US 10,257,789 B2 · Method and device for determining transmit power

Abstract

There is provided a method performed by a network node for determining the transmit power to be used on a physical channel. The method comprises the step of obtaining values for the geometry factors G of a set of User Equipments, UEs. The method also comprises the step of creating, based on the obtained geometry factors and representations of the statistical moments of the geometry factors, a statistical measure G* for the set of UEs. The method also comprises the step of determining a value representing the transmission power for physical channel transmissions based on a power control expression for physical channel transmissions comprising the statistical measure G* for the set of UEs, and setting the transmission power to the determined value. A corresponding network node and a corresponding computer program is also provided.
