Abstract

Oppfinnelsen angår en fremgangsmåte for å utføre en overlevering mellom underceller(122B, 122A) i en basestasjon. (100) som benytter dynamisk kanaltildeling i et celledelt radionett. Basestasjonen (100) omfatter underceller (122A, 122B, 122C) som hver haren antenneenhet (118A, 118B, 11C) med en fast forbindelse til basestasjonen (100). Basestasjonen omfatter sender/mottakere (TRX1-TRXN) som er innrettet for å måle mottakingseffekt fra en radioforbindelse (200) med en abonnentterminal (102). Når den målte mottakingseffekten faller under en forhåndsbestemt grense, vil mottakingseffekten for et signal 224A som sendes fra abonnentterminalen (102) på radioforbindelsen (200), bli målt i sin tur via antenneenheter (118C, 118A) i andre underceller (122C, 122A) enn den betjenende undercellen. En overlevering mellom undercellene (122B; 122A) utføres når en antenneenhet (118A) som gir bedre mottakingseffekt, blir funnet. Et svitsjefelt (116) i basestasjonen. (100) omfatter svitsjer (220) for å kombinere signaler (224B, 224A) som sendes på radioforbindelsen (200) fra abonnentterminalen (102) og mottas via den betjenende undercellens (122B) antenneenhet (118B) og en annen undercelles (122A) antenneenhet (188A), for å generere et kombinert signal (230). Det kombinerte signalets (230) mottakingseffekt blir målt, og på grunnlag av en sammenligning mellom de målte mottakings-effektene for det kombinerte signalets (230) og den betjenende cellens (122B) signal (224B), konkluderer styringsenheten (114) med hvilken antenneenhet (118A) i den andre undercellen (122A) som en overlevering skal foretas til.
