N2  - Device-to-Device (D2D) communications is expected to be a
key technology of the forthcoming mobile communication
networks because of its benefits in terms of spectral efficiency,
energy efficiency, and system capacity. To mitigate frequency
collisions as well as reduce the effects of co-channel
interference between user's connections, we propose an
interference-aware coordinated access control (IaCAC)
mechanism for heterogeneous cellular D2D communication
networks with dense device deployment of user equipment
(UEs). In the proposed network setting, we consider the
co-existence of both macro base stations (MBSs) and
smallcell base stations (SBSs). In the proposed IaCAC
mechanism, MBSs and SBSs are coordinated to perform
access control to their UEs while MBSs allocate bandwidth
parts dynamically to SBSs based on the interference levels
measured at SBSs. Besides, to reduce D2D-to-cellular
interference, device user equipments (DUEs) can perform
power control autonomously. Simulation results show that the
proposed IaCAC can provide higher system throughput and
user throughput than those achieved by the network-assisted
device-decided scheme proposed in [21]. Moreover,
simulation results also reveal that the proposed IaCAC also
significantly improve SINR of MUE?s and SUE?s uplink
connections.
