1. A wireless communication terminal, the terminal comprising:

  • a processor; and

    a communication unit, wherein the processor is configured to;

    receive a trigger frame indicating an uplink multi-user transmission, and transmit a trigger-based PHY protocol data unit (PPDU) in response to the received trigger frame, wherein the trigger-based PPDU comprises a spatial reuse parameter for spatial reuse operation of an overlapping basic service set (OBSS) terminal;

    wherein a total bandwidth on which transmission of trigger-based PPDU(s) in response to the trigger frame is performed is indicated by a bandwidth field of a high efficiency signal field A (HE-SIG-A) of the trigger based-PPDU, and wherein when the total bandwidth consists of a first frequency band and a second frequency band which are non-contiguous with each other, a spatial reuse parameter for the first frequency band and a spatial reuse parameter for the second frequency band are set to the same value.
