The present invention relates to an arrangement, a communication network node and a user equipment allowing for maintaining cell coverage in a communication network system as well as a method for such maintained cell coverage. The communication network system comprising a plurality of communication network nodes (15a, 15b) communicating with one or more user equipments (18), where each network node (15a, 15b) is serving at least one cell (19) in which the user equipments (18) are situated. The method comprises the steps of: collecting (51) measurement reports from the user equipments (18) within the at least one cell (19); analyzing (52) collected measurement reports from at least some of the user equipments (18) for determining the proximity of these user equipments (18) to an uplink cove rage limit (20); setting (53) a noise rise threshold based on the determined proximity of these user equipments (18) to the uplink coverage limit (20); implementing (55) the set noise rise threshold in the network node (15a, 15b) serving the at least one cell (19).
