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.A method and apparatus for base stations (218) and subscriber units (213) which permit the soft transmission of a CDMA reverse connection and employing an orthogonal channel structure. Subscriber units send an orthogonal encoded signal over a reverse connection to base stations. A given base station provides time control (510) control for the time offset of the reverse link signal. On the basis of at least one criterion, an alignment controller (515) determines that the given base station should hand over the timing control to other base stations, and ensures a soft handover process. In response to a command or message for soft handover of the subscriber unit from the given base station to another base station, the subscriber unit makes a coarse timing adjustment to the timing of the encoded signal. The subscriber unit can make fine-time management adjustments on the basis of feedback from the base station controlling the time management. Several base stations can provide power control feedback to the subscriber unit.
