Suggestion wds, route, bridge for this wireless setup?

I have wireless setup :

reason for this case :

  • wds_ap must use 1 antenna/wireless cards
  • wds_station1 (right picture) cannot see wds_station2 (left picture)
  • only wds_ap can see wds_station1 either wds_station2 because high building blocking the sight

anyone with similiar setup?
any configuration you recommend, I’ll try!
thanks
