Abstract

Et apparat ifølge en utførelse av oppfinnelsen omfatter en sender. Senderen omfatter et første forsterkningselement konfigurert og arrangert for å modulere et høyfrekvenssignal ifølge en første forsterkning for å produsere et første utgangsignal; og et andre forsterkningselement konfigurert og arrangert for å modulere høyfrekvenssignalet ifølge en andre forsterkning for å produsere et andre utgangssignal idet en størrelse av den første forsterkning varierer over tid og idet en størrelse av den andre forsterkning varierer over tid i forhold til en størrelse av den første forsterkning. Hver av de modulerte signalene er koplet til en respektiv antenne. Det kombinerte utstrålingsdiagram av antennene varierer i en vinkelretning over tid. I et system ifølge en utførelse av oppfinnelsen omfatter en basestasjon et apparat som mottar kanalkvalitetsindikasjoner fra mobilenheter og planlegger dataoverføringer til mobilenhetene i samsvar med dette.
