Abstract

I et system (10) for trådløs kommunikasjon og hvor det er en felles transportkanalgruppe som består av flere enkelte transportkanaler utføres effektregulering i lukket sløyfe ved at flere trinn i en ytre sløyfe utføres i parallell. Et signal/inter-ferensforhold (SIR) danner en terskel for felles-kanalen, basert på en kanalkvalitetsverdi som utledes for hver enkelt av transportkanalene. I en bestemt utførelse av dette system (10) er denne kanalkvalitetsverdi resultatet av en syklisk redundanskontroll (CRC).
