A Discrete Queueing Model for Performance Analysis of Scheduling Schemes in Multi-User MIMO Systems

This paper investigates scheduling schemes for multiple antenna systems which supported both single and multi-user connections. Based on the discrete queueing models we build the mathematical one with batch arrivals and derive the closed-form expressions for performance metrics. With the proposed method, we analyze the effectiveness of three scheduling schemes for user information processing. The results of the numerical analysis allow comparing single-user and group servicing and providing such performance characteristics as average transfer delay and meaning number of users under the assumption of random value downloading file size with various discrete probability distributions. © 2019 IEEE.
