Resource allocation is a fundamental and vital issue for arbitrary wireless networks, which
can guarantee the network to run efficiently and stably. Especially, in the 5G and future 6G …

In this paper, we consider the problem of resource allocation in a dense small-cell network.
Each small-cell base station is powered by a renewable energy source and operates in the …

In this paper, we propose to re-engineer the wireless backhaul two-tier heterogeneous
networks architecture by developing a novel cooperative transmission scheme based on …

This paper studies the joint design of downlink transmit beamforming and power allocation
in two-tier wireless backhaul small cell heterogeneous networks. We consider reverse time …

This letter investigates joint power control and user clustering for downlink nonorthogonal
multiple access systems. Our aim is to minimize the total power consumption by taking into …

In this paper, we consider a novel model of two-tier wireless backhaul (WB) small cell
networks where each small cell access point is equipped with a buffer of finite storage. We …

This paper considers the downlink transmission of cloud-radio access networks with limited
fronthaul capacity constraint. Unlike the existing approaches where power of fronthaul is a …

We study the downlink of a limited fronthaul capacity cloud-radio access networks (C-RANs).
Three energy efficiency metrics, namely, global energy efficiency (GEE), weighted sum …

In this paper, we develop beamforming (BF) schemes to minimize the total transmitted power
of both uplink (UL) and downlink (DL) in two-tier network with in-band wireless backhaul …

This paper considers the downlink transmission of cloud-radio access networks (C-RANs)
with limited fronthaul capacity. We formulate a joint design of remote radio head (RRH) …
