Abstract

A node in a wireless communication system comprising at least a first cell region and a second cell region, where cell borders delimit between different cell regions. The node comprises at least a first antenna function with a first antenna radiation lobe and a second antenna function with a second antenna radiation lobe, the radiation lobes being arranged to cover the first cell region at the same time. For each cell region, only one of the antenna radiation lobes is intended for communication at each cell border. Furthermore, the first antenna radiation lobe is arranged for signals at a first frequency band, and the second antenna radiation lobe is arranged for signals at least a second frequency band.
