Load balancing through proactive offloading users onto small cells is critical for tapping the potential of dense heterogeneous cellular networks (HCNs).

In this work we address the problem of optimal resource allocation in the uplink of a wireless cellular network with Rayleigh fading channels, where the aim is to minimize the average total energy

In this work, we propose and study algorithms for efficient uplink packet-data scheduling in a CDMA cell.

Uplink scheduling in wireless systems is gaining importance due to arising uplink intensive data services (ftp, image uploads etc.), which could be hampered by the currently in-built asymmetry in f

Uplink scheduling in wireless systems is gaining importance due to arising uplink intensive data services (ftp, image uploads etc.

The choice of OFDM-based multi-carrier access techniques for LTE marked a fundamental and farsighted parting from preceding 3GPP networks.

To guarantee the success of massive multiple-input multiple-output (MIMO), one of the main challenges to solve is the efficient management of pilot contamination.

The capacity region of a Multiple Access Channel can be increased by feedback to the sources, since feedback enables cooperative transmission.

Through this paper, the performance of uplink transmissions in terms of latency and reliability in unlicensed spectrum is addressed.
