Abstract

Sendingseffektnivåer for opplink/nedlink kommunikasjon blir konttollert i et ttådløst kommunikasjonssystem. En motlagende stasjon produserer og gir til en sendende stasjon effektkonttollinformasjon basert på mottatte signaler fra den sendende stasjonen. En målt blokkfeilrate (BLER n) blir funnet fra antallet av feilaktige blokker i et ghdevindu på i det minste N mottatte datablokker og SIR justeringer er satt basert på BLERj, og en målsatt BLER (BLERta,g,t). En målsatt SIR for mottatte signaler blir justert i henhold til SIR justeringene.
