Abstract

Oppfinnelsen angår en fremgangsmåte for datatransmisjon i et celledelt radiosystem av CDMA-typen, som omfatter i hver celle minst en base- stasjon (10) som kommuniserer med mobilstasjoner (11, 12) innenfor sitt dekningsområde, og i hvilket system basestasjonen justerer sendeeffekten for de mobile stasjoner innenfor området ved hjelp av effektstyrings-meldinger. For å muliggjøre sammen- hengende deteksjon også ved basestasjonen, dvs. i oppoverretning (fra mobilstasjon til basestasjon) blir transmisjonen på trafikk-kanalen, i henhold til fremgangsmåten utført både i retning fra mobil- stasjonen til basestasjonen og fra basestasjonen til mobilstasjonen ved bruk av en lignende rammestruk- tur. Når basestasjonen sender en effektstyrings- melding til den mobile stasjonen ved å bruke biter av rammestrukturen for trafikk-kanalen, sender mobilstasjonen et forut bestemt bitmønster til basestasjonen i de tilsvarende biter i den andre transmisjonsretning for trafikk-kanalen.
