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: 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 enhanced multiple-input multiple-output (MIMO) beam refinement protocol (BRP) transmit sector sweep (TXSS). A device may establish a first communication link using a first antenna transmit chain of one or more transmit chains of the initiator, wherein the one or more antenna transmit chains further comprise a second antenna transmit chain. The device may initiate a MIMO BRP TXSS over the one or more antenna transmit chains. The device may map a single space-time stream over the one or more antenna transmit chains. The device may cause to send, to a responder device, an enhanced directional multi-gigabit (EDMG) frame using spatial expansion based on the mapping of the single space-time stream. The device may identify a feedback frame from the responder device. The device may determine one or more antenna weight vectors (AWVs) to use in a MIMO phase of the MIMO beamforming training based on the feedback frame.

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.
