Abstract
Et system og en fremgangsmåte til å optimalisere antallet opplink- og nedlinkvinduer (12, 16) gitt det maksimale antall kryssede vinduer mellom hvilke som helst to celler (10, 14) er beskrevet. Den foreliggende oppfinnelsen tildeler effektivt en retning (det vil si opplink eller nedlink) til hvert vindu (12, 16) i hver celle (10, 14) i systemet, idet det tas hensyn til avveiningen mellom a) å unngå base-til-base eller mobil-tilmobilinterferens, og b) tilpasning av vindustildelingen for hver celle som nært som mulig til de lokale trafikkbetingelser. Den foreliggende oppfinnelsen tildeler brukere til vinduer (12, 16) i henhold til deres sendeeffektkrav, for å tillate vindu-tilcelletildelinger i innbyrdes konflikt mellom to celler (10, 14) i det samme geografiske området.
