title = "Frequency and Time Spreading for Uplink URLLC Transmission",
abstract = "We propose a new transmission scheme for uplink URLLC systems, which can coexist with the eMbb transmission while can still meet the reliability and latency requirements of the URLLC. The proposed scheme spreads the data in both time and frequency domains. The performance of the proposed system is analyzed and closed form expressions are derived. From the analytical results, we optimize the parameters including constellation levels, spreading length and transmit power to maximize the sum rate of the URLLC UE. Simulation results show that the proposed solution significantly improve the performance and the data rate can be up to 8.9 Mpbs in the LTE TDL-C nominal channel with co-existence and achieved URLLC requirements.",
