The exponential growth in the usage of mobile networks along with the increasing number of User Equipments (UEs) are exacerbating the scarcity of frequency resources. Dense frequency reuse on the downlink of multiuser Orthogonal Frequency Division Multiple Access networks leads to severe Inter-Cell Interference (ICI) problems. Resource and power allocation techniques are required to alleviate t...

The allocation of available resources is one of the main issues in multi-user systems. Dependence of system capacity on radio link quality is an additional obstacle of efficient resource allocation in wireless networks. Combinations of two opposite approaches – fair resource allocation and system capacity maximization are used to solve this problem in practice. This paper proposes a resource al...

This paper presents a joint time-frequency-code-power resource management algorithm based on the Nash bargaining solution in time-division long term evolution systems. First, a joint radio resource allocation scheme at the time, frequency, code and power domain simultaneously is provided for the time-division long term evolution system. Second, the proposed algorithm is modeled as a cooperative...

In this two part paper, we provide a survey of recent and emerging topics in wireless networking. We view the area of wireless networking as dealing with problems of resource allocation so that the various connections that utilise the network achieve their desired performance objectives. In the first part of the paper, we first survey the area by providing a taxonomy of wireless networks as the...

Abstract In DS-CDMA cellular communications systems, the single frequency reuse is utilized and hence large co-channel interference is received from other cells. If the single frequency reuse is not utilized to reduce the other-cell interference, we will face the frequency allocation problem, similar to FDMA systems. In this paper, we divide the available wide frequency band into several narrow...

With the growing demand of radio resources, maximizing spectrum efficiency becomes increasingly important. Traditional static spectrum allocation lacks the mechanisms for sharing the spectral resources between different allocated bands. Hence, spectrum agility which allows the radio devices to dynamically use the idle spectral band is attracting more and more attention. In this paper, we show h...

With the increasing demand of wireless communication and the fact of under utilization of wireless spectrum, a lot of researches have developed technologies to enhance the efficiency of spectrum utilization. The spectrum allocation chart by the Federal Communications Commission (FCC) (NTIA, 2003) indicates high degree legislation of frequency band, in other words, our sky is quite crowded. Howe...

In this paper, we propose a resource allocation and Tx power control scheme, called resource allocation and power control (RAPC) in an LTE-Advanced device-to-device (D2D) network. In the proposed scheme, the macro base station (mBS) and D2D senders (D2DSs) service macro user equipment (mUEs) and D2D receivers (D2DRs) use the different frequency bands and Tx power chosen as D2D links’ locations ...

The overall objective of this paper is to highlight the need to consider a multitude of scenarios for the requirements, design and deployment of mobile broadband networks. The R&D and standardization have for many years been targeting high peak data rates enabled by improved spectral efficiency, adding more spectrum bands, aggregation of frequency bands and offloading to local wireless networks...

For the traditional wireless services, fixed spectrum allocation is the major spectrum allocation methodology. As per this methodology to avoid interference, different wireless services are allocated with different licensed bands. With various emerging wireless technologies, fixed spectrum allocation strategy has resulted scarcity in radio spectrum, due to the fact that most of the available sp...
