Abstract

Et trådløst kommunikasjonssystem, fremgangsmåte og apparat er gitt for myk og mykere overrekkelse av en mobil trådløs sender-/mottakerenhet (WTRU) mellom to eller flere basestasjoner og/eller basestasjonssektorer. En nettverkskontrollenhet tildeler valgte basestasjoner til å sende kommunikasjonsdata til WTRU, basert på at WTRU er utlagt i basestasjonen eller basestasjonens sektors geografiske område for tjeneste. En WTRU felles detektor (JD) mottaker er konfigurert til å motta og prosessere en eller flere trådløse datasignaler i hver av en serie av tidsrammer hvor hvert signal som er mottatt innenfor et felles tidsvindu har en unik kanalkoding av de samme kommunikasjonsdata. JD mottakeren har et flertall av kanalestimatorer som estimerer mottatte signaler innenfor et felles tidsvindu og en kombinerer konfigurert til å dekode og å kombinere kanalestimatene for å utlede et resulterende datasignal.
