Abstract
The present invention relates to an arrangement, a communication network node and method for cell outage compensation in a communication network system comprising a plurality of communication network nodes (15a, 15b) communicating with user equipments (18), where each network node (15a, 15b) is serving at least one cell (19a, 19b), in which the user equipments (18) are situated, via two or more reconfigurable physical antennas (15a1, 15a2, 15b1, 15b2) configured according to an initial antenna parameter set. Cell outage is determined in a network node (15b). One of the reconfigurable physical antennas (15a2) of at least one cell (19a) is made temporarily available for compensation. The available antenna (15a2,) is prepared for compensation by reconfiguring one or more antenna parameters thereof in accordance with a compensating antenna parameter set. A new compensating cell (20) is transmitted from the prepared antenna (15a2). Upon cell recovery the compensating cell (20) is removed and the reconfigurable physical antennas (15a2) of the compensating cell (20) returned to the initial antenna parameter set.
