Method and apparatus for controlling spatial reuse in wireless LAN system

An electronic device comprising:

• a communication circuit for wireless communication with at least one mobile device and at least one adjacent basic service set (BSS);
• and
• a processor operatively connected to the communication circuit,
• wherein the processor is configured to:
• select a mobile device to perform uplink transmission from among the at least one mobile device,
• determine an allowable interference level based on uplink transmission information to be used for uplink transmission by the mobile device connected to the electronic device,
• determine whether the interference level is allowed by the adjacent BSS,
• transmit a first trigger frame including a first configuration based on the interference level to the mobile device and the adjacent BSS through the communication circuit when the adjacent BSS allows the interference level,
• re-determine the uplink transmission information to be used for the uplink transmission by the mobile device in consideration of allowance of the interference level by the adjacent BSS when the adjacent BSS does not allow the interference level, and
• transmit a second trigger frame including a second configuration based on the interference level and the re-determined uplink transmission information to the mobile device and the adjacent BSS through the communication circuit.
