Member Function Documentation

◆ NotifyCcaBusyStart()

void TestPhyListener::NotifyCcaBusyStart	(	Time	duration,
		WifiChannelListType	channelType,
		const std::vector< Time > &	per20MhzDurations
	)

inlineoverridevirtual

Parameters

duration	the expected busy duration.
channelType	the channel type for which the CCA busy state is reported.
per20MhzDurations	vector that indicates for how long each 20 MHz subchannel (corresponding to the index of the element in the vector) is busy and where a zero duration indicates that the subchannel is idle. The vector is non-empty if the PHY supports 802.11ax or later and if the operational channel width is larger than 20 MHz.

This method does not really report a real state change as opposed to the other methods in this class. It merely reports that, unless the medium is reported busy through NotifyTxStart or NotifyRxStart/End, it will be busy as defined by the currently selected CCA mode.

Typical client code which wants to have a clear picture of the CCA state will need to keep track of the time at which the last NotifyCcaBusyStart method is called and what duration it reported.

Here is the call graph for this function:

◆ NotifyOff()

void TestPhyListener::NotifyOff ( )

inlineoverridevirtual

Notify listeners that we went to switch off.

Implements ns3::WifiPhyListener.

Definition at line 320 of file spectrum-wifi-phy-test.cc.

◆ NotifyOn()

void TestPhyListener::NotifyOn ( )

inlineoverridevirtual

Notify listeners that we went to switch on.

Implements ns3::WifiPhyListener.

Definition at line 328 of file spectrum-wifi-phy-test.cc.

◆ NotifyRxEndError()

void TestPhyListener::NotifyRxEndError ( )

inlineoverridevirtual

We have received the last bit of a packet for which NotifyRxStart was invoked first and, the packet has not been successfully received.

Implements ns3::WifiPhyListener.

Definition at line 285 of file spectrum-wifi-phy-test.cc.

References m_notifyRxEndError, and NS_LOG_FUNCTION.

◆ NotifyRxEndOk()

void TestPhyListener::NotifyRxEndOk ( )

inlineoverridevirtual

We have received the last bit of a packet for which NotifyRxStart was invoked first and, the packet has been successfully received.

Implements ns3::WifiPhyListener.

Definition at line 279 of file spectrum-wifi-phy-test.cc.

References m_notifyRxEndOk, and NS_LOG_FUNCTION.

◆ NotifyRxStart()

void TestPhyListener::NotifyRxStart ( Time duration )

inlineoverridevirtual

Parameters

duration the expected duration of the packet reception.

We have received the first bit of a packet. We decided that we could synchronize on this packet. It does not mean we will be able to successfully receive completely the whole packet. It means that we will report a BUSY status until one of the following happens:

NotifyRxEndOk
NotifyRxEndError
NotifyTxStart

Implements ns3::WifiPhyListener.

Definition at line 273 of file spectrum-wifi-phy-test.cc.

References m_notifyRxStart, and NS_LOG_FUNCTION.

◆ NotifySleep()

void TestPhyListener::NotifySleep ( )

inlineoverridevirtual

Notify listeners that we went to sleep.

Implements ns3::WifiPhyListener.

Definition at line 316 of file spectrum-wifi-phy-test.cc.

◆ NotifySwitchingStart()

void TestPhyListener::NotifySwitchingStart ( Time duration )

inlineoverridevirtual

Parameters

duration the expected channel switching duration.

We do not send any event to notify the end of channel switching. Listeners should assume that the channel implicitly reverts to the idle or busy states.

Implements ns3::WifiPhyListener.

Definition at line 312 of file spectrum-wifi-phy-test.cc.

◆ NotifyTxStart()

void TestPhyListener::NotifyTxStart	(	Time	duration,
		double	txPowerDbm
	)

inlineoverridevirtual

Parameters

duration	the expected transmission duration.
txPowerDbm	the nominal TX power in dBm

We are about to send the first bit of the packet. We do not send any event to notify the end of transmission. Listeners should assume that the channel implicitly reverts to the idle state unless they have received a CCA busy report.
