Radio network node, a controlling radio network node, and methods therein for enabling management of radio resources in a radio communications network

Abstract

Embodiments herein relate to a method in a radio network node (12) for enabling management of radio resources in a radio communications network, which radio network node (12) serves a first cell (11). The radio network node measures a received total power value at the radio network node (12) in the first cell (11). The radio network node (12) computes a factor indicating a load in the first cell (11). The radio network node (12) estimates a noise floor level in the first cell (11). The radio network node (12) computes a utilization probability value of the load in the first cell (11) and a neighbor cell interference value simultaneously in a non-linear interference model. This is based on the measured received total power value, the computed factor, and the estimated noise floor level in the first cell (11), which neighbor cell interference value is an interference from at least one second cell (14) affecting said first cell (11), and where at least one of the utilization probability value of the load in the first cell (11) and the neighbor cell interference value is to be used for managing radio resources in the radio communications network.
