Patent ID: 7170874

Claim:
A method for transmission having improved overall spectral efficiency in a wireless telecommunication system, comprising—transmitting at least one multiframe signal having a plurality of sub-frames, wherein: three or more predefined logical channels including a frequency correction channel FCCH and a synchronization channel SCH are repeatedly embedded in predefined sub-frames; the step of transmitting comprises—applying transmitting diversity using at least one of antenna hopping sequences and polarisation hopping sequences, such that during the transmission of at least one said multiframe signal, each logical channel is transmitted at least twice on different antennas and/or with different polarisations; if antenna hopping sequences are used, at least one antenna hopping sequence is applied such that each time an antenna is selected for FCCH the same antenna is selected for SCH; and if polarisation hopping sequences are used, at least one polarisation hopping sequence is applied such that each time a polarisation is selected for FCCH the same polarisation is selected for SCH.
