Problems solved by technology

The first method introduces additional signaling overhead
The second approach is prone to poor selection of antenna parameters and / or poor identification of neighboring cells for joint optimization, leading to performance degradation (possibly resulting in reduced coverage and / or capacity of the cell)

Abstract

There is provided a method for utilizing antenna beam information. The method is performed by a network node. The method comprises acquiring antenna beam information indicative of a direction of a wireless device (WD) specific beam of the network node. The method comprises classifying the acquired antenna beam information into a cell specific beam category based on an angular difference between the direction and a direction of main lobe of a cell specific beam of the network node. The method comprises performing at least one of a load balancing action of the wireless device and a radiation beam pattern change related to the cell specific beam category.

Description

technical field [0001] Embodiments presented herein relate to antenna beam information, in particular to methods, network nodes, computer programs and computer program products utilizing antenna beam information. Background technique [0002] In a communication network, it can be a challenge to obtain good performance and capacity for a given communication protocol, its parameters, and the physical environment in which the communication network is deployed. [0003] Currently, advanced antenna settings and techniques enable ever-increasing throughput and robustness in wireless communication networks. One such technique is to shape the beams of the antenna array (ie, perform beamforming). Currently, beamforming can be achieved using so-called reconfigurable antenna systems (RAS). [0004] A cell-specific beam refers to an antenna beam pattern generated to provide cell-specific reference symbol (CRS) coverage for a cell in a communication network. The beam pattern is simila...
