Energy-Efficient Resource Allocation in Macrocell-Smallcell Heterogeneous Networks

—Cellular users in indoor environments have difficulty to enjoy high rate services supplied only by macro base station (MBS) due to the penetration loss. Smallcell, as a complement to Macrocell, provide the enhanced coverage through constituting heterogeneous network (HetNet) with MSBs. HetNet is an effective candidate for green communications. However, the interference in HetNet is still a ch...

Energy-Efficient Resource Allocation in NOMA Heterogeneous Networks

Non-orthogonal multiple access (NOMA) has attracted much recent attention owing to its capability for improving the system spectral efficiency in wireless communications. Deploying NOMA in heterogeneous network can satisfy users’ explosive data traffic requirements, and NOMA will likely play an important role in the fifth-generation (5G) mobile communication networks. However, NOMA brings new t...

Efficient resource allocation for emerging OFDMA wireless networks

In the context of IEEE 802.16e networks, physical transmission relies on Orthogonal Frequency Division Multiple Access (OFDMA). This mechanism defines resource allocation as a bi-dimensional mapping of spectral resources. Although in the IEEE 802.16e standard the Medium Access Control (MAC) and physical (PHY) layers are well defined, the problem of resource allocation still remains an open issu...

Control and Data Channel Resource Allocation in OFDMA Heterogeneous Networks

This paper investigates the downlink resource allocation problem in Orthogonal Frequency Division Multiple Access (OFDMA) Heterogeneous Networks (HetNets) consisting of macro cells and small cells sharing the same frequency band. Dense deployment of small cells overlaid by a macro layer is considered to be one of the most promising solutions for providing hotspot coverage in future 5G networks....
