Abstract
A method and an arrangement in a first radio network node for determining a channel quality offset for a radio channel for sending data from the first radio network node to a user equipment are provided. The first radio network node receives from the user equipment channel quality information for the radio channel. The first radio network node estimates resource utilization and signal-to-noise-ratio for the user equipment. The first radio network node determines the channel quality offset based on the received channel quality information, the estimated resource utilization and the estimated signal-to-noise-ratio.

A method in a radio network node for determining a channel quality offset for a radio channel used for sending data from the radio network node to a user equipment, the method comprising:
- receiving channel quality information from the user equipment for the radio channel;
- estimating a signal-to-noise-ratio for the user equipment and a resource utilization;
- and
- determining the channel quality offset based on the channel quality information, the resource utilization, and the signal-to-noise-ratio.
An arrangement in a radio network node for determining a channel quality offset for a radio channel used to send data from the radio network node to a user equipment, the arrangement comprising:
- a receiving unit configured to receive from the user equipment channel quality information for the radio channel;
- and
- a processing unit configured to:
- estimate resource utilization and a signal-to-noise ratio for the user equipment;
- and
- determine the channel quality offset based on the channel quality information, the resource utilization and the signal-to-noise-ratio.
