Published in 2025 at "IEEE Communications Letters"

DOI: 10.1109/lcomm.2025.3543587

Abstract: The throughput of multicast networks depends not only on the transmission rate, but also on the number of receivers simultaneously served by the transmit signal. In this letter, we develop a cross-layer approach based on… read more here.

Published in 2024 at "IEEE Transactions on Communications"

DOI: 10.1109/tcomm.2025.3541031

Abstract: The main challenges in designing downlink coordinated multicast beamforming in massive multiple-input multiple output (MIMO) cellular networks are the complex computational solutions and significant fronthaul overhead for centralized coordination. This paper proposes a coordinated multicast… read more here.

Published in 2025 at "IEEE Transactions on Vehicular Technology"

DOI: 10.1109/tvt.2024.3463548

Abstract: With the burgeoning demand for data-intensive services, satellite-terrestrial networks (STNs) face increasing backhaul link congestion, deteriorating user quality of service (QoS), and escalating power consumption. Cache-aided STNs are acknowledged as a promising paradigm for accelerating… read more here.
