INCREASING A SECTORIZATION ORDER IN A FIRST SECTOR OF AN ANTENNA ARRAY

摘要

An object of the present invention is to provide a mechanism for increasing a sectorization order in a first sector of an antenna array (120). The object is achieved by a method in a network node (130). The network node (130) and antenna array (120) are comprised in a wireless communication system (100). The antenna array (120) is deployed with a first sectorization. The network node (130) comprises a first number of signal connections (301-308). Each signal connection (301-308) is adapted to transmit and receive signals. The method comprises the step splitting (601) the first number of connections (301-308) into a number of groups (321- 322). Each one of the respective connection groups (321-322) corresponds to one respective virtual sector (411, 412) resulting in a number of virtual sectors (411-412). The method further comprises the step of mapping (603) the number of virtual sectors (411-412) to the first sector (410), such that the first sector (410) is split into the number of virtual sectors (411-412).
