1. A method comprising:
receiving an Association Response frame including a subfield related to whether a first link and a second link are a simultaneous transmit and receive (STR) link pair or a non-STR link pair;
receiving, by a first station (STA) related to the first link, a Physical Layer Protocol Data Unit (PPDU) including a legacy signal (L-SIG) field, a repeated L-SIG (RL-SIG) field being contiguous to the L-SIG field, and a first signal (SIG) field being contiguous to the RL-SIG field,
wherein the L-SIG field includes a length field, and a value of the length field is set to satisfy a condition that a remainder is zero (0) when the value of the length field is divided by three (3), and
wherein the first SIG field includes first information related to a PPDU type, second information related to an identifier of a basic service set (BSS), third information indicating duration information related to a transmission opportunity (TXOP), fourth information related to whether the PPDU is sent in uplink (UL) or in downlink (DL), fifth information related to a bandwidth, and sixth information having a length of 3 bits and indicating a physical (PHY) version of the PPDU;
based on the subfield indicating the first link and the second link are the non-STR link pair and on receiving the PPDU through the first link, configuring a state of a second STA related to the second link to a doze state during a duration of the PPDU;
transmitting, through by the first STA, an acknowledgment (ACK) frame in response to the PPDU; and
configuring the state of the second STA to an awake state during a duration of the ACK frame.
