摘要：

In the paper, we study the problem of multiplexing Ultra-Reliable Low-Latency Communications (URLLC) and enhanced Mobile Broadband (eMBB) traffic in the downlink channel of 5G systems. The Multi-User Multiple Input Multiple Output (MU-MIMO) technology is used for multiplexing, which allows a base station to transmit data simultaneously to several users in the same time-frequency resources. We propose a new algorithm (scheduler) that allocates time-frequency resources and transmission parameters for eMBB and URLLC users and dynamically distributes the base station transmission power between users. Simulation shows that the proposed scheduler increases the coverage for URLLC users and the throughput for eMBB users compared with the existing schedulers.
