Hey, Sacki!
As far as I know, the kick is in the first beat, snare in the third, and Hi Hats every 2 or 4 beats. BUT this is the most basic pattern you can do.
My advice is that you should build this basic pattern, then star experimenting with it. Adding more elements (a crash cymbal, or any other percussive sound), and try to make it blen with your melody (the bass, the wobbles, the leads, samples, anything you want!)
Also, you can speed up things, changing where you put the kicks and snares/claps, without changing the tempo of the song. You can even do some amen breaks (mostly used in Drum and Bass), with the average dubstep tempo (130-140BPM).
Hope I helped!
