Abstract

Fremgangsmåte og apparat for å estimere og å rapportere kvaliteten i en trådløs kommunikasjonskanal mellom en trådløs sender-/mottakerenhet (WTRU) og en NodeB. Et modulert signal er mottatt fra Noden-B over kommunikasjonskanalen og et kanalestimat blir utført på det modulerte signalet for å gi et kanalestimat. I en utførelse blir det modulerte signalet demodulert basert på kanalestimatet for å gi et demodulert signal og et signal-til-interferens (SIR) estimat basert på det demodulerte signalet er fatt. Kvaliteten til kommunikasjonskanalen er estimert er estimert basert på i det minste SIRestimatet. I en alternativ utførelse er et SIR-estimat basert på kanalestimatet fatt. Kvaliteten til kommunikasjonskanalen er estimert basert på SIR-estimatet og tilleggsinforinasjon som omfatter i det minste en av forsinkelsesspredning, sendeeffekt og WTRU-hastighets informasjon.
