  Artykuł prezentuje wyniki analizy efektywności pracy schedulera obsługującego dedykowane kanały logiczne podwarstwy MAC-d systemu UMTS. Zbadano wpływ różnych opcji konfiguracyjnych, parametrów i dyscyplin obsługi implementowanych w podwarstwie MAC. Dokonano weryfikacji symulacyjnej. W oparciu o uzyskane wyniki zaproponowano optymalną konfigurację schedulera MAC-d oraz zasady multipleksji kanałów logicznych i selekcji TFC.
