    Abstract: A wireless communication method, by a first apparatus, includes 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, and identifying the number of symbols in the second signal field included in the first PPDU based on a value of the first field, wherein, when the first field has a first value, the identifying the number of symbols in the second signal field includes identifying that the number of symbols in the second signal field is equal to or greater than a first number.
