The conventional multiplexing approaches for communication systems demand the pre-specified splitting of resources in time, frequency, space, etc. However, these existing techniques are not flexible when variable messages, such as alert or control information generated by other sources, emerges to be included for transmission during a communication session. In this paper, we propose an innovative idea, namely software-defined multiplexing coding, to efficiently accommodate emerging messages from time to time. Such a new multiplexing paradigm does not demand any additional resource and is very easy to be implemented in real time. The computational complexities of the software-defined multiplexing coding schemes are very low and the asymptotic expected code rate approaches very close to one according to our theoretical analysis.
