Abstract
A method performed by a first radio node for selecting a transmission rank is provided. The radio node is capable of using at least a first antenna beam and a second antenna beam for communication with a second radio node in a wireless communication network. The radio node communicates with the second radio node by using the first antenna beam and a first transmission rank. The radio node obtains second radio parameters for the second antenna beam. The radio node then selects a second transmission rank based on the obtained second radio parameters. The second transmission rank is to be used for communication with the second radio node in the second beam. The selection of the second transmission rank is triggered before obtaining any Rank Indicator (RI) for the second antenna beam.
