CHetNet: crowdsourcing to heterogeneous cellular networks
IEEE Network, 2015Heterogeneous networking (HetNet) is a promising solution to meet the ever increasing demands of wireless applications. However, it is a significant challenge for mobile network operators to deploy HetNet at a large scale. To address this issue, this article discusses a new paradigm in which potential partners are encouraged to participate in ...

Cloud cooperated heterogeneous cellular networks
2013 International Symposium on Intelligent Signal Processing and Communication Systems, 2013This paper introduces a concept of cloud cooperated heterogeneous cellular network (C-HetNet) where small power pico base stations (BSs) overlaid on a macrocell are connected to cloud radio access network (C-RAN) to operate cooperatively with the macro BS.

Analysis of Coverage in Heterogeneous Cellular Networks
IEEE Communications Letters, 2016In this letter, we study the coverage of base stations (BSs) in heterogeneous cellular networks, where BSs with different transmit powers are randomly deployed. Specifically, the boundary of coverage is formulated analytically as the intersection of circles when a multiplicative bias is applied for BS association.

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.

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 ...
