Abstract

The present invention relates to exchanging a cell-specific parameter such as the A-MPR, comprising information related to a required additional maximum power reduction of a UE transmitter between networks nodes. The networks nodes may be radio base stations or other network nodes such as radio network controllers or core network nodes exemplified by access gateways (aGWs). By exchanging this cell- specific parameter with information of the required additional maximum power reduction between the network nodes, the cell-specific parameter is provided to the radio base station of the serving cell which implies that the serving cell can send the cell-specific parameter of the target cell to the UE prior to the handover from the serving cell to the target cell. This result in that the UE can start transmission to the target cell with the correct cell-specific parameter and the out-of-band emission requirements can be fulfilled in the target cell.

Description

technical field [0001] The present invention relates to methods and arrangements in telecommunication systems, in particular to methods and arrangements for providing A-MPR related information on handovers in wireless telecommunication systems. Background technique [0002] Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) is a radio network of the UMTS system, one of third generation (3G) mobile communication technologies, designed to succeed GSM. UTRAN uses W-CDMA as a potential radio interface. [0003] The Evolved UMTS Terrestrial Radio Access Network (E-UTRA), also known as LTE (Long Term Evolution), was standardized by the Third Generation Partnership Project (3GPP) Long Term Evolution (LTE), which is an improvement within 3GPP with high-speed packet access A project of the Universal Mobile Telecommunications System (UMTS) standard for functionalities to address further demands in terms of improved services such as higher data ...
