Abstract: This disclosure describes methods, apparatus, and systems related to media access control (MAC) range extension. A device may cause to append a training field to each of one or more beacon frames. The device may cause to send the one or more beacon frames directionally using a sector sweep to one or more responder devices during a first interval. The device may determine an extended schedule element to be sent to the one or more responder devices, the extended schedule element including one or more directional antenna sectors to be used by the device during a second interval. The device may identify a first frame from a first responder device, during the second interval, wherein the first frame is received on a directional antenna sector of the one or more directional antenna sectors corresponding to an operating sector of the first responder device.

Abstract: Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a Single Carrier (SC) Space Time Block Coding (STBC) transmission. For example, a station may generate a plurality of space-time streams including at least a first space-time stream and a second space-time stream, the first space-time stream including, in a first interval, a first data sequence followed by a first Guard Interval (GI) sequence, the second space-time stream including, in the first interval, a second data sequence followed by a second GI sequence, the first space time stream comprising, in a second interval subsequent to the first interval, a sign-inverted and time-inverted complex conjugate of the second data sequence followed by the first GI sequence, the second stream including, in the second interval, a time-inverted complex conjugate of the first data sequence followed by the second GI sequence; and transmit a SC STBC transmission based on the plurality of space-time streams.

Abstract: Apparatus, computer readable media, and methods for enhanced beamforming training in a wireless local area network are disclosed. An apparatus of a access point or station is disclosed. The apparatus including processing circuitry where the processing circuitry is configured to encode an EBRP packet comprising a first portion comprising an indication of a first number of transmit antenna training settings (N-TX), and an indication of a second number of receive training subfields per N-TX settings (N-RX), and a second portion comprising a third number of training subfields. The third number may be less than or equal to N-TX times N-RX. The processing circuitry may be configured to cause the first portion of the EBRP packet to be transmitted and cause the second portion to be transmitted, where two or more of the third number of training subfields are to be transmitted simultaneously using different antennas and orthogonal sequences.
