void ns3::MacLow::CreateBlockAckAgreement	(	const MgtAddBaResponseHeader *	respHdr,
		Mac48Address	originator,
		uint16_t	startingSeq
	)

Parameters

respHdr	Add block ack response from originator (action frame).
originator	Address of peer station involved in block ack mechanism.
startingSeq	Sequence number of the first MPDU of all packets for which block ack was negotiated.

This function is typically invoked only by ns3::RegularWifiMac when the STA (which may be non-AP in ESS, or in an IBSS) has received an ADDBA Request frame and is transmitting an ADDBA Response frame. At this point MacLow must allocate buffers to collect all correctly received packets belonging to the category for which Block Ack was negotiated.

Parameters

originator	Address of peer participating in Block Ack mechanism.
tid	TID for which Block Ack was created.

Checks if exists an established block ack agreement with originator for tid tid. If the agreement exists, tears down it. This function is typically invoked when a DELBA frame is received from originator.

void ns3::MacLow::DoDispose ( void )

privatevirtual

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

Subclasses are expected to implement their real destruction code in an overriden 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.

Reimplemented from ns3::Object.

A STA that used information from an RTS frame as the most recent basis to update its NAV setting is permitted to reset its NAV if no PHY-RXSTART.indication is detected from the PHY during a period with a duration of (2 * aSIFSTime) + (CTS_Time) + (2 * aSlotTime) starting at the PHY-RXEND.indication corresponding to the detection of the RTS frame. The “CTS_Time” shall be calculated using the length of the CTS frame and the data rate at which the RTS frame used for the most recent NAV update was received.

void ns3::MacLow::RxCompleteBufferedPacketsUntilFirstLost	(	Mac48Address	originator,

	)

private

Parameters

originator	Address of peer participating in Block Ack mechanism.
tid	TID for which Block Ack was created.

This method is typically invoked when a MPDU with ack policy subfield set to Normal Ack is received and a block ack agreement for that packet exists. This happens when the originator of block ack has only few MPDUs to send. All completed MSDUs starting with starting sequence number of block ack agreement are forward up to WifiMac until there is an incomplete or missing MSDU. See section 9.10.4 in IEEE802.11 standard for more details.
