This paper investigates the coexistence of M2M and H2H based traffic sharing the RACH of an existing cellular network. Q-learning is applied to control the RACH access of the M2M devices which enables collision free access amongst the M2M user group. Frame ALOHA for a Q-learning RACH access (FA-QL-RACH) is proposed to realise a collision free RACH access between the H2H and M2M user groups. The scheme...
This paper introduces the concept of virtual cells in Time-Division Long Term Evolution (TD-LTE) systems, which enables users residing in overlapping cells' coverage regions to utilize resources from multiple base stations. The benefits of virtual cells are realized by the efficient resource utilization, via adapting the network resource availability with the traffic demand taking also into account...
