Femtocells, despite their name, pose a potentially large disruption to the carefully planned
cellular networks that now connect a majority of the planet's citizens to the Internet and with …

This paper investigates price-based resource allocation strategies for two-tier femtocell
networks, in which a central macrocell is underlaid with distributed femtocells, all operating …

In this paper, we present a vision beyond the conventional Long Term Evolution Fourth
Generation (LTE-4G) evolution path and suggest that time division duplexing (TDD) could …

In this paper, a decentralized and self-organizing mechanism for small cell networks (such
as micro-, femto-and picocells) is proposed. In particular, an application to the case in which …

The Third-Generation Partnership Project (3GPP) has recently started standardizing the
“licensed-assisted access using LTE” for small cells, which is referred to as dual-band …

In this paper, the problem of uplink user association in small cell networks, which involves
interactions between users, small cell base stations, and macro-cell stations, having often …

We propose a time division duplex (TDD) based network architecture where a macrocell tier
with a “massive” multiple-input multiple-output (MIMO) base station (BS) is overlaid with a …

In this paper, we propose a joint channel allocation and power control algorithm by using
cognitive radio non-orthogonal multiple access (CR-NOMA) for femtocell users (FUs). The …

Femtocells can effectively resolve the poor connectivity issue of indoor cellular users. This
paper investigates the economic incentive for a cellular operator to add femtocell service on …

The concept of femtocell access points underlaying existing communication infrastructure
has recently emerged as a key technology that can significantly improve the coverage and …
