Abstract
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.

21. A user equipment (UE) comprising:
-
processing circuitry arranged to determine a size of data to be transmitted by the UE; and characterize the data as small data if the size of the data is below a threshold; and physical layer circuitry to be configured by the processing circuitry, responsive to the characterizing, to transmit a message indicating that the UE shall be transmitting small data; and transmit small data subsequent to receiving a notification that a small data radio bearer (SDRB) has been configured for transmission of the small data. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. An evolved NodeB (eNodeB) comprising:
a transceiver arranged to receive a Radio Resource Control (RRC) connection request from a user equipment (UE) indicating that the UE shall be transmitting small data, and transmit, subsequent to receiving the request, a response to the request that includes a logical channel identifier (LCID) of a small data radio bearer (SDRB) for use in transmitting small data. - View Dependent Claims (31, 32)

33. A method, performed by user equipment (UE), for small data transmission, the method comprising:
-
determining that data to be transmitted by the UE is small data if a size of the data is below a threshold; transmitting 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; receiving, in response to transmitting the message, a radio resource control (RRC) signal from an evolved Node B (eNodeB) in accordance with a standard of the 3rd Generation Partnership Project (3GPP) family of standards that includes a logical channel identifier (LCID) of a small data radio bearer (SDRB) configured for transmission of small data; transmitting small data on the SDRB subsequent to receiving the RRC signal from the eNodeB; and refraining from transmitting other than small data on the SDRB. - View Dependent Claims (34, 35, 36, 37)

38. A method, performed by an evolved Node B (eNodeB), for controlling small data transmissions, the method comprising:
-
receiving a Radio Resource Control (RRC) connection request from a user equipment (UE) that includes an establishment cause field indicating that the UE shall be transmitting small data; and transmitting a response to the request that includes a logical channel identifier (LCID) of a small data radio bearer (SDRB) for use in transmitting small data. - View Dependent Claims (39, 40)
