Abstract

En fremgangsmåte og anordning for basestasjoner (218) og abonnentenheter (213) som tillater mykoverlevering av en CDMA-reversforbindelse og som gjør bruk av en ortogonalkanalstruktur. Abonnenteriheter sender et ortogonalkodet signal over en reversforbindelse til basestasjoner. En gitt basestasjon tilveiebringer tidsstyringskontroll (510) for tidsforskyvningen av reversforbindelsessignalet. På grunnlag av minst et kriterium bestemmer en innrettingsstyrer (515) at den gitte basestasjonen bør overlevere tidsstyringskontrollen til andre basestasjoner, og sikrer en mykoverleveringsprosess. Som reaksjon på en kommando eller melding for mykoverlevering av abonnentenheten fra den gitte basestasjonen til en annen basestasjon, gjør abonnentenheten en grovtidsstyringsjustering til tidsstyringen av det kodede signalet. Abonnentenheten kan foreta fintidsstyringsjusteringer på grunnlag av tilbakekobling fra den basestasjonen som kontrollerer tidsstyringen. Flere basestasjoner kan tilveiebringe effektstyringstilbakekobling til abonnentenheten.
