Fields

Name	Type	Description
byteLength
category		representing Block Ack
blockAckAction	int	representing ADDBA request
dialogToken	int	nonzero, arbitrary
aMsduSupported	bool	Block Ack Parameter Set field
blockAckPolicy	bool	The Block Ack Policy subfield is set to 1 for immediate Block Ack and 0 for delayed Block Ack.
tid	int	The TID subfield contains the value of the TC or TS for which the BlockAck is being requested.
bufferSize	int	The Buffer Size subfield indicates the number of buffers available for this particular TID
blockAckTimeoutValue	simtime_t	Block Ack Timeout Value field The Block Ack Timeout Value field contains the duration, in TUs, after which the Block Ack setup is terminated, if there are no frame exchanges (see 10.5.4) within this duration using this Block Ack agreement. A value of 0 disables the timeout.
_fragmentNumber	int	Block Ack Starting Sequence Control The Starting Sequence Number subfield of the Block Ack Starting Sequence Control subfield contains the sequence number of the first MSDU for which this Basic BlockAckReq frame is sent. The Fragment Number subfield is set to 0.
startingSequenceNumber	int	the sequence number of the first MSDU
