Texto completoThe evolvement of the uplink in the third generation mobile telecommunication system is an ongoing process. The Enhanced Uplink (EUL) concept is being developed to meet the expected need from more advanced services, like video streaming and mobile broadband. One idea for further improvement in the EUL concept is to introduce Time Division Multiple Access (TDMA), which is studied in this master thesis.
The master thesis assignment is to study the consequences of introducing TDMA in EUL. The goal has been to identify the gains and problems, and how they can be handled. A derived theoretical framework and system simulations, using a radio network simulator, are used.
The overall conclusion is that there is a potentially large gain with an introduction of TDMA in EUL. Simulations in favorable conditions have shown that the system throughput can increase by 100% when there are only User Equipment (UE) that are using EUL in the system and by 50% when there is a mix of speech and EUL UE’s. When using TDMA the uplink load also shows improvements, the mean is generally higher but the variance is generally smaller.
Due to major differences in experienced interference between passive and active UE’s, the signal quality will vary a lot. The big variation in signal quality is identified as the main problem with introducing TDMA in EUL. It is shown that this problem can generate extreme high uplink load, which have a negative impact both on the resource efficiency and the coverage.

Texto completoThe traditional voice service in mobile networks is an important service that mobile users expect high quality from. With the convergence of mobile networks towards an all-IP network, an IP-based speech service becomes important which is referred to as Voice-over-IP (VoIP). The traditional voice service is highly optimized and a VoIP service must therefore fulfil strict quality requirements to provide the same speech service quality. The air interface technology, WCDMA, which is used in third generation communication systems in Europe is constantly developed. An improved concept for the mobile-to-network transmission, called the Enhanced Uplink (EUL) provides for higher uplink capacity for packet data services. It also includes features that may provide a sufficient VoIP service quality in mobile networks, when considering the uplink transmission.
The purpose of this thesis is to evaluate the VoIP capacity over EUL and identify crucial aspects of radio resource management in order to increase the capacity. This is done through dynamic system simulations, using a realistic VoIP traffic model. The VoIP capacity is also estimated by a derived theoretical framework.\newline
It is shown by simulation results and theoretical estimations, that power control is a vital mechanism in order to increase the capacity. Simulation results indicate that a VoIP over EUL capacity of 65\% of the traditional voice service capacity may be reached. The results also indicate that to improve the capacity for larger cells, the allowed VoIP packet delay must be increased.

Texto completoFler och fler människor över hela världen använder ett USB-modem för att ansluta tillInternet. Detta gäller i synnerhet i Sverige, som har den största 3G-täckning i Europa.Jämförbar med fast bredband, med hjälp av ett 3G USB-modemet är en underbar upplevelseför kunden. Allt var som helst vi kan använda vår mobiltelefon är en plats som vi hartillgång till Internet, även om vi färdas i ett tåg, promenad i en park, eller sitter på stranden.Detta gör att arbeta på resande fot mycket enklare. Men kunderna inte vet om nätetgenomströmning, fördröjning, och kostnaden för anslutning passar deras behov. Dessutomfinns det också en fråga om tid att ansluta till nätverket när det inte har funnits några trafikför en tid. Men den genomströmning, fördröjning och "tid för att ansluta" när du använderett modem för att ansluta till ett trådlöst nätverk beror på flera faktorer. I denna avhandlingkommer vi att undersöka dessa faktorer. Mer specifikt avhandlingen analyserar i detaljeffekterna av att använda en USB bifogade nätverkskort, för att få större förståelse för ettsådant gränssnitt nätverk prestanda. Vi har valt att fokusera på upplänk, eftersom detförväntas ha låg kapacitet och det har inte fått lika mycket uppmärksamhet som denerlänkning prestanda.

Texto completoUplink effektstyrning är en funktion för resurshanteringsom styr signalens sändningseffekt från en användaranordning,det vill säga från en mobiltelefon, till ett bas-stationstorn.Det används för att maximera datahastigheterna samtidigtsom den genererade interferensen reduceras.Förstärkningsinlärning är en kraftfull inlärningsteknik.Den har förmågan att inte bara lära en artificiell agent hurman agerar utan också skapa möjligheten för agenten attlära sig själv, genom att samspela med en miljö och samlaegna erfarenheter.I detta examensarbete har vi tillämpat förstärkningsinlärningpå uplink effektstyrning, vilket möjliggör för enintelligent mjukvaruagent att dynamiskt anpassa effektenpå sändningssignalerna hos användarens enheter. Agentenlär sig att hitta lämpliga sändningseffekter för enheternagenom att välja ett värde för korrigeringssignalen med slutenslinga i uplinken. Syftet är att undersöka huruvida förstärkningsinlärningkan förbättra uplink effektstyrningen idet nya 5G-kommunikationssystemet.Problemet formulerades som en Multi-Armed banditförst och utvidgades sedan till en Contextual bandit. Viimplementerade tre olika förstärkningsinlärning algoritmerför agenten att lösa problemet. Utförandet av agenten medanvändning av var och en av de tre algoritmerna utvärderadesgenom att jämföra prestanda för uplink effektstyrningenmed och utan agenten. Med detta tillvägagångssättkunde vi upptäcka om agenten förbättrar prestanda eller inte.Från våra simuleringar upptäcktes att agenten faktisktkan hitta ett värde för korrigeringssignalen som förbättrardatahastigheten, genomflödet mätt i Mbps, av genomsnittligaanslutningar för användarenheterna. Det har däremotockså visat sig att agenten inte har ett betydande bidragavseende interferensstörningarna.
