Abstract: Embodiments of an access point (AP), station (STA) and method for channel access are generally described herein. The AP may contend for access to a channel. The contention may be performed in accordance with an omni-directional enhanced distributed channel access function (EDCAF) for transmission within an omni-directional pattern. The contention may be further performed in accordance with a directional EDCAF for transmission to a station (STA) in a directional pattern. The AP may determine whether to transmit within the omni-directional pattern based at least partly on an omni-directional backoff parameter. The AP may further determine whether to transmit in the directional pattern based at least partly on a directional backoff parameter.

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 spatial reuse using quasi-omni and directional clear channel assessment (CCA). A device may use multiple antenna elements in an antenna array to perform both a quasi-omni CCA and a directional CCA during the same time slot. Some embodiments may use different antenna weight vectors to switch the antenna array between quasi-omni and directional CCA. Other embodiments may dedicate some elements of the array to quasi-omni CCA and other elements of the array to directional CCA. The device may use the combination of quasi-omni CCA and directional CCA to determine whether a channel is free for transmitting.
