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) including a plurality of spatial reuse fields and a bandwidth field,
wherein the bandwidth field indicates a bandwidth related to transmission and reception of the trigger-based PPDU, and
wherein applied frequency bands to which the plurality of spatial reuse fields are used, and spatial reuse parameters of the plurality of spatial reuse fields vary according to a configuration and size of the bandwidth indicated by the bandwidth field, and
wherein a spatial reuse parameter for a first 80 MHz of the bandwidth is set to the same value as a spatial reuse parameter for a second 80 MHz of the bandwidth when the bandwidth indicates 80+80 MHz.
