Abstract
It is provided a method performed in a network node of a cellular network also comprising a wireless device, the wireless device being in a discontinuous reception mode comprising receiving periods and idle periods. The method comprises the steps of: transmitting a first control signal to the wireless device during a receiving period for the wireless device; determining that a first control signal is likely to have failed to be correctly received by the wireless device; determining that a second control signal needs to be transmitted to the wireless device, the second control signal corresponding to the first control signal; applying a more robust transmission procedure for the second control signal compared to a corresponding transmission procedure for the first control signal; and transmitting the second control signal to the wireless device.
