Abstract
Disclosed are techniques for communication. In an aspect, a communications devices communicates, from an upper communication layer (e.g., application layer) to a lower communication layer (e.g., transport layer), indication(s) to prioritize certain frames (e.g., recovery frames and/or feedback frames) over other frames (e.g., Inter frames) associated with the same QCI bearer for a video streaming session. The lower communication layer may place the prioritized frames ahead of the non-prioritized frames in a lower layer transmission buffer based on the indication. The communications device may transmit one or more packets carrying the first set of frames before one or more packets carrying the second set of frames based on the first set of frames being placed ahead of the second set of frames in the lower layer transmission buffer.
