Abstract :
With the development of heterogeneous networks, concurrent transmission of Multimode-User Equipment (MUE) within multiple Radio Access Technologies (RATs) can improve transmission reliability and boost system performance. In this paper, some novel splitting strategies combining with different queuing management architectures are presented to obtain the multi-radio transmission diversity gain effectively. Two- dimensional discrete-state continuous-time Markov process is used to analyze our strategies and closed-form solutions have been made. Simulation results demonstrate that our proposed flow splitting strategies utilize the system resources efficiently and outperform current strategies.
