Detailed Description

Two BSSes, each with one AP and one non-AP STA, are configured to operate on different channels.

Specifically, the operating channel of BSS 1 is the secondary<X> channel of BSS 0, where X is half the width of the channel used by BSS 0. This test demonstrates that, if a transmission is ongoing on BSS 1, we can have a transmission on BSS 0 on its primary<X> channel.
