Sistem selular hari ini mencapai hadnya untuk kadar data disebabkan oleh jumlah pelanggan yang terus meningkat yang menggunakan perkhidmatan wayarles untuk tujuan perniagaan atau pada masa lapang (kesan telefon pintar). Oleh itu, penyelidikan terkini memberi tumpuan kepada konsep untuk pengurusan gangguan untuk sistem OFDMA selular. Kertas kerja ini membincangkan pelbagai teknik yang berkaitan dengan topik ini, sambil mempertimbangkan konsep dengan kerumitan terendah dan kos backhaul sebagai calon yang menjanjikan untuk digunakan terlebih dahulu. Bermula daripada penerima pembatalan gangguan melalui MIMO berbilang pengguna menggunakan prapengekodan tetap kepada anggaran gangguan berbilang sel, yang meningkatkan ketepatan penyesuaian pautan, kami membincangkan pembentukan pancaran koperasi gelung tertutup menggunakan berbilang stesen pangkalan yang dikumpulkan ke dalam rangkaian teragih wayarles (WDN), yang ditandakan sebagai transmisi sambungan berbilang titik yang diselaraskan dalam penyeragaman 3GPP LTE-Advanced. Jelas sekali, semakin canggih teknik ini, semakin tinggi permintaan untuk maklum balas dan backhaul. Keputusan prestasi disediakan dengan menggunakan simulasi berbilang sel mengikut cadangan daripada 3GPP. Di samping itu, kebolehlaksanaan penghantaran sambungan berbilang titik yang diselaraskan ditunjukkan dalam persediaan prototaip masa nyata, iaitu di Berlin LTE-Advance Testbed.

Abstract: Todays cellular systems reach their limits for data rate due to the continuously increasing amount of subscribers using wireless service for business purposes or in leisure time (smartphone effect). Thus, recent research focuses on concepts for interference management for cellular OFDMA systems. This paper addresses various techniques related to this topic, while considering the concepts with lowest complexity and backhaul costs as promising candidates to be applied first. Starting from interference canceling receivers over multi-user MIMO using fixed precoding to multi-cell interference estimation, which improves the precision of link adaptation, we discuss closed-loop cooperative transmit beamforming using multiple base stations grouped into a wireless distributed network (WDN), which is denoted as coordinated multi-point joint transmission in the 3GPP LTE-Advanced standardization. It is obvious, the more sophisticated these techniques are, the higher the demands for feedback and backhaul become. Performance results are provided by employing multi-cell simulations according to recommendations from 3GPP. In addition, feasibility of coordinated multi-point joint transmission is demonstrated in a real-time prototype setup, i.e. in the Berlin LTE-Advance Testbed.
