摘要： Devices, methods and computer programs for small data transmission, SDT, transaction termination are disclosed. A client device determines whether an ongoing small data transmission, SDT, transaction comprising one or more uplink, UL, small data transmissions with a control plane network node device is to be terminated. If yes, a radio resource control, RRC, message comprising termination information related to the determined termination of the ongoing SDT transaction is forwarded from the client device to the control plane network node device.
