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.

Methods, system and user equipment of a wireless communication network for determining transmission conditions for a real-time media flow

Embodiments herein relate to a method, performed by a network node, for handling of specific power reduction for a User Equipment (UE). The network node receives a message from the UE comprising an identification of a specific type of the UE. The network node obtains a reduced power applied by the UE corresponding to the received identification. The network node selects an allocation for transmissions from the UE, based on the reduced power applied by the UE. Embodiments herein further relate to a network node for performing the method for handling of specific power reduction for a UE.

Network node and method for UE specific power handling

Disclosed is a method performed by a system of a wireless communication network for determining transmission conditions for a real-time media flow to be transmitted wirelessly to a first User Equipment, UE, residing in a first cell served by a first base station of the network. The method comprises obtaining radio network statistics of the first cell, the radio network statistics comprising radio network data for individual of a plurality of UEs in the first cell, UE throughput for individual of the plurality of UEs, and UE packet loss or packet delay for individual of the plurality of UEs, and obtaining, at a second time point occurring later in time than the obtaining of the radio network statistics, radio network data for the first UE. The method further comprises determining a predicted first UE throughput and a predicted first UE packet loss or packet delay based on the obtained radio network statistics of the first cell and on the obtained radio network data for the first UE, and triggering sending of information of the predicted first UE throughput and of the predicted first UE packet loss or excessive packet delay to a sender of the real-time media flow to the first UE. A Forward Error Correction, FEC, optimization module takes the predicted UE packet loss rate, the predicted UE throughput, and adapts the amount of FEC redundancy packets according to the throughput and packet loss rate. Further, the adapted amount of FEC redundancy packets are then used by the sender of the video when transmitting the video.

A method and node for uplink scheduling of a plurality of wireless devices in a communications network is provided. The method includes estimating, for each of a plurality of wireless devices, a buffer size corresponding to each of at least one radio bearer group (RBG), each of the at least one RBG being used by the wireless device to carry traffic via multiple bearers. The method further includes determining an uplink resource maximum allotment for each wireless device based, at least in part, on the estimated buffer sizes and a priority weight of each RBG used by the plurality of wireless devices. The priority weight of each RBG is based at least in part on quality of service (QoS) requirements of bearers carried by the RBG.

Decreasing free-riding data traffic in uplink scheduling

A method in a base station for selecting a transport format is provided. The base station allocates resources to a User Equipment, UE. When a first criterion is fulfilled for the allocated resources, the base station estimates Signal-to-Interference-plus-Noise Ratio, SINR, by using a first gain offset. The first gain offset relates to a resource allocation according to the first criterion. When a second criterion is fulfilled for the allocated resources, the base station estimates SINR by using a second gain offset. The second gain offset relates to a resource allocation according to the second criterion. The base station then selects a transport format for the allocated resources based on the estimated SINR.
