On the utilization of voice-unused resource for data transmission in PRMA systems
Youshi Xu, Peter Nilsson, H. Wiklund · 2002
In the paper voice-unused resource in a voice-only PRMA system is analyzed. A mechanism for the detection of voice-unused resource is proposed. How to use the voice-unused resource for data transmission is proposed. Therefore, the voice subsystem is totally a voice-only PRMA system, and the existence of data transmission just improves the channel utilization efficiency, without any influence on the performance of voice communications. Simulation results show that a significant amount of data traffic can be supported by the voice-unused resource.
