Abstract
A method for handling a Mobile Terminating (MT) Small Data Transmission (SDT) from a network node to a user equipment (UE) in a wireless communications network. The UE receives a Downlink Control Information (DCI) from the network node. The DCI is identified when monitoring a Physical Downlink Control Channel (PDCCH) by means of a Cell-Radio Network Temporary Identifier (C-RNTI). The DCI indicates scheduled Downlink (DL) data related to the SDT. Further, the DCI is received when the UE has entered into an inactive mode. When the DCI has been received, the UE resumes the radio resources configured for a Configured Grant based SDT (CG-SDT) in the UE context, derives a new security key based on a security key present in the UE context, and when receiving the scheduled DL data related to the MT-SDT from the network node, the UE decrypts the DL data by means of the new security key.
