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: An access point (AP) configured for wireless local area network (WLAN) sensing is configured to encode a trigger frame (TF) for transmission. The trigger frame allocates resource units (RUs) for receiving high-efficiency (HE) trigger-based (TB) physical-layer protocol data units (PPDUs) (HE TB PPDUs) from a plurality of client devices (non-AP STAs). The trigger frame may solicit each of the client devices to transmit an HE TB PPDU in accordance with an UL OFDMA technique or an UL MU-MIMO technique. The AP may decode the HE TB PPDUs received from the client devices and may estimate channel state information (CSI) for a radio link associated with each of the client devices based on an HE-LTF of an associated one of the HE-TB PPDUs received from one of the client devices. In accordance with these embodiments, the AP may process changes in the CSI of the radio links over time for a WLAN sensing application.

Abstract: An extremely high-throughput (EHT) station (STA) is configured for transmission of a control response frame for rate selection. In response to a frame carried in an EHT PPDU soliciting a control response frame, the EHT STA may calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate, The EHT STA may also encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU, or encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU. A reduction in overhead may be achieved by using an HE SU PPDU or an EHT PPDU instead of a non-HT PPDU to carry a solicited control response frame.
