Dynamic Multiplexing of URLLC Traffic and eMBB Traffic in an Uplink Using Nonorthogonal Multiple Access

摘要

The problem of uplink multiplexing of two different types of traffic specific to 5G networks (enhanced Mobile Broadband traffic (eMBB) and Ultra-Reliable Low-Latency Communications (URLLC)) is considered. A dynamic multiplexing scheme based on the use of the nonorthogonal multiple access is proposed. An analytical model is developed to estimate the network performance using the proposed scheme, as well as to select its optimal parameters in order to maximize the network capacity for eMBB traffic while fulfilling the quality of service requirements for URLLC traffic.
