Wireless networks are inherently graph-structured, in which, graph representation learning can be utilized to solve complex network optimization problems. In learning, feature vectors for each entity the calculated such that they could capture spatial and temporal dependencies their local global neighborhoods. Specifically, neural (GNNs) powerful tools these problems because of expressive reaso...

Mobile communication systems are not only the core of Information and Communication Technology (ICT) infrastructure but also that our social infrastructure. The 5th generation mobile system (5G) has already started is in use. 5G expected for various use cases industry society. Thus, many companies research institutes now trying to improve performance 5G, is, Enhancement next (Beyond (6G)). 6G m...

Video conferencing has become a popular mode of meeting despite consuming considerable communication resources. Conventional video compression causes resolution reduction under limited bandwidth. Semantic (SVC) maintains high by transmitting some keypoints to represent the motions because background is almost static, and speakers do not change often. However, study on influence transmission err...

Reconfigurable Intelligent Surfaces (RISs) have been recently considered in communication environments for focusing signal reflections to create smart radio environments. As it can favorable propagation conditions by controlling the phase shifts of reflected signals at surface enhance quality. However, current proofs concept require complex operations RIS configuration, which are mainly realize...
