A method of evaluating transmission power for transmission of a message between a first network node and a second network node in a multicarrier wireless communications system in which a predetermined set of a plurality of carriers are utilised to support communication between said first network node and said second network node, said predetermined set of said plurality of carriers comprising a primary carrier and at least one secondary carrier. The method comprises the steps of: determining an initial indication of appropriate power setting to enable a message to be transmitted between said first and second network nodes on said primary carrier; determining that there is a message to be sent between said first and second network node at a transmission time after receipt of said initial indication; and evaluating, based on said initial indication, an appropriate power setting to enable a message to be transmitted between said first and second network nodes on said primary carrier at said transmission time. Accordingly, a network node may be operable to evaluate an estimation of required transmission power to ensure a message reaches a second network node, even without frequent updates of usually received power control messages.
