◆ CalculateTxDurationUsingList()

Time TxDurationTest::CalculateTxDurationUsingList	(	std::list< uint32_t >	sizes,
		std::list< uint16_t >	staIds,
		WifiTxVector	txVector,
		WifiPhyBand	band
	)

staticprivate

Calculate the overall Tx duration returned by WifiPhy for list of sizes.

A map of WifiPsdu indexed by STA-ID is built using the provided lists and handed over to the corresponding SU/MU WifiPhy Tx duration computing method. Note that provided lists should be of same size.

Parameters

sizes	the list of PSDU sizes for each station in octets
staIds	the list of STA-IDs of each station
txVector	the TXVECTOR used for the transmission of the PPDU
band	the selected wifi PHY band

Returns: the overall Tx duration for the list of sizes (SU or MU PPDU)

	)

staticprivate

Check if the overall Tx duration returned by WifiPhy for a MU PPDU corresponds to a known value.

Parameters

sizes	the list of PSDU sizes for each station in octets
userInfos	the list of HE MU specific user transmission parameters
channelWidth	the channel width used for the transmission (in MHz)
guardInterval	the guard interval duration used for the transmission (in nanoseconds)
preamble	the WifiPreamble used for the transmission
knownDuration	the known duration value of the transmission

Returns: true if values correspond, false otherwise
