The present invention relates to a method for energy saving in a telecommunication system with at least one first base stationfor enabling communication within a first cell. A signal having a frame structure is transmitted in the first cell by the first base station. The structure of at least some frames comprises an overhead part with at least synchronization or system information. The first base stationis in a normal mode operated to transmit at least the overhead part so that it substantially reaches all user terminals within the first cell covering a first area. The method is particularly characterized in that the first base stationin a power saving mode is operated to transmit at least the overhead part so that it substantially reaches all user terminals within the first cell covering a second areabeing larger than the first area

Method for energy saving in a telecommunication system

A central unit for a multi-carrier system receives both multi-carrier and single carrier signals. The single carrier wave is a carrier wave that is part of the multi-carrier system for which the central unit is designed. The central unit schedules transmission from the single-carrier equipment in interaction with the single-carrier equipment.
