The fifth generation (5G) mobile networks are envisioned to support the deluge of data traffic
with reduced energy consumption and improved quality of service (QoS) provision. To this …

In multi-tier cellular networks, user performance in both the downlink (DL) and uplink (UL)
transmissions depend on the transmit powers of the base stations (BSs) in different network …

With device-to-device (D2D) communications, a user terminal can be used as a relay node
to support multi-hop transmission, so that cell-edge or deeply faded users can obtain a …

In this paper, we model and analyze the downlink (DL) wireless power transfer and uplink
(UL) information transmission of K-tier heterogeneous cellular networks (HCNs) with …

Multi-tier cellular networks are a cost-effective solution for capacity enhancement in urban
scenarios. In these networks, effective mobility strategies are required to assign users to the …

Device-to-device (D2D) communication underlaying cellular networks will become an
important technology in the future networks such as International Mobile …

O-RAN is currently emerging as the way to build a virtualized 5G and beyond Radio Access
Network (RAN) that is based on open interfaces and off-the-shelf hardware. O-RAN …

In this paper, we propose a load-aware and QoS-aware user association strategy that jointly
considers the load of each BS and user's achievable rate instead of only utilizing the latter …

As one of the key technologies of 5G wireless communication technology, cooperative multi-
access edge computing allows one device to associate multiple edge nodes simultaneously …

This paper addresses a joint downlink and uplink aware cell association problem in a multi-
tier heterogeneous network in which base stations (BSs) have finite number of resource …
