Measurement based QoS adaptation

A device for controlling a bit rate of a terminal included in a group of terminals relative to other terminals in the group, the device comprising a processor coupled to a memory, the processor configured to:

• acquire a predetermined Quality of Service (QoS) parameter for the terminal, the acquired predetermined QoS parameter stipulating a target bitrate for the terminal relative to other terminals in the group;
• acquire at least one measure of a channel condition of the terminal and at least one capacity measure of the terminal, wherein the at least one measure of the channel condition of the terminal is a Channel Quality Indicator (CQI) for the terminal and the at least one capacity measure of the terminal is a supported Uu bit rate for the terminal;
• and
• control the bit rate of the terminal using a reference weighting factor created by a combination of the acquired predetermined QoS parameter, the acquired at least one measure of the channel condition of the terminal, and the acquired at least one capacity measure of the terminal;
• wherein the created reference weighting factor increases as the channel condition improves and the created reference weighting factor decreases as the channel condition deteriorates.
