A cellular network comprises a plurality of base nodes, including an active base node, to which the wireless device is currently associated. The wireless device transmits data according to a periodicity related transmission mode to the active base node. The method comprises providing information from wireless device to the active base node relating to periodicity of said data transmission, responding at the active base node comprising an indication of assigned resources for multiple transmissions, setting a timer at the active base node relating to said periodicity, upon expiration of the timer, reserving resources at the active base node for reception of the data transmission, transmitting data from the wireless device according to the periodicity, receiving transmitted data at active base node, conducting an acknowledging procedure at the active base node in response to said data reception.
