Abstract
Dette speciale undersøger centraliseret radioressourcestyring (RRM) for et relæforstærket LTE-netværk på uplink med fokus på kanaleffekter og interferens fra andre brugerudstyr (UE). Arbejdet omfatter systemniveau-modellering og implementering af et simuleringsmiljø baseret på det MATLAB-baserede RUNE-værktøj, udvidet med modeller for basestationer (BS), relæstationer (RS), UE-fordeling, antenner, termisk støj, fading og sendeeffekt. Uplink fractional power control implementeres, og kanalallokering styres af en centraliseret scheduler baseret på en matrixalgoritme med tidsdomæne proportional-fair (TD-PF) prioritering. Ydelsen vurderes ved at sammenligne scenarier med og uden relæ med hensyn til blandt andet SINR, CQI, gennemstrømning og planlægningsadfærd. Rapporten beskriver simulatorens opbygning, verifikation og analysemetoder; specifikke kvantitative resultater fremgår ikke af det leverede uddrag.
This thesis investigates centralized radio resource management (RRM) for a relay-enhanced LTE network on the uplink, focusing on channel effects and interference from other user equipment (UE). The work includes system-level modeling and the implementation of a simulation environment based on the MATLAB-based RUNE tool, extended with models for base stations (BS), relay stations (RS), UE distribution, antennas, thermal noise, fading, and transmit power. Uplink fractional power control is implemented, and channel allocation is governed by a centralized scheduler using a matrix algorithm with a time-domain proportional-fair (TD-PF) priority metric. Performance is evaluated by comparing relay and non-relay scenarios in terms of SINR, CQI, throughput, and scheduling behavior. The report details the simulator, verification, and analysis methods; specific quantitative findings are not provided in the excerpt.
