Abstract
A base station central unit control plane (CU-CP) receives, from a base station distributed unit (DU), an indication of completion of a small data transmission (SDT) procedure of a wireless device. The base station CU-CP sends, to the wireless device via the base station DU, a radio resource control (RRC) release message based on the indication of the completion.

A method comprising:
- receiving, by a base station central unit control plane (CU-CP) from a base station distributed unit (DU), a radio resource control (RRC) resume request message for a small data transmission (SDT) procedure of a wireless device;
- receiving, by the base station CU-CP from the base station DU, an indication message indicating inactivity notification and completion of the SDT procedure;
- and
- sending, by the base station CU-CP to the wireless device via the base station DU, a radio resource control (RRC) release message based on the indication message.

A system comprising:
- a base station distributed unit (DU) comprising:
- one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station DU to perform operations comprising:
- sending, to a base station central unit control plane (CU-CP), a radio resource control (RRC) resume request message for a small data transmission (SDT) procedure of a wireless device;
- receiving data associated with the SDT procedure;
- determining, based on the receiving the data, completion of the SDT procedure;
- and
- sending, to the base station CU-CP, an indication message indicating inactivity notification and the completion of the SDT procedure;
- and
- the base station CU-CP, wherein the base station CU-CP comprises:
- one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station CU-CP to:
- receive, from the base station DU, the RRC resume request message;
- receive, from the base station DU, the indication message indicating the inactivity notification and the completion of the SDT procedure;
- and
- send, to the wireless device via the base station DU, a radio resource control (RRC) release message based on the indication message.
