   Author : Charitha Madapatha Madapathage Don; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stochastic geometry; Node selection; Beyond 5G; Backhaul; 6G; Blockage; Coverage probability; Poisson point process PPP ; Integrated access and backhaul IAB ; Relay; Constrained deployment; 5G new radio NR ; Tree foliage; Millimeter wave mmWave communications; Densification; 3GPP; Wireless backhaul; Routing; Genetic algorithm GA ; Topology optimization;

   Abstract : Enabling network densification to support coverage-limited millimeter wave (mmWave) frequencies is one of the main requirements for 5G and beyond. It is challenging to connect a high number of base stations (BSs) to the core network via a transport network. READ MORE

4. 2. Towards Context Information-based High-Performing Connectivity in Internet of Vehicle Communications

   Author : Hao Guo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporal correlation; relay; Internet-of-vehicles IoV ; reconfigurable intelligent surface; throughput; wireless backhaul; outage probability; channel state information CSI ; 5G B5G; spatial correlation; rate adaptation; mobile relay; 6G; vehicle-to-everything V2X ; Marcum Q-function; integrated access and backhaul IAB ; predictor antenna; blockage; millimeter wave;

   Abstract : Internet-of-vehicles (IoV) is one of the most important use cases in the fifth generation (5G) of wireless networks and beyond. Here, IoV communications refer to two types of scenarios: serving the in-vehicle users with moving relays (MRs); and supporting vehicle-to-everything (V2X) communications for, e.g., connected vehicle functionalities.

5. 3. Predictor Antenna Systems: Exploiting Channel State Information for Vehicle Communications

   Author : Hao Guo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 6G; Beyond 5G; temporal correlation; spatial correlation; wireless backhaul; outage probability; hybrid automatic repeat request HARQ ; channel state information CSI ; throughput; integrated access and backhaul IAB ; mobile relay; predictor antenna PA ; mobility; Marcum Q-function; relay; rate adaptation;

   Abstract : Vehicle communication is one of the most important use cases in the fifth generation of wireless networks (5G).  The growing demand for quality of service (QoS) characterized by performance metrics, such as spectrum efficiency, peak data rate, and outage probability, is mainly limited by inaccurate prediction/estimation of channel state information (CSI) of the rapidly changing environment around moving vehicles.
