A method performed by a wireless device (110) for enabling reflective Quality-of-Service (QoS) to a bi-directional communications flow (130) in a wireless communications network (100) is provided. The wireless device (121) receives a downlink (DL) data packet of the bi-directional communications flow (130) indicating that reflective QoS is to be applied. The wireless device (121) then determines, based on the type of the bi-directional communications flow (130), that a first reflective QoS rule for filtering Uplink (UL) data packets of the bi-directional communications flow (130) cannot be derived based on control information comprised in the DL data packet. The wireless device (121) further obtains, based on the control information comprised in the DL data packet and the type of the bi-directional communications flow (130), a second reflective QoS rule for filtering UL data packets such that the control information comprised in an UL data packet is at least partly different from the control information comprised in the DL data packet. A wireless device (121) for enabling reflective Quality-of-Service (QoS) to a bi- directional communications flow (130) in a wireless communications network (100) is also provided.
