An example method for communicating over a wireless network having multiple sub-carrier frequencies can include assigning a first pilot signal to a first sub-carrier frequency for transmission with a first symbol, transmitting the first symbol from a first wireless device, receiving the first symbol at a second wireless device, determining channel time and phase offset using the first pilot signal, and estimating transmit beamforming channel state information using the first pilot signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmit beamforming sounding with traveling pilots","description":"This document discusses, among other things, apparatus and methods for transmit beamforming sounding.
