◆ UpdateTxVectorForUlMu()

void ns3::HePpdu::UpdateTxVectorForUlMu ( const std::optional< WifiTxVector > & trigVector ) const

Update the TXVECTOR for HE TB PPDUs, since the information to decode HE TB PPDUs is not available from the PHY headers but it requires information from the TRIGVECTOR of the AP expecting these HE TB PPDUs.

Parameters

trigVector the TRIGVECTOR or std::nullopt if no TRIGVECTOR is available at the caller
