Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

WifiTxVector ns3::HeFrameExchangeManager::GetHeTbTxVector ( CtrlTriggerHeader  trigger,

Return a TXVECTOR for the UL frame that the station will send in response to the given Trigger frame, configured with the BSS color and transmit power level to use for the consequent HE TB PPDU.

Note that this method should only be called by non-AP stations only.

Parameters
triggerthe received Trigger frame
triggerSenderthe MAC address of the AP sending the Trigger frame
Returns
TXVECTOR for the HE TB PPDU frame

Get the transmit power to use for an HE TB PPDU considering:

  • the transmit power used by the AP to send the Trigger Frame (TF), obtained from the AP TX Power subfield of the Common Info field of the TF.
  • the target uplink RSSI expected by the AP for the triggered HE TB PPDU, obtained from the UL Target RSSI subfield of the User Info field of the TF.
  • the RSSI of the PPDU containing the TF, typically logged by the WifiRemoteStationManager upon reception of the TF from the AP.

It is assumed that path loss is symmetric (i.e. uplink path loss is equivalent to the measured downlink path loss);
