Abstract

Oppfinnelsen angår en fremgangsmåte for måling av signal-taktstyring, samt et CDMA-radiosystem som implementerer fremgangsmåten. Data om minst en kodekanal som sendes fra en nabobasestasjon (104, 106), befordres til en ter- minal (100) via en betjenende basestasjon (102). På grunnlag av disse data be- stemmer terminalen (100) i det minste spredningskoden for hver slik kodekanal, samt et estimat av symbol-taktstyringen, i forhold til taktstyringen i den betjenende basestasjonen (102). Terminalen utnytter minst noen av nabobasestasjonens ¿ (104, 106) kodekanaler for å måle nabobasestasjonens (104, 106) signal-taktsty- ring. På grunnlag av tidsmålingen bestemmes for eksempel terminalen (100) lokasjon.
