1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a non-access point (non-AP) station (STA) from an access point (AP), a trigger frame including a Common Info field and a User Info field,
wherein the User Info field includes information related to allocation of a multiple-resource unit (RU) (MRU) including a first RU and a second RU, wherein the first RU and the second RU are allocated to the non-AP STA, wherein the first RU is allocated contiguous to the second RU in frequency,
wherein whether the MRU is allocated to the non-AP STA is determined based on the information; and
in response to the trigger frame, transmitting, by the non-AP STA to the AP, a Physical Protocol Data Unit (PPDU) configured based on the trigger frame, wherein the PPDU includes a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field being contiguous to the L-SIG field, and a first signal field being contiguous to the RL-SIG field,
wherein the RL-SIG field carries 24-bit information related to length information,
wherein four extra subcarriers are inserted at indexes of {−28, −27, 27, 28} in the RL-SIG field, and values of the four extra subcarriers are {−1,−1,−1, 1}, respectively,
wherein each symbol of the first signal field carries 26-bit information, and the first signal field comprises version independent fields including first bits related to transmission opportunity (TXOP) and second bits related to a Basic Service Set (BSS) Color Identifier (ID).
