void ns3::PhyEntity::HandleRxPpduWithSameContent	(	Ptr< Event >	event,

	)

protectedvirtual

Handle reception of a PPDU that carries the same content of another PPDU.

This is typically called upon reception of preambles of HE MU PPDUs or reception of non-HT duplicate control frames that carries the exact same content sent from different STAs. If the delay between the PPDU and the first PPDU carrying the same content is small enough, PPDU can be decoded and its power is added constructively, and the TXVECTOR is updated accordingly. Otherwise, a new interference event is created and PPDU is dropped by the PHY.

Parameters

event	the event of the ongoing reception
ppdu	the newly received PPDU (UL MU or non-HT duplicate)
rxPower	the received power (W) per band of the newly received PPDU
