An Enhanced Random Access With Preamble-Assisted Short-Packet Transmissions for Cellular IoT Communications

We propose an enhanced random access (RA) with preamble-assisted short-packet transmissions to support cellular Internet-of-Things (IoT) communications. A key feature of the proposed scheme is that the base station (e.g., eNodeB in LTE networks) utilizes the RA preambles as uplink reference signals...
