WIRELESS CHANNEL CALIBRATION |
摘要 |
This document describes, among other things, a method that includes transmitting a calibration initiation frame from a first wireless communication device to a second wireless communication device that comprises a single space-time stream transmitter via a wireless communication medium. The method also includes receiving at the first wireless communication device an acknowledgement frame sent from the second wireless communication device after the second wireless communication device receives the calibration initiation frame. The method further includes transmitting a null data packet (NDP) frame from the first wireless communication device to the second wireless communication device after receiving the acknowledgement frame. In some implementations, the method also includes performing beamforming calibration of a wireless communication channel between the first wireless communication device and the second wireless communication device based on the acknowledgement frame. |
