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: 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.

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: Described herein are architectures, platforms and methods for implementing a direct estimation of a transmitter's position based upon raw radio frequency (RF) signals that are received by a portable device. A mathematical operation such as a maximum-likelihood estimation (MLE) algorithm, which utilizes collected snapshots from the received raw RF signals as variables, is implemented to perform direct estimation.
