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.

Abstract: This disclosure describes systems, methods, and devices related to link aggregation between devices. A device may encode a multi-band element for transmission using a first interface of one or more interfaces to a first device. The device may cause to send a first link aggregation setup request to the first device including at least in part the multi-band element. The device may identify a first link aggregation setup response from the first device. The device may cause to establish a multi-band link aggregation session with the first device using the first interface.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of beamforming. For example, a responder station may process a received Beam Refinement Protocol (BRP) request including a beam tracking request from an initiator station; and select whether or not to transmit a BRP response including beam tracking feedback, in response to the BRP request, based on a comparison between a time period and a BRP tracking time limit, the time period being based on a timing of the BRP request and a timing of the BRP response.

Abstract: This disclosure describes the generation and implementation of Golay sequences and Golay Sequence Sets (GSSs) for channel estimation in wireless networks. In one embodiment, this disclosure describes an extension of the Golay sequences Ga and Gb defined in various legacy standards to GSSs. In various embodiments, the disclosed GSSs can include a number of Golay complementary pairs (e.g., Ga and Gb). In one embodiment, the disclosed Golay complementary pairs can meet various predetermined design rules and can be used to define enhanced directional multi-gigabit (EDMG) short training field (STF) and/or channel estimation field (CEF) fields for multiple-input and multiple-output (MIMO) transmission.

Abstract: Wireless communication networks may use various techniques, including those that use multiple-access techniques such as multi-user multiple-input multiple-output (MU-MIMO) techniques. In some embodiments, the use of a MU-MIMO setup frame may give a destination STA a chance to select a best antenna weight vector (AWV) based on previous antenna training. In particular, the use of an AWVgroupID may be used to identify a group of one or more STAs that can be the destination STAs of the MU-MIMO setup frame.
