Energy Efficiency of Heterogeneous Cellular Network
2010 IEEE 72nd Vehicular Technology Conference - Fall, 2010The growing energy consumption driven by dramatic increases in the number of users and data usage becomes the key issue for operators in meeting demands on cost reduction and environmental impact targets. Deployment of low power base stations or relay stations in traditional macro cells is expected to reduce the total energy consumption of cellular ...

Backhauling in Heterogeneous Cellular Networks: Modeling and Tradeoffs
IEEE Transactions on Wireless Communications, 2015Consumer demand for data has increased tremendously over the last years, and small cell networks are increasingly being considered as one of the key technologies to cope with this demand. Small cell network deployments within the conventional macro cellular networks are creating a significant amount of heterogeneity compared to traditional cellular ...

Heterogeneous partial feedback design in heterogeneous OFDMA cellular networks
2012 IEEE International Conference on Communications (ICC), 2012Modern heterogeneous networks have an inherent heterogeneous structure such as user densities and large scale channel effects that motivates this work on heterogeneous partial feedback design. In this paper, we address the partial feedback design issue in an OFDMA-based macro-pico cellular system employing the best-M partial feedback strategy.

Delay and Reliability Tradeoffs in Heterogeneous Cellular Networks
IEEE Transactions on Wireless Communications, 2016Network densification is one of the dominant evolutions to increase network capacity toward future cellular networks. However, the complex and random interference in the resultant interference-limited heterogeneous cellular networks (HCN) may deteriorate packet transmission reliability and increase transmission delay, which are essential performance ...

Power control and clustering in heterogeneous cellular networks
Wireless Networks, 2016Recently, it is widely believed that significant coverage and performance improvement can be achieved through the deployment of small cells in conjunction with the well-established macro cells. However, it is expected that the high density of base stations in such heterogeneous cellular networks will give rise to multiple design problems related to ...

Downlink Synchronization Techniques for Heterogeneous Cellular Networks
IEEE Transactions on Communications, 2015Base stations (BS) in a cellular network send unique synchronization signals based on their physical layer cell-identity, in every frame. To synchronize with a BS, a mobile terminal (MT) needs to identify the following synchronization parameters—starting time of the frame, relative frequency offset and the cell-identity of the corresponding BS.

An improved algorithm for transmission in heterogeneous cellular networks
2017 Twelfth International Conference on Digital Information Management (ICDIM), 2017This paper presents improvements to a coverage algorithm that we previously proposed for use in heterogeneous cellular networks, with the improved algorithm being referred to as the modified coverage algorithm. The modified coverage algorithm maintains the coverage advantages provided by the previous coverage algorithm; that is, users can be covered by

Network Modeling in Heterogeneous and Cooperative Cellular Communications.
2016The rapid increase in use of smart phones and devices has introduced a growing demand in data traffic which the conventional homogeneous macro cells can no longer satisfy. A promising solution to this is by spectrum reuse through deploying various low-power small cells overlaid on the macro cell.
