1. Improving the Energy Efficiency of Cellular IoT Device
Sammanfattning : Cellular Internet of Things (CIoT) has emerged as a promising technology to support applications that generate infrequent data. One requirement on these applications, often battery-powered devices, is low energy consumption to enable extended battery life. LÄS MER
2. Integrated Access and Backhaul for 5G and Beyond (6G)
Sammanfattning : 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. LÄS MER
3. On Adjacent Channel Interference-Aware Radio Resource Management for Vehicle-to-Vehicle Communication
Sammanfattning : Safety applications play an essential role in supporting traffic safety and efficiency in next generation vehicular networks. Typical safety applications require vehicle-to-vehicle (V2V) communication with high reliability and low latency. LÄS MER
4. Improved Techniques for Retransmission and Relaying in Wireless Systems
Sammanfattning : The last three decades have seen significant advances in the wireless communication field. As the data rates of wireless systems are increasing, the demand for mobile services also is increasing rapidly. Like other natural resources, radio spectrum suitable for mobile wireless communications is also limited. LÄS MER
5. HARQ Systems: Resource Allocation, Feedback Error Protection, and Bits-to-Symbol Mappings
Sammanfattning : Reliability of data transmission is a fundamental problem in wireless communications. Fading in wireless channels causes the signal strength to vary at the receiver and this results in loss of data packets. To improve the reliability, automatic repeat request (ARQ) schemes were introduced. LÄS MER
