1. A method in a wireless local area network system, the method comprising:
receiving, by a receiving STA from a transmitting STA, a first Physical Protocol Data Unit (PPDU), wherein at least one symbol of the first PPDU includes at least one extra tone;
determining, by the receiving STA, the format of the first PPDU as a repeated PPDU format based on the at least one extra tone; and
receiving, by the receiving STA from the transmitting STA, a second PPDU including the same data as the first PPDU based on the format of the first PPDU, wherein the first PPDU and the second PPDU are received through a 5.9 GHz band based on a frequency spacing of 156.25 kHz.
