Detailed Description

Test TXOP rules.

A BSS consisting of an AP and 3 non-AP STAs is considered in this test. Both non-HT (802.11a) and HE devices are tested. Two TXOPs are simulated in this test:

In the first TXOP, the AP sends a QoS data frame to each of the three STAs. The Ack in response to the initial frame is corrupted, hence the AP terminates the TXOP and tries again when a new TXOP is gained. In the new TXOP, the initial frame sent to STA 1 is successfully received, while the second frame to STA 2 is corrupted. It is checked that the AP performs PIFS recovery or invokes backoff depending on the value of the PifsRecovery attribute. All QoS data frames transmitted have a length/duration that does not exceed the length/duration based RTS/CTS threshold, hence RTS/CTS is never used.
In the second TXOP, the AP sends a QoS data frame, in case of non-HT devices, or an A-MPDU consisting of 2 MPDUs, in case of HE devices, to each of the three STAs. All PSDUs transmitted have a length/duration that exceeds the length/duration based RTS/CTS threshold, hence RTS/CTS is used to protect every PSDU, unless the SingleRtsPerTxop attribute is set to true, in which case only the initial frame in the TXOP is protected by RTS/CTS.
