Access Control Enhancements for Cellular Internet of Things

Random Access (RA) is an important process in Cellular Internet of Things (CIoT), which enables the IoT devices to connect to the network for set-up and data transmission. As the number of IoT devices in the network is increasing, the competition for accessing the network increases as well. Additionally, since each IoT application may have different requirements in terms data size, latency, and data rate, it is essential to optimize the random access process to address the requirements of different applications. Therefore, there is a need to design the uplink transmission mechanism to reduce the signaling overhead being exchanged between the User Equipment (UE) and the base station. The 3rd Generation Partnership Project (3GPP) has introduced several random access process enhancements to address these issues. We will look at these enhancements in this seminar.
