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.

1. A method for probing of alternative antenna configurations in a communication network system comprising a plurality of communication network nodes communicating with one or more user equipments, where each network node is serving at least one cell in which the user equipments are situated via two or more reconfigurable physical antennas configured according to an initial antenna parameter set, characterised in that the method comprises the steps of:
making one of the reconfigurable physical antennas of the at least one cell temporarily available for probing; preparing the available reconfigurable physical antenna for probing by reconfiguring one or more antenna parameters thereof in accordance with a probing antenna parameter set; transmitting a new probe cell from the prepared reconfigurable physical antenna; collecting measurement reports from the user equipments within the at least one cell and the probe cell; evaluating the probing antenna parameter set based on the collected measurement reports; determining if the reconfigurable physical antennas of the cell shall use the probing antenna parameter set or the initial antenna parameter set; removing the probing cell and adjusting the reconfigurable physical antennas of the cell in accordance with the determination.
