Cell planning for heterogeneous cellular networks
2013 IEEE Wireless Communications and Networking Conference (WCNC), 2013Low-power base stations (BSs), such as pico BSs, femto BSs, and relay nodes, are introduced to the heterogeneous cellular networks to enhance coverage and improve system capacity. Compare with macro BS, low-power BS has much lower transmission power, smaller physical size and lower cost.

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 ...

A Circular Interference Model for Heterogeneous Cellular Networks
IEEE Transactions on Wireless Communications, 2016Scaling up the number of base stations per unit area and augmenting the heterogeneity of networks are two major trends in mobile cellular systems of the fourth (4G)- and fifth generation (5G), making it increasingly difficult to characterize aggregate interference statistics with system models that are characterized by a low number of parameters.

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 ...

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
