In this paper, new enhanced cognitive radio networks (E-CRNs) based on spectrum sharing
(SS) and spectrum aggregation (SA) are proposed for fifth generation (5G) wireless …

The licensed assisted access (LAA) is the new feature of 3GPP long-term evolution (LTE)
that uses unlicensed spectrum as an additional bandwidth to meet ever-increasing mobile …

The coexistence problem is always a critical issue for wireless communications in
unlicensed bands. The 5G ecosystem involves diversified networks in unlicensed bands …

In order to use Distance Measuring Equipment (DME) properly, the impact of intra-system
and inter-system electromagnetic interference must be analyzed firstly. However, the error of …

Licensed-assisted access (LAA) is a new feature of 3GPP LTE that utilizes unlicensed
spectrum as a means of providing additional bandwidth. For fair coexistence with other …

In this paper, the problem of sub-channel selection for carrier aggregation (CA) systems is
examined. CA enables the achievement of high data rate links via simultaneous …

Recently, 5G has become an important mechanism to serve a growing amount of users in
the network, which provides enhanced mobile broadband (eMBB) and ultra-reliable low …

In this paper, a multiple cluster-based transmission diversity scheme is proposed for
asynchronous joint transmissions (JT) in private networks. The use of multiple clusters or …

Device-to-device (D2D) communication and non-orthogonal multiple access (NOMA) have
been considered promising techniques to improve system throughput. In the NOMA …

In this work, we investigate the capacity allocation problem in the energy harvesting wireless
sensor networks (WSNs) with interference channels. For the fixed topologies of data and …
