1. A wireless communication method performed by a first apparatus, the wireless communication method comprising:
generating a first signal field having a fixed length;
generating a second signal field having a variable length; and
transmitting a physical layer protocol data unit (PPDU) including the first signal field and the second signal field to a second apparatus,
wherein said generating the second signal field comprises:
generating a bitstream;
generating an encoded block by encoding the bitstream;
generating an encoded block sequence by repeating the encoded block;
generating a modulated block by modulating the encoded block sequence; and
generating the second signal field to include one or more orthogonal frequency-division multiplexing (OFDM) symbols from the modulated block,
wherein the first signal field includes version-independent fields and version-dependent fields, and
wherein the second signal field includes a common field and a user specific field.
