Method and apparatus for transmission diversity in wireless telecomunication systems providing antenna and/or polarisation hopping sequences

摘要

The invention relates to the overall spectral efficiency of wireless telecommunication systems.;It is an object of the invention to provide a new and improved approach for reducing the necessary cluster size needed for logical channels and hence, to significantly increasing the overall spectral efficiency.;The invention proposes for improving the overall spectral efficiency of wireless telecommunication systems, in particular of mobile communication systems, the transmission of at least one multiframe signal having a plurality of sub-frames with predefined logical channels (BCCH, FCCH, SCH) repeatedly embedded in predefined sub-frames, wherein a transmitter diversity is applied using antenna and/or polarisation hopping sequences such that during the transmission of respective one multiframe, each logical channel (BCCH, FCCH, SCH) is transmitted at least two times with a different antenna and/or polarisation.
