Abstract
LTE radijsko sučelje je dizajnirano kako bi omogućilo veće informacijske brzine, nisku latenciju i radijski pristup optimiziran za paketske aplikacije. Napredne višeantenske tehnike su važan segment radijskog sučelja i nužne su za postizanje navedenih ciljanih performansi LTE sustava. Rad će prikazati osnovne karakteristike LTE sheme višestrukog pristupa, kao i pregled strukture fizičkog sloja, pripadajućih fizičkih kanala i signala, te kako je fizički sloj pripremljen za primjenu višeantenskih rješenja. Također će obraditi važnije protokole za raspoređivanje resursa, prilagodbu veze i ponovna slanja podataka, koji su potrebni za učinkoviti rad LTE sustava, s potrebnim naznačenim modifikacijama ovih protokola za slučaj višeantenskih konfiguracija. Rad će, osim općeg pregleda različitih višeantenskih tehnika kao što su: prijamni diverziti, odašiljački diverziti, oblikovanje antenskog snopa i prostorno multipleksiranje (MIMO), detaljno specificirati rješenja kakva su implementirana u prvim LTE sustavima. Poseban naglasak bit će na opisu MIMO sheme kao najnaprednijeg oblika višeantenskih sustava. Na kraju će, kroz simulacije na razini mreže, biti uspoređene značajke sustava, kapacitet, pokrivanje i pružena razina usluge za pojedine višeantenske tehnike i različite antenske konfiguracije.
Abstract (english)
LTE radio interface is designed to enable higher data throughput, lower latency and radio access optimized for packet data applications. Advanced multiantenna techniques are an important segment of new radio interface and are necessary to achieve targeted performance of LTE system. This thesis will present basic characteristics of LTE multiple access scheme, as well as overview of physical layer structure, respective physical channels and signals and the preparation of physical layer for application of different multiantenna solutions. Also, important scheduling protocols, link adaptation and retransmission principles are elaborated, which are necessary for efficient functioning of LTE system. Required modifications of these protocols are specified to support multiantenna configurations. In addition to general overview of different multiantenna techniques, including: receive diversity, transmit diversity, beamforming and spatial multiplexing (MIMO), this thesis will specify in detail solutions as implemented in first LTE systems. Special emphasis will be given to description of MIMO scheme as the most advanced form of multiantenna system. Finally, through system level simulations, system performances will be compared in terms of capacity, coverage and offered quality of service for individual multiantenna techniques and different antenna configurations.
