Abstract

Embodiments of an eNodeB and method for small data transfer in a Wireless Network are generally described herein. A method performed by circuitry of a User Equipment (UE) can include determining, by the UE, whether the UE is configured to be used for Machine Type Communication (MTC). The method can include determining whether the UE has small data (SD) to transfer. The method can include configuring the UE to use a small data signaling radio bearer (SDSRB) to send the SD, in response to determining that the UE is configured to be used for MTC and the UE has SD to transfer. An evolved Node B can determine whether the UE is configured to be used for MTC, determine whether there is SD to transfer to the UE, wherein SD comprises data that has delay tolerance, and configure the UE to use a signaling bearer to send the SD.
