5G technology is designed to resolve issues such as the growth of mobile traffic, the increase in the number of devices connected to the network, reducing delays for the implementation of new services and the lack of a frequency spectrum. The main services in future 5G networks are enhanced Mobile Broadband (eMBB), massive Machine Type Communications (mMTC) and Ultra Reliable Low Latency Communications (URLLC). In this paper, we consider two cases of joint eMBB and URLLC transmissions. In the first case, when all resources are occupied, the blocking of new requests happens, and in the second case, it is possible to reduce the transmission speed of the eMBB application and accept the new URLLC request for service.
