In this paper, we present a performance analysis for the channel capacity and outage probability of the user scheduling for multiuser multiple-input multiple-output (MIMO) systems with maximum ratio combining (MRC) exploiting the user and antenna diversities. We consider two scheduling schemes: absolute SNR-based and normalized SNR-based scheduling schemes. We propose the utilization of a transmit antenna selection scheme in multiuser MIMO systems in order to overcome the drawback of channel hardening and also to improve the system performance. We derive new closed-form expressions for the outage probability and average channel capacity of the presented schemes for two scenarios: Heterogeneous (independent non-identically distributed SNRs- i.ni.d.) and Homogeneous (independent identically distributed SNRs- i.i.d.) cases. Using mathematical analysis and numerical simulations, we compare the performances of presented schemes.
