Coexistence of H2H and M2M terminals in a LTE/LTE- A cellular network is severely limited by the random access scheme prescribed by the standard. In this paper, we describe an overlay scheme for concurrent M2M and H2H access on PRACH in which M2M terminals use a subset of ZC codes for its PHY layer and a beacon enabled CSMA-CA mechanism similar to IEEE 802.15.4 for its MAC layer. We analyze the performance of the proposed scheme and show that it provides satisfactory capacity for both H2H and M2M traffic.
