    Abstract: This disclosure describes systems, methods, and devices related to analog beamforming for Wi-Fi devices. A device may determine a first analog direction associated with a first antenna of one or more antennas, using an RF chain. The device may determine a second analog direction associated with a second antenna of the one or more antennas, using the RF chain. The device may cause to send a first frame of one or more frames to a responder device using the first analog direction. The device may cause to send a second frame of the one or more frames to the responder device using the second analog direction. The device may identify one or more response frames received from the responder device, wherein at least one of the one or more response frames comprises an indication of an identified transmit direction.

    Abstract: For example, an apparatus may include logic and circuitry configured to cause a first wireless station to perform a Transmit Sector Sweep (TXSS) protocol with a second wireless station over a directional frequency band using a plurality of antennas of the first wireless station, an antenna of the plurality of antennas of the first wireless station comprising a plurality of sectors; to perform a Receive Sector Sweep (RXSS) protocol with the second wireless station over the directional frequency band using the plurality of antennas of the first wireless station; and, based on the TXSS and RXSS protocols, to configure the plurality of antennas of the first wireless station to communicate a Single-User (SU) Multiple-Input-Multiple-Output (MIMO) transmission with the second wireless station.

    Abstract: This disclosure describes methods, apparatus, and systems to increase the transmission data rate in wireless networks, for example, by using one or more Multiple Input Multiple Output (MIMO) and/or channel bonding techniques. In one embodiment, the disclosure describes the use of Golay Sequence Sets (GSS) to define guard intervals (GIs) for single carrier (SC) single channel bonding and multiple input multiple output (MIMO) transmission. In various embodiments, the disclosure describes the design of guard interval sequence for 3 types of guard intervals having lengths that can be classified as short, medium, and long. In another embodiment, the disclosure defines the guard interval for single channel transmission channel bonding and for MIMO transmission.

    Abstract: Some demonstrative embodiments include apparatus, system and method of communicating a Multiple-Input-Multiple-Output (MIMO) transmission with Golay Sequence Set (GSS). For example, an apparatus may include logic and circuitry configured to cause a wireless station to generate a Golay Sequence Set (GSS) including a plurality of complementary Golay sequence pairs based on a plurality of weight vectors, the plurality of weight vectors including one or more weight vectors corresponding to one or more respective stream numbers, which are equal to or greater than 9; and transmit a Multiple-Input-Multiple-Output (MIMO) transmission over a plurality of spatial streams, the MIMO transmission including at least one field transmitted over a spatial stream having a stream number equal to or greater than 9, the field is based on a complementary Golay sequence pair of the plurality of complementary Golay sequence pairs, which is based on a weight vector corresponding to the stream number.
