Abstract

Method and arrangement in a first radio network node for supporting transmission power adjustment of a mobile terminal and method and arrangement in a second radio network node for assisting the first radio network node in supporting such adjustment. The first radio network node and the mobile terminal are adapted to operate on a first radio access technology. The power adjustment of the mobile terminal is performed in order to reduce interference, caused by the mobile terminal, on the second radio network node. The second radio network node is adapted to operate on a second radio access technology. The method comprises obtaining an indication that the second radio network node is interfered by transmissions from the mobile terminal, obtaining values of power control parameters for adjusting the transmission power of the mobile terminal and transmitting the obtained power control parameter values to the mobile terminal, in order to enable the adjustment of the transmission power of the mobile terminal.

Description

technical field [0001] The invention relates to a method and a device in a first radio network node and a method and a device in a second radio network node. More specifically, the present invention relates to mechanisms for reducing channel interference between co-located radio network nodes by supporting transmit power adjustment of mobile terminals. Background technique [0002] Multiple radio access technologies (RATs) are being deployed in the same geographic area by the same or different operators. There are also several frequency bands that have been standardized for various technologies. For example, according to various 3rd Generation Partnership Project (3GPP) standards, different types of technologies such as Global System for Mobile Telecommunications (GSM), UMTS Terrestrial Radio Access Network (UTRAN), Evolved UTRAN (E-UTRAN), etc. can be used in the same operating in the frequency band. There are even frequency bands where both 3GPP and non-3GPP technologie...
