Abstract
Method performed by a network node in communication with a first wireless device. The network node and the first wireless device operate in a wireless communications network. The network node determines whether or not a random access procedure for the first wireless device was successful. The determining is performed after the following actions in the random access procedure: a) a first Physical Downlink Control Channel, PDCCH, order indicating a non-reserved signal has been sent to the first wireless device, the signal being one of: a preamble, a tone and a subcarrier, and b) an L2/L3 message has been received after the sending of the first PDCCH order. The determining is based on verifying whether or not the L2/L3 message originated in the first wireless device.
