Enhanced establishment of communication between nodes in a communication system

A first network node adapted to establish communication between the first network node and a wireless device in a wireless communication system, wherein the first network node comprises a directive antenna, the first network node being adapted to:

• receive information related to a geographic location of the wireless device using a first beam that is wider than any beam included in a group of one or more beams, wherein the information related to the geographic location of the wireless device was transmitted by the wireless device;
• based on the geographic location of the wireless device, determine an antenna configuration of the first network node for communicating with the wireless device via the directive antenna, wherein determining the antenna configuration of the first network node comprises selecting from a plurality of beams the group of one or more beams to use for receiving a sounding reference signal transmitted by the wireless device;
• and
• using the determined antenna configuration, communicate with the wireless device via the directive antenna, wherein communicating with the wireless device comprises receiving the sounding reference signal transmitted by the wireless device using the group of one or more beams.
