A first radio access network, RAN, node in a communication network can determine whether to provide dual connectivity to a user equipment, UE, in the communication network based on an UL quality. The first RAN node can receive data indicating characteristics of an uplink, UL, channel of one or more UL channels for a second RAN node in the communication network. The first RAN node can estimate an UL quality of the UL channel based on the data. The first RAN node can determine based on the UL quality, whether to provide dual connectivity to the UE in the communication network by adding the second RAN node as a secondary node serving the UE.

Uplink aware dual connectivity

An antenna system () comprises a Centralized Processing Unit (); at least two antenna units () connected to the CPU () by cables. Each antenna unit () comprises at least one connector; one or more antenna elements () and one or more 5 Antenna Processing Units () connected to the one or more antenna elements (). The one or more antenna processing units () are connected to a data bus connected to the at least one connector.
