Probability model for perfomance analysis of joint urllc and eMBB transmission in 5G networks

The eMBB and URLLC collaboration system with two models of resource allocation planning is considered. Poisson streams of two types of traffic arrive at the system input. The system is determined by the following parameters: the number of resource blocks, the number of resource units, the maximum number of URLLC sessions in one block with an eMBB session. The discipline of servicing the first model is defined as follows: the system receives applications eMBB and URLLC, with free resources all types of traffic are accepted. In the absence of free resource blocks, new eMBB sessions are blocked. In the absence of free single resources and at least one eMBB session, the new URLLC session blocks the active eMBB session. In the absence of free single resources and the absence of active eMBB sessions in the system, the new URLLC session is blocked. The service discipline of the second model is determined in a similar way with the following exception: in the absence of free unit resources and the presence of at least one eMBB session and the condition is met for the maximum number of URLLC sessions in one block with an eMBB session, then the URLLC session is superimposed on the eMBB session. In the absence of free single resources and the presence of at least one eMBB session, the condition for the maximum number of URLLC sessions in one block with the eMBB session is not fulfilled, then the eMBB session is blocked to serve the URLLC session. The paper presents the results of a numerical analysis of the probability-time characteristics of two models.
