Abstract
A wireless communication system according to the present disclosure includes an access point (AP) belonging to a certain BSS and a terminal (STA) belonging to the AP. The STA updates an NAV used for virtual carrier sense according to whether the AP and the STA are permitted to use OBSS_PD-based SR.
Claims2
A terminal (STA) in a Basic Service Set (BSS) comprising an access point (AP) and the STA, the STA comprising:
- a memory configured to store instructions;
- and
- at least one processor configured to process the instructions to:
- receive an inter-BSS frame and, based on a setting which is set to on, wherein the setting is associated with Overlapping BSS (OBSS) Power Detect (PD)-based Spatial Reuse (SR), not update a Basic Network Allocation Vector (NAV) used for virtual carrier sense;
- and
- receive an intra-BSS frame and, based on the intra-BSS frame, update an intra-BSS NAV used for virtual carrier sense.
3 more elements
A communication method performed by a terminal (STA) in a Basic Service Set (BSS) comprising an access point (AP) and the STA, the communication method comprising:
- receiving an inter-BSS frame and, based on a setting which is set to on, wherein the setting is associated with Overlapping BSS (OBSS) Power Detect (PD-based Spatial Reuse (SR), not updating a Basic Network Allocation Vector (NAV) used for virtual carrier sense;
- and
- receiving an intra-BSS frame and, based on the intra-BSS frame, updating an intra-BSS NAV used for virtual carrier sense.
