METHOD AND ARRANGEMENT FOR PROBING OF ALTERNATIVE ANTENNA CONFIGURATIONS IN A COMMUNICATION NETWORK SYSTEM

摘要

The present invention relates to an arrangement, a communication network node and a user equipment allowing for probing of alternative antenna configurations in a communication network system as well as a method for such probing. The method comprises making one of the reconfigurable antennas (15a2, 15b2) of at least one cell (19a, 19b) temporarily available for probing and reconfiguring one or more antenna parameters thereof in accordance with a probing antenna parameter set. A new probe cell (20a, 20b) is transmitted from the prepared antenna (15a2, 15b2) and measurement reports collected from the user equipments (18) within the at least one cell (19a, 19b) and the probe cell (20a, 20b). The probing antenna parameter set is evaluated based on the collected measurement reports whereupon is determined if the reconfigurable physical antennas (15a1, 15a2, 15b1, 15b2) of the cell shall use the probing antenna parameter set or the initial antenna parameter set. Finally the probing cell (20a, 20b) is removed and the antennas (15a1, 15a2, 15b1, 15b2) adjusted in accordance with the determination.
