Capacity growth of heterogeneous cellular networks
Bell Labs Technical Journal, 2013Heterogeneous cellular networks are composed of a mixture of macro and small (pico) cells embedded in the macro network. We assume uniform traffic for simplicity, and study the scaling of area spectral efficiencies (ASEs) as pico densities are increased, optimizing over transmit power and cell association bias.

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 ...

Scheduling in heterogeneous cellular networks with mobility
2012 Information Theory and Applications Workshop, 2012We examine the scheduling problem in the context of heterogeneous cellular networks in the presence of mobility. We demonstrate that the QoS for users in a cellular network can be optimized using an interference-aware approach that is most effective at low Doppler frequency scenarios or a channel-aware approach that is most effective at higher low ...

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.

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 ...
