Abstract
The present invention presents a method for controlling output power and reducing interference in a radio communications network wherein data transmitted over a radio interface is coded and transmitted in radio blocks. The data passes a buffer of a node before transmission. The method is characterized by a step of determining a recommended Modulation and Coding Scheme level, MCS level, based on at least one radio quality measurement. A further characterizing step is analyzing of buffer characteristics and/or radio block usage of transmission radio blocks to determine if there is a preferred MCS level compared to the recommended MCS level. The preferred MCS level is typically a more robust MCS level. The recommended MCS, level if so determined, is decreased to the preferred MCS level, and in relation to decreasing the MCS level decreasing the output power according to a predefined down regulation scheme. The interference level is reduced in the network depending on an application type.
