Apparatuses and methods for control of small data transmission by a user equipment (UE) are described herein. The UE may determine that data to be transmitted by the UE is small data if a size of the data is below a threshold. The UE may transmit a message indicating that the UE shall be transmitting small data responsive to determining that data to be transmitted by the UE is small data. The UE may receive a radio resource control (RRC) signal from an evolved Node B (eNodeB) that includes a logical channel identifier (LCID) of a small data radio bearer (SDRB) configured for transmission of small data. The UE may transmit small data on the SDRB subsequent to receiving the RRC signal from the eNodeB. The UE may refrain from transmitting other than small data on the SDRB. Other apparatuses and methods are described.
