摘要： Various embodiments are generally directed to an apparatus, method and other techniques to perform beamforming training in a MIMO environment. Some embodiments may include communicating one or more beamforming refinement packets having training subfields with orthogonal structures such that devices may simultaneously perform beamforming training for each pair of phased array antennas. Embodiments may also include the beamforming refinement packets with channel estimation fields with orthogonal structures.

摘要： 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.

摘要： Disclosed herein are techniques to provide an indication of bandwidth to establish a TxOP using channel bonding. An information element may be generated to include an RTS frame or a CTS frame and an indication of bandwidth in a parity portion of the information element. The indication of bandwidth may be included by using 16 bits of the parity bits of parity bytes for a PHY header of the information element.

摘要： Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating a short Sector Sweep (SSW) packet. For example, an apparatus may include circuitry and logic configured to cause a first wireless station to generate a short Sector Sweep (SSW) packet including at least a packet type field, a countdown field, a short SSW feedback field, and a direction field, the packet type field including a value to indicate a Short SSW packet type, the countdown field including a counter value to indicate a number of remaining short SSW packet transmissions, the direction field to indicate whether transmission of the short SSW packet is from a beamforming initiator or a beamforming responder; and to transmit the short SSW packet to a second wireless station over a directional frequency band during beamforming training between the first and second wireless stations.

摘要： 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.
