Extensive simulation has been done (see, e.g., Ref 15, Sony’s simulation) • 3GPP LAA also adopted an ED threshold adaptation (lower transmit power higher ED threshold) in the presence of other technologies 72dBm (20MHz ) Tmax X Thresh _ max max min T T ( P P ) A H TX max where PH 23dBm and PTX is TX power • 11ax should adopt similar adaptation rules for fair co-existence with 3GPP LAA and among .11 networks. .
