Unsupported Modulation Reception Test This test creates a mixed network, in which an HE STA and a VHT STA are associated to an HE AP and send uplink traffic.
In the simulated deployment the VHT STA's backoff will expire while the HE STA is sending a packet, and the VHT STA will access the channel anyway. This happens because the HE STA is using an HeMcs that the VHT STA is not able to demodulate: the VHT STA will correctly stop listening to the HE packet, but it will not update its InterferenceHelper with the HE packet. Later on, this leads to the STA wrongly assuming the medium is available when its back-off expires in the middle of the HE packet. We detect that this is happening by looking at the reason why the AP is failing to decode the preamble from the VHT STA's transmission: if the reason is that it's in RX already, the test fails. The test is based on wifi-txop-test.cc.
