  • Patent number: 11617187
    Abstract: Systems and methods are provided for synchronizing uplink (UL) and downlink (DL) traffic. In particular, frames associated with Quality of Service (QoS}-sensitive traffic flows to be transmitted in a first direction are prioritized commensurate with frames to be transmitted in a second direction, different/opposite to that of the first direction. For example, UL traffic flows can be prioritized based on DL traffic flows, where the traffic flows belong to the same application flow, and vice versa, where DL traffic flows can be prioritized based on UL traffic flows for the same application flow. In this way, end-to-end QoS can be achieved.
