	)

overrideprotectedvirtual

Process SIG-B, perform amendment-specific actions, and provide an updated status of the reception.

Parameters

event	the event holding incoming PPDU's information
status	the status of the reception of the correctly received SIG-B after the configuration support check

Returns: the updated status of the reception of the SIG-B

void ns3::HePhy::SetEndOfHeSigACallback ( EndOfHeSigACallback callback )

Set a callback for a end of HE-SIG-A.

Parameters

callback the EndOfHeSigACallback to set

◆ SetTrigVector()

void ns3::HePhy::SetTrigVector	(	const WifiTxVector &	trigVector,

Set the TRIGVECTOR and the associated expiration time.

A TRIGVECTOR shall expire when the TX timer associated with the transmission of the Trigger Frame expires.

Parameters

trigVector	the TRIGVECTOR
validity	the amount of time (from now) until expiration of the TRIGVECTOR

◆ StartReceiveOfdmaPayload()

void ns3::HePhy::StartReceiveOfdmaPayload ( Ptr< Event > event )

protected

Start receiving the PSDU (i.e.

the first symbol of the PSDU has arrived) of an UL-OFDMA transmission. This function is called upon the RX event corresponding to the OFDMA part of the UL MU PPDU.

Parameters

event the event holding incoming OFDMA part of the PPDU's information

m_beginOfdmaPayloadRxEvents should still be running only for APs, since canceled in StartReceivePayload for STAs. This is because SpectrumWifiPhy does not have access to the device type and thus blindly schedules things, letting the parent WifiPhy class take into account device type.

◆ StartReceivePreamble()

void ns3::HePhy::StartReceivePreamble	(	Ptr< WifiPpdu >	ppdu,

overridevirtual

Start receiving the PHY preamble of a PPDU (i.e.

the first bit of the preamble has arrived).

This method triggers the start of the preamble detection period (

See also: StartPreambleDetectionPeriod) if the PHY can process the PPDU.

Parameters

ppdu	the arriving PPDU
rxPowersW	the receive power in W per band
rxDuration	the duration of the PPDU
