Wireless station and communication method for determining transmission to another wireless station in a cell in view of an interference cell

An integrated circuit for a first wireless station that belongs to a Basic Service Set (BSS), the integrated circuit comprising,

• at least one input, and
• control circuitry, which, in operation, controls:
• receiving, by the at least one input, a trigger frame transmitted from an Access Point (AP) that belongs to an overlapping BSS (OBSS), the trigger frame soliciting uplink multiuser signals from a plurality of wireless stations that belong to the OBSS;
• and
• transmitting a signal to a second wireless station that belongs to the BSS in spatial reuse operation while the uplink multiuser signals are being transmitted,
• wherein the spatial reuse operation is restricted based on a class of the first wireless station, the class indicating Received Signal Strength Indicator (RSSI) measurement precision.
