The spectrum efficiency can be greatly enhanced by the deployment of machine-to-machine (M2M) communications through cellular networks. Existing resource allocation approaches allocate maximum blocks (RBs) for user equipments (CUEs). However, M2M (MUEs) share same frequency among themselves within tier. This results in generating co-tier interference, which may deteriorate MUE's quality-of-service (QoS). To tackle this problem and improve experience, paper, we propose a novel utilization...
