1. A wireless communication method by a first apparatus, the wireless communication method comprising:
receiving a first Physical Layer Protocol Data Unit (PPDU) from a second apparatus;
extracting a first field from a first signal field included in the first PPDU;
extracting a common field from a second signal field included in the first PPDU; and
identifying a number of symbols in the second signal field based on a value of the first field,
wherein the identifying the number of symbols in the second signal field comprises identifying that the number of symbols in the second signal field is equal to or greater than a first number when the first field has a first value, and
wherein identifying that the number of symbols in the second signal field is equal to or greater than the first number comprises:
identifying a number of user fields in the second signal field based on a value of at least one Resource Unit (RU) allocation subfield included in the common field; and
calculating the number of symbols in the second signal field based on the number of user fields.
