1. Investigating and Modeling Uplink Processing in 5G NR Multisector Scheduler Simulator
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : As the latest generation of wireless access technology called Fifth Generation (5G) New Radio (NR) evolves, computational efficiency is key to keep low cost and flexible deployments for vendors. Understanding how the Digital Signal Processing (DSP) load behaves in the digital units is one aspect to enable this efficiency. LÄS MER
2. Optimization of Physical Uplink Resource Allocation in 5G Cellular Network using Monte Carlo Tree Search
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The Physical Uplink Control Channel (PUCCH), which is mainly used to transmit Uplink Control Information (UCI), is a key component to enable the 5G NR system. Compared to LTE, NR specifies a more flexible PUCCH structure to support various applications and use cases. LÄS MER
3. Improved Precision Time Protocol with Relative Clock Phase Information
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : A common time reference among nodes is one of the key requirements in telecommunication, distributed control systems and industrial automation systems. For instance, 3GPP LTE TDD standard requires at least ± 1.5 µsec time accuracy among base stations in order to resolve uplink and downlink transmission. LÄS MER
4. Beamforming in LTE FDD for Multiple Antenna Systems
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : High data rate is still the most crucial factor in cellular systems, and with 5g approaching new techniques are studied to achieve higher bit rates. Using MIMO technology, the spatial domain was exploited through beamforming and multiplexing multiple users’ data together assured more spectrum efficiency which resulted in higher bit rates. LÄS MER
5. Intelligent Beam Weight Computation for Massive Beamforming
Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingSammanfattning : LTE (Long Term Evolution) is likely the most complex wireless system ever developed. It incorporates features that could not have been economically implemented as recently as a decade ago. Today, with large-scale ICs, LTE can be easily accommodated in base stations and battery-powered handsets alike. LÄS MER
