Abstract

Teknikker for å sende sektor/systeminformasjon i TDM-piloter ved bruk av en hierarkioppbygget pilotstruktur, der en basestasjon sender flere bitsett for denne informasjon i flere TDM piloter. Bitsettene sendt i en gitt TDM pilot kan innbefatte bit sendt i tidligere TDM piloter. Basestasjonen kan generere en første TDM pilot basert på et første bitsett, en andre slik pilot basert på et andre bitsett som innbefatter det første, en tredje TDM pilot basert på samtlige bit for informasjonen og sender deretter disse piloter. En terminal utfører deteksjon for å komme frem til en første detektert verdi for den første TDM pilot, utfører deteksjon basert på den første detekterte verdi for å komme frem til en andre detektert verdi for den andre TDM pilot, og deretter utføres deteksjon basert på den første og andre detekterte verdi for å komme frem til en tredje detektert verdi for den tredje TDM pilot.
