| 摘要 |
The invention relates to a method for interference reduction in a radio communication system (RCS). The radio communication system (RCS) comprises a first cooperating transmission antenna system (CTAl) provided by at least two antenna arrays (AAl, AA2) and a second cooperating transmission antenna system (CTA2) provided by at least two further antenna arrays (AA3, AA4). The method comprises the steps of transmitting from the first cooperating transmission antenna system (CTAl) first radio frequency signals by a first coordinated multipoint transmission (CMT1) to a first mobile station (MSI), and adapting at the second cooperating transmission antenna system (CTA2) at least one transmit weight for a second coordinated multipoint transmission (CMT2) with second radio frequency signals (RFS2) from the second cooperating transmission antenna system (CTA2) to a second mobile station (MS2) based on a channel state of an interference channel (IC) of the second radio frequency signals between the second cooperating transmission antenna system (CTA2) and the first mobile station (MSI) providing interference to the first radio frequency signals. The invention further relates to a first radio access network node (RA-NN1), to a second radio access network node (RA-NN2) and to a mobile station (MSI, MS2) for use in the radio communication system (RCS). |
