Abstract: In wireless communication networks in which pairs of STAs establish direct point-to-point links with each other, RTS-CTS training may be used to make sure that they don't interfere with other such pairs that communicate simultaneously during contention based access periods (CBAP). In some embodiments, two different types of CBAP are described for this. The PCP/AP may separately designate each type of CBAP for those devices using RTS-CTS training and those not using such training. In other embodiments, specific formats and fields are presented for communications involving these features.

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.

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.
