2. The wireless communication system according to Claim 1, wherein
the AP disables the AP’s own OBSS_PD-based SR and transmits, to the
STA, signaling that instructs the STA to disable the OBSS_PD-based SR, and the STA disables the STA’s own OBSS_PD-based SR.
3. The wireless communication system according to Claim 2, wherein
the AP transmits, to the STA, the signaling not to update an Intra-BSS
NAV and a Basic NAV, and
the STA does not update the STA’s own Intra-BSS NAV and the own Basic NAV.
4. The wireless communication system according to Claim 1, wherein
the STA enables or disables the STA’s own OBSS_PD-based SR based on
an Inter-BSS frame received from the OBSS and transmits, to the AP, first signaling that notifies the AP of a setting of the STA’s own OBSS_PD-based SR,
the AP makes a setting of the AP’s own OBSS_PD-based SR similar to the setting notified by the first signaling and transmits, to an STA other than the STA belonging to the BSS, second signaling that instructs the STA to make a setting of the OBSS_PD-based SR similar to the setting notified by the first signaling, and
the STA that has received the second signaling makes a setting of the STA’s own OBSS_PD-based SR similar to the setting instructed by the second signaling.
5. The wireless communication system according to Claim 4, wherein
the STA enables or disables the STA’s own Intra-BSS NAV and the STA’s own Basic NAV based on the Inter-BSS frame received from the OBSS and

transmits, to the AP, the first signaling that notifies the AP of a setting of the STA’s own Intra-BSS NAV and the STA’s own Basic NAV,
the AP transmits, to an STA other than the STA belonging to the BSS, the second signaling that instructs the STA to make a setting of the Intra-BSS NAV and the Basic NAV similar to the setting notified by the first signaling, and
the STA that has received the second signaling makes a setting of the STA’s own Intra-BSS NAV and the STA’s own Basic NAV similar to the setting instructed by the second signaling.
6. The wireless communication system according to Claim 4 or 5, wherein
the STA disables the STA’s own OBSS_PD-based SR based on a first
beacon frame received from the OBSS and transmits, to the AP, a management frame that notifies the AP of the setting of the STA’s own OBSS_PD-based SR,
the AP disables the AP’s own OBSS_PD-based SR based on the management frame and transmits, to an STA other than the STA belonging to the BSS, a second beacon frame that instructs the STA to disable the OBSS_PD-based SR, and
the STA that has received the second beacon frame disables the STA’s own OBSS_PD-based SR based on the second beacon frame.
7. The wireless communication system according to any one of Claims 4 to
6, wherein
the STA enables the STA’s own OBSS_PD-based SR based on an Inter BSS PPDU received from the OBSS and transmits, to the AP, a management frame that notifies the AP of the setting of the own OBSS_PD-based SR,
the AP enables the AP’s own OBSS_PD-based SR based on the management frame and transmits, to an STA other than the STA belonging to the BSS, a beacon frame that instructs the STA to turn on the OBSS_PD-based SR, and
the STA that has received the beacon frame enables the STA’s own OBSS_PD-based SR based on the beacon frame.
8. An access point (AP) in a wireless communication system, the wireless
communication system comprising the AP and a terminal (STA) that belong to a
Basic Service Set (BSS),

the AP comprising:
a memory configured to store instructions; and
at least one processor configured to process the instructions, wherein
the processor adaptively disables Overlapping BSS (OBSS)_Power Detect (PD)-based Spatial Reuse (SR) that performs adjustment so as to avoid interference between the BSS and the OBSS.
9. The AP according to Claim 8, wherein the processor disables the AP’s
own OBSS_PD-based SR and transmits, to the STA, signaling that instructs the
STA to disable the OBSS_PD-based SR.
10. The AP according to Claim 9, wherein the processor transmits, to the STA, the signaling not to update an Intra-BSS NAV and a Basic NAV.
11. A terminal (STA) in a wireless communication system, the wireless communication system comprising an access point (AP) and the STA that belong to a Basic Service Set (BSS),
the STA comprising:
a memory configured to store instructions; and
at least one processor configured to process the instructions, wherein
the processor adaptively disables Overlapping BSS (OBSS)_Power Detect (PD)-based Spatial Reuse (SR) that performs adjustment so as to avoid interference between the BSS and the OBSS.
12. The STA according to Claim 11, wherein the processor disables the STA’s own OBSS_PD-based SR upon receiving, from the AP, signaling that instructs the STA to disable the OBSS_PD-based SR.
13. The STA according to Claim 12, wherein the processor does not update the STA’s own Intra-BSS NAV and the STA’s own Basic NAV upon receiving the signaling from the AP.
14. A communication method performed by an access point (AP) in a wireless communication system, the wireless communication system comprising

the AP and a terminal (STA) that belong to a Basic Service Set (BSS),
the communication method comprising adaptively disabling Overlapping BSS (OBSS)_Power Detect (PD)-based Spatial Reuse (SR) that performs adjustment so as to avoid interference between the BSS and the OBSS.
