Abstract
Forskjellige fremgangsmåter og systemer for å bestemme returlinkdatarater i et flerbrukers kommunikasjonssystem omfatter blant annet et apparat for kontroll/styring av dataraten for minst ett første brukerutstyr UE i et slikt system, og dette apparat kan omfatte en kanalestimeringsenhet som er innrettet for å bestemme kanalestimater for flere returlinksignaler for å frembringe flere kanalestimater. Apparatet kan videre ha en demodulator for å få bestemt et første signal/støyforhold (SNR) for det første brukerutstyr UE og ved bruk av flere forskjellige kanalestimater, og videre kan apparatet ha en enhet for å bestemme datarate, særskilt en første datarate i en returlink for det første brukerutstyr UE og ved bruk av det første signal/støyforhold SNR.
