Recently, D2D (Device-to-Device) communication and MTC (Machine-Type Communication) in
LTE-Advanced networks have become a promising technologies. In D2D communication, interference
between cellular and D2D links should be controlled while guaranteeing QoS (Quality-of-Service) of
communication service. In MTC, network congestion due to the mass concurrent access requests generated
by MTC devices should be controlled while guaranteeing QoS of traditional cellular communication. In this
paper, we provide an overview of resource management mechanisms for D2D communication and MTC.
Besides, we investigate the performance of a typical mechanism of congestion control for MTC. EAB
(Extended Access Barring) mechanism barring the radio access of the devices according to the their ACs
(Access Classes) releases the overload and congestion of RA (Random Access) channel temporarily
However, the mechanism brings about the high probability of RA procedure failure and degrades the
network performance severely
