Apparatus for transmitting and receiving data to provide high-speed data communication and method thereof

An apparatus in a wireless communication system, the apparatus comprising:

• a receiver configured to receive a frame, the frame comprising:
• a short preamble,
• a first and a second long preambles positioned subsequent to the short preamble,
• a first bit stream positioned between the first long preamble and the second long preamble, wherein the first bit stream comprising at least one bit, and
• a data field positioned subsequent to the second long preamble;
• and
• a circuitry configured to determine, based on information in the first bit stream, whether or not the frame is transmitted using space time block coding.

A wireless communication method comprising:

An apparatus in a wireless communication system, the apparatus comprising:

• a receiver configured to receive a frame, the frame comprising:
• a first portion,
• a second portion subsequent to the first portion,
• a third portion subsequent to the second portion,
• a fourth portion subsequent to the third portion, and
• a fifth portion subsequent to the fourth portion,
• wherein:
• the first portion comprises a short preamble,
• the second portion comprises a first long preamble,
• the third portion comprises information about space time block coding,
• the fourth portion comprises a second long preamble, and
• the fifth portion comprises a data field;
• and
• a circuitry configured to determine, based on information in the third portion, whether or not the frame is transmitted using space time block coding.
