Abstract

Foreliggende oppfinnelses fremgangsmåte for å kontrollere nedlinkstransmisjonseffektnivåer i et spredt spektrum tidsdelt kommunikasjonssystem som har rammer med tidsvinduer for kommunikasjon, tar imot i et brukerutstyr (UE) en nedlinkskommunikasjon fra en basestasjon og bestemmer en feilrate av den mottatte kommunikasjonen. For hver av tidsvinduene produseres effektnivåjusteringer basert delvis på feilraten, og fra UE sendes til basestasjonen en opplinjekommunikasjon som inkluderer effektnivåjusteringene for hvert av tidsvinduene. Som svar på effektnivåjusteringene, settes transmisjonseffektnivået for hvert tidsvindu i nedlinkskommunikasjonen.
