With years of tremendous traffic and energy consumption growth, green radio has been
valued not only for theoretical research interests but also for the operational expenditure …

This paper investigates the joint transmitter and receiver optimization for the energy
efficiency (EE) in orthogonal frequency-division multiple-access (OFDMA) systems. We first …

In energy-harvesting-enabled networks, the intermittent and randomly distributed renewable
energy imposes severe challenges in reliably supplying the time-varying mobile traffic. To …

Multistream carrier aggregation (MSCA) is a promising technique to boost data rates by
enabling users to connect with multiple base stations (BSs) simultaneously. In this paper, we …

In this paper, we study a class of minimum-energy scheduling problems in non-orthogonal
multiple access (NOMA) systems. NOMA is adopted to enable efficient channel utilization …

Most of the existing works on energy-efficient wireless communications only consider the
transmitter (Tx) or the receiver (Rx) side power consumption, but not both. Moreover, the …

Cooperative communications has long been proposed as an effective method for reducing
the energy consumption of the mobile terminals (MTs) in wireless cellular networks …

Due to the advantage of high data rate, low transmission delay and high reliability, the
application of Long Term Evolution for Vehicle (LTE-V) has got more attention on Vehicular …

In this paper, we investigate the energy minimization for the cellular networks with non-
orthogonal multiple access (NOMA). Different from most of existing studies in NOMA …

The rapid pace of innovations in information and communication technology (ICT) industry
over the past decade has greatly improved people's mobile communication experience …
