摘要

The method includes generating a preamble of the first data unit according to the first format. Generating the preamble of the first data unit according to the first format includes generating a first preamble portion of the first data unit and generating a second preamble portion of the first data unit. The first preamble portion of the first data unit includes information indicating to the receiving device that the first data unit is a single-user data unit, and the second preamble portion of the first data unit represents the first preamble portion of the first data unit. Follows. The method also includes applying the beamforming steering matrix to the second preamble portion of the first data unit but not to the first preamble portion of the first data unit.
