Abstract: A wireless communication device, system and method. The device includes a memory, and processing circuitry coupled to the memory. The processing circuitry includes logic to: determine a training field length associated with a directional multigigabit (DMG) CTS frame of another wireless communication device; determine a Clear-To-Send time (CTS_Time) parameter based at least in part on the training field length; determine a transmit opportunity (TXOP) continuation timeout for the device based on the CTS_Time parameter; and set a network allocation vector (NA V) for the device based on the TXOP con-tinuation timeout.

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: 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.

Abstract: In Down Link MU-MIMO, an AP transmits to several STAs concurrently. In the mmWave band, directional transmissions are used so it is necessary for both the AP and the STAs to set their antenna arrays (by setting their antenna weight vectors—AWVs) in the best way to receive the transmissions directed to them by the AP and to avoid interference from transmissions directed to other devices. An exemplary embodiment discloses a beamforming training protocol that is capable of generating a set of antenna weight vectors for MU-MIMO operation that at least improves performance of subsequent communications.

Abstract: Methods and apparatus for contention based spatial sharing in wireless communications. An example first wireless communications device includes: a memory to store data for transmission; a priority controller to: determine an estimated transmission time; set a contention window setting based on the estimated transmission time; a media access control to: wait for a timer to expire, a duration of the timer selected based on the contention window setting; and transmit the data when the timer expires.
