Although reconfigurable intelligent surface (RIS) technology has manifested great potentials
in improving wireless network's power saving, most existing literature restricts to pure …

The fundamental challenge of the millimeter-wave (mmWave) frequency band is the
sensitivity of the radio channel to blockages, which gives rise to unstable connectivity and …

This paper studies the energy efficiency and sum rate tradeoff for coordinated beamforming
in multicell multiuser multigroup multicast multiple-input single-output systems. We first …

This letter is concerned with joint sub-channel and power allocation in a heterogeneous
network. We consider the uplink of a co-channel framework where a macrocell shares the …

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 …

Downlink beamforming techniques with low beamformer training overhead are proposed for
joint processing (JP) coordinated multipoint transmission (CoMP). The objective is to …

This paper proposes energy-efficient coordinated beamforming strategies for multicell
multiuser multiple-input single-output system. We consider a practical power consumption …

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 …

Beam selection for joint transmission in cell-free massive multi-input multi-output systems
faces the problem of extremely high training overhead and computational complexity. The …

In dynamic time-division-duplexing networks, the available resources per cell can be freely
allocated to either uplink (UL) or downlink (DL) depending on the instantaneous traffic …
