Mathematical optimization is now widely regarded as an indispensable modeling and
solution tool for the design of wireless communications systems. While optimization has …

Weighted sum rate maximization (WSRMax) with user specific quality-of-service (QoS)
constraints and general convex transmit power constraints is considered in multi-cell multi …

In this paper, we develop and analyze three limited-feedback resource allocation algorithms
suitable for uplink transmission in heterogeneous wireless networks (HetNets). In this setup …

This paper studies beamforming design problems for multi-cell multi-user downlink networks
with simultaneous wireless information and power transfer (SWIPT). In this system, multi …

We consider a downlink multi-cell multiple-input multiple-output (MIMO) interference
broadcast channel (IBC) using orthogonal frequency division multiplexing (OFDM) with …

In this paper, we propose a series of novel coordination schemes for multi-cell downlink
communication. Starting from full base station (BS) coordination, we first propose a fully …

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

CoMP transmission and reception have been considered in cellular networks for enabling
larger coverage, improved rates, and interference mitigation. To harness the gains of …

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

This article proposes a resource allocation for multi carrier (MC) multiple input single output
(MISO) non-orthogonal multiple access (NOMA) enabling simultaneous wireless information …
