3968 * @brief Unsupported Modulation Reception Test
3969 * This test creates a mixed network, in which an HE STA and a VHT
3970 * STA are associated to an HE AP and send uplink traffic. In the
3971 * simulated deployment the VHT STA's backoff will expire while the
3972 * HE STA is sending a packet, and the VHT STA will access the
3973 * channel anyway. This happens because the HE STA is using an HeMcs
3974 * that the VHT STA is not able to demodulate: the VHT STA will
3975 * correctly stop listening to the HE packet, but it will not update
3976 * its InterferenceHelper with the HE packet. Later on, this leads to
3977 * the STA wrongly assuming the medium is available when its back-off
3978 * expires in the middle of the HE packet. We detect that this is
3979 * happening by looking at the reason why the AP is failing to decode
3980 * the preamble from the VHT STA's transmission: if the reason is
3981 * that it's in RX already, the test fails. The test is based on
3982 * wifi-txop-test.cc.
