Abstract:
An communication apparatus of the present disclosure comprises a receiver that receives a Trigger frame for allocating resource units (RUs) for random access and another frame including Random Access parameter element that comprises a first field indicating an OFDMA contention window (OCW) minimum value (OCWmin) and a second field indicating an OCW maximum value (OCWmax); and control circuitry that controls Uplink OFDMA-based Random Access (UORA) procedure using the OCWmin and the OCWmax.
