Abstract
The invention relates to a method of reducing a peak to average power ratio of a signal, wherein the signal comprises data that is designated for transmission to a sector of a plurality of sectors, and wherein the method comprises the steps of selecting a first subset of radio resources from a given set of radio resources and of assigning a subset of radio resources from the remaining set of radio resource to each sector of said plurality of sectors. Each subset of radio resources is at least approximately disjoint from another subset of radio resources. The method in accordance with the invention further comprises the step of generating the signal by combining the data on the subset of radio resources that has been assigned previously to the sector and by employing said first subset of radio resources for a reduction of the peak to average power ratio. In another aspect the invention relates to a communication network component, to a computer program product and to a wireless communication system.
