Abstract

Oppfinnelsen angår en fremgangsmåte for sending av en synkronisert ka- nal i en radiosender, samt en radiosender. Fremgangsmåten omfatter sending (606) av normale radioskurer på en normal kanal asynkront, l oppfinnelsen opp- nås det (702) synkronisert taktstyring, synkroniserte radioskurer (SB) blir dannet (708), og en synkronisert radioskur blir sendt (710) istedenfor en normal radioskur (NB). Lengden av den synkroniserte radioskuren (SB) er høyst halvparten av lengden av den normale radioskuren (NB). Sendingen av den synkroniserte radio- skuren (SB) er i synkronisme med den oppnådde, synkroniserte taktstyringen.
