Patent ID: 7907588

Claim:
A method of reducing a peak to average power ratio of a signal, said signal comprising data designated for transmission to a sector of a plurality of sectors, said method comprising: selecting a first subset of radio resources from a given set of radio resources, wherein the first subset of radio resources is employable in all sectors of the plurality of sectors for peak to average power reduction; and assigning a subset of radio resources from the remaining set of radio resources to each sector of said plurality of sectors; wherein a subset of radio resources which is assigned to a sector is at least approximately disjoint from a subset that is assigned to another sector of said plurality of sectors, the method further comprising: generating a first auxiliary signal by combining the data with the subset of radio resources assigned to the sector; generating a second auxiliary signal by combining the first subset of radio resources with auxiliary data; and generating said signal by a superposition of the first auxiliary signal and the second auxiliary signal, wherein the auxiliary data is determined such that the peak to average power ratio of the signal is reduced with respect to the peak to average power ratio of the first auxiliary signal.
