Radio Network Node, a Controlling Radio Network Node, and Methods Therein for Enabling Management of Radio Resources in a Radio Communications Network

A method in a radio network node or enabling management of radio resources in a radio communications network, which radio network node serves a first cell, the method comprising:

• measuring a received total power value at the radio network node in the first cell;
• computing a factor indicating a load in the first cell;
• estimating a noise floor level in the first cell;
• and
• computing a utilization probability value of the load in the first cell and a neighbour cell interference value simultaneously in a non-linear interference model based on the measured received total power value, the computed factor, and the estimated noise floor level in the first cell, which neighbour cell interference value is an interference from at least one second cell affecting said first cell, and where at least one of the utilization probability value of the load in the first cell and the neighbour cell interference value is to be used for managing radio resources in the radio communications network.

A radio network node for enabling management of radio resources in a radio communications network, wherein the radio network node is configured to serve a first cell and comprises:

• a measuring circuit configured to measure a received total power value at the radio network node in the first cell;
• a first computing circuit configured to compute a factor indicating a load in the first cell;
• an estimating circuit configured to estimate a noise floor level in the first cell;
• and
• a second computing circuit configured to compute a utilization probability value of the load in the first cell and a neighbour cell interference value simultaneously in a non-linear interference model based on the measured received total power value, the computed factor, and the estimated noise floor level in the first cell, which neighbour cell interference value is an interference from at least one second cell affecting said first cell, and where at least one of the utilization probability value of the load in the first cell and the neighbour cell interference value is to be used for managing radio resources in the radio communications network.
