Abstract

A method performed by a user equipment (UE) wirelessly connected to a wireless communication network for facilitating transmission of a real-time media flow from a sender towards the UE is described. The method includes sending a request to the network, requesting a packet loss prediction and a throughput prediction for transmission of a real-time media flow from the network towards the UE. The method also includes receiving, from the network, information of a predicted UE throughput and a predicted UE packet loss predicted by the network in response to the sent request. In some embodiments, the method also includes sending the received information to a sender of the real-time media flow to the UE.
