1. An integrated circuit for a first wireless station that belongs to a communication cell, the integrated circuit comprising at least one input, which, in operation, inputs an electronic signal, and controller circuitry, which, in operation, controls:
receiving, at the first wireless station, a trigger frame transmitted from an access point that belongs to an interference cell, the trigger frame soliciting uplink response signals from a plurality of terminal stations belonging to the interference cell and including a target RSSI (received signal strength indicator) that is a target reception power value of the uplink response signals at the access point;
determining, at the first wireless station, based on i) a class of the first wireless station indicating RSSI measurement precision, ii) a parameter for an allowable interference level, and iii) a reception power value of the trigger frame received at the first wireless station, whether the first wireless station is allowed to transmit a signal to a second wireless station that belongs to the communication cell, wherein the parameter is set based on an access point transmit power of the access point and based on the target RSSI; and
transmitting, from the first wireless station, the signal while the plurality of terminal stations transmit the uplink response signals by MU (Multi User) multiplexing.
