TXOP (transmission opportunity)
TXOP is defined in IEEE 802.11e as the interval of time when a particular QSTA (QoS STA) has the right to initiate transmissions. TXOP used in both EDCA and HCCA modes of operation, it is a bounded time interval in which Stations supporting Quality of Service are permitted to transfer a series of frames. A TXOP is defined by a start time and a maximum duration. There are two modes of EDCA TXOP defined, the initiation of the EDCA TXOP and the multiple frame transmission within an EDCA TXOP.
