Abstract: This disclosure describes enhanced directional multi gigabit (EDMG) physical layer convergence procedure (PLCP) protocol data unit (PPDU) frames and frame formats for wireless networks. The frame can include a legacy portion and a non-legacy portion. The legacy portion of the frame can be transmitted using a legacy sample (or chip) rate. The non-legacy portion of the frame can be transmitted using a second, different sample (or chip) rate. A transition interval field may be defined between the legacy and the non-legacy portions of the frame, the transition interval field having a predetermined time duration. In one embodiment, the transition interval field can be defined and/or used in connection with one or more standards (for example, a IEEE 802.11ay standard). The various embodiments disclosed herein can be used to facilitate hardware implementation, increase vendor-agnostic compatibility, and allow for accurate, vendor agnostic time-of-flight (ToF) measurements.

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.

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: 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.
