Detailed Description

Headers for Trigger frames.

Introspection did not find any typical Config paths.

802.11ax amendment defines eight types of Trigger frames (see Section 9.3.1.23 of D3.0):

Basic
Beamforming Report Poll (BFRP)
Multi-User Block Ack Request (MU-BAR)
Multi-User Request To Send (MU-RTS)
Buffer Status Report Poll (BSRP)
Groupcast with Retries (GCR) MU-BAR
Bandwidth Query Report Poll (BQRP)
NDP Feedback Report Poll (NFRP) For now only the Basic, MU-BAR, MU-RTS, BSRP and BQRP variants are supported. Basic Trigger is also the default variant.

The Padding field is optional, given that other techniques (post-EOF A-MPDU padding, aggregating other MPDUs in the A-MPDU) are available to satisfy the minimum time requirement. Currently, however, a Padding field of the minimum length (2 octets) is appended to every Trigger frame that is transmitted. In such a way, deserialization stops when a User Info field with the AID12 subfield set to 4095 (which indicates the start of a Padding field) is encountered.

No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 40 bytes (on a 64-bit architecture).

◆ CtrlTriggerHeader() [2/2]

ns3::CtrlTriggerHeader::CtrlTriggerHeader	(	TriggerFrameType	type,
		const WifiTxVector &	txVector
	)

Constructor.

Construct a Trigger Frame of the given type from the values stored in the given TX vector. In particular:

the UL Bandwidth, UL Length and GI And LTF Type subfields of the Common Info field are set based on the values stored in the TX vector;
as many User Info fields as the number of entries in the HeMuUserInfoMap of the TX vector are added to the Trigger Frame. The AID12, RU Allocation, UL MCS and SS Allocation subfields of each User Info field are set based on the values stored in the corresponding entry of the HeMuUserInfoMap.

Parameters

type	the Trigger frame type
txVector	the TX vector used to build this Trigger Frame

Make sure that the type of the given User Info field matches the type of this Trigger Frame.

Parameters

userInfo the User Info field to append to this Trigger Frame

Returns: a non-const reference to the newly added User Info field

◆ Deserialize()

uint32_t ns3::CtrlTriggerHeader::Deserialize ( Buffer::Iterator start )

virtual

Parameters

start an iterator which points to where the header should read from.

Returns: the number of bytes read.

This method is used by Packet::RemoveHeader to re-create a header from the byte buffer of a packet. The data read is expected to match bit-for-bit the representation of this header in real networks.

Note that data is not actually removed from the buffer to which the iterator points. Both Packet::RemoveHeader() and Packet::PeekHeader() call Deserialize(), but only the RemoveHeader() has additional statements to remove the header bytes from the underlying buffer and associated metadata.

Implements ns3::Header.

◆ Print()

void ns3::CtrlTriggerHeader::Print ( std::ostream & os ) const

virtual

Parameters

os output stream This method is used by Packet::Print to print the content of a header as ascii data to a c++ output stream. Although the header is free to format its output as it wishes, it is recommended to follow a few rules to integrate with the packet pretty printer: start with flags, small field values located between a pair of parens. Values should be separated by whitespace. Follow the parens with the important fields, separated by whitespace. i.e.: (field1 val1 field2 val2 field3 val3) field4 val4 field5 val5

◆ Serialize()

void ns3::CtrlTriggerHeader::Serialize ( Buffer::Iterator start ) const

virtual

Parameters

start an iterator which points to where the header should be written.

This method is used by Packet::AddHeader to store a header into the byte buffer of a packet. The data written is expected to match bit-for-bit the representation of this header in a real network.
