Abstract [en]

Cellular network expansion in rural areas has been traditionally slower than in dense urban areas. Area coverage in rural areas is fundamentally limited by the deployment cost for the operator. The 5th generation new radio (5G NR) network is designed to deliver unprecedented levels of capacity, high data rates, low latency and high reliability anytime and anywhere. The focus of 5G NR development is on relatively short-range communication using high frequency bands (e.g. mmWave-length) where lots of spectrum is available. For extremely long-range communication (e.g. in rural areas) high frequency bands are less suitable due to the high signal attenuation. One way to increase coverage in rural areas is to allow end users to deploy their own personal local hot-spot nodes that connect to the cellular network. A personal rural hot-spot can make use of higher transmission power and have better antennas than what normal user terminals can be equipped with. This thesis work will study the impacts of ”user deployed rural hot-spots” on the network like how much the network energy consumption can be decreased, what is the effect of discontinuation transmission (DTX) on network sleep mode and how inter site distance (ISD) can be increased to increase the coverage.

One way to increase rural coverage by using the user deployed hot-spot is to reduce the network energy consumption for network operators and results show that by using user deployed hot-spots (enhanced UE) decreased the network energy consumption and while enhancing the BS configuration will require additional capital expense (CAPEX) investment for the network operators. User deployed hot-spot provide better connectivity for the users that are lying in network edges and helps to increase the inter site distance (ISD) of wireless networks.
