more station devices.

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 power saving by remote wireless mobile devices are provided, in particular by stations (STAs) during downlink (DL) multiple-user multiple-input and multiple-output (MU-MIMO) transmissions in an Institute of Electrical and Electronics Engineers (IEEE) 802.11ay network when reverse direction (RD) transmissions are either enabled and not enabled. Various embodiments enable each STA in a group of STAs to determine an order in which the STAs are requested to send a block acknowledgement (BACK) and which STAs will be granted an RD transmission. Further, a duration of each RD transmission is provided to each STA. Based on the provided information, each STA can determine times to enter a power saving mode. Other embodiments are described and claimed.
