A COMMUNICATION SYSTEM NODE WITH IMPROVED INTERFERENCE SITUATION

摘要

The present invention relates to a node (1) in a wireless communication system (2) comprising at least a first cell region (3a) and a second cell region (3b), where cell borders (11, 12) delimit between different cell regions (3a, 3b, 3c). The node (1) comprises at least a first antenna function (4a) with a first antenna radiation lobe (5a) and a second antenna function (6a) with a second antenna radiation lobe (7a), the radiation lobes (5a, 7a) being arranged to cover the first cell region (3a) at the same time. For each cell region (3a, 3b, 3c), only one of the antenna radiation lobes (5a, 7a) is intended for communication at each cell border (11, 12). Furthermore, the first antenna radiation lobe (5a) is arranged for signals at a first frequency band (f1), and the second antenna radiation lobe (7a) is arranged for signals at at least a second frequency band (f2), where, for each cell region (3a, 3b, 3c), only one antenna radiation lobe is intended for communication at each cell border (11, 12, 13; 24, 25).
