Abstract
According to the present invention, a method in a base station is provided for predicting interference contribution, when scheduling an uplink data packet transmission from a first user equipment. The first user equipment is connected to the base station. The first user equipment is in the neighbor of a neighboring cell served by a neighboring base station. The method comprises the steps of: Obtaining signal strength measurements regarding the first user equipment. The signal strength measurements are based on a signal between the first user equipment and the neighboring base station; Receiving a resource scheduling request regarding the first user equipment for the uplink data packet transmission; Scheduling uplink resources for the requested uplink data packet transmission; Determining transmission power to be used for the scheduled uplink resources, and: Estimating an interference prediction contribution based on the determined transmission power and the obtained signal strength.
