Yes, Qatar accept transit through airport. I recently went via qatar airline with no issues on RTD without PR.
Also if you’re using Qatar airline then it offers free hotel stay and meal vouchers within airport if your transit is more than 8 hours. Only thing is you have to pre-book accommodation on their website once you booked your airfare (only with Qatar airways). My stay was 17 hours and 20 hours on my way back ( you can transit upto 24 hours without any hassle).
