Use of Adaptive Antenna Arrays to Reduce Interference in the E-UTRA Network

Autor: Roman Fokin, Volodymyr Pyliavskyi, S. V. Siden, Dmytro Makoveenko

Publikováno v: 2019 27th National Conference with International Participation (TELECOM).

A computer model for investigating the interference environment in the 4G LTE (E-UTRA) network has been made. The results of modulation of uplink (UL) noise over the use of sectoral antennas of base stations are presented. The technology of power con

Effects of a Phase Rotation Scheme on the DTX Detection Performance for the E-UTRA Uplink ACK/NACK Signals

Autor: Daichi Imamura, Katsuhiko Hiramatsu, Tomohumi Takata, Seigo Nakao

Publikováno v: IEICE Transactions on Communications. :262-272

Hybrid automatic repeat request (HARQ) is employed for the Evolved Universal Terrestrial Radio Access (E-UTRA) downlink. The base station not only decodes the ACK/NACK signals from the user equipment (UE), but also detects a termination of the transm

Performance evaluation of nonsynchronized initial random access for mobile broadband systems

Autor: Ángela Hernández, Antonio Valdovinos, José Ramón Gállego, Israel Guio

Publikováno v: Telecommunication Systems. 43:279-294

In this paper, a comparative analysis of the performance of the nonsynchronized initial random access channel in Mobile WiMAX and E-UTRA systems under different conditions (fast fading, multiuser interference) is carried out. The analysis is focused

A Performance Summary of the Evolved 3G (E-UTRA) for Voice Over Internet and Best Effort Traffic

Autor: Kari Pajukoski, Istvan Z. Kovacs, Jussi Ojala, Markku Kuusela, E. Tuomaala, P. Kinnunen, Mika Rinne

Publikováno v: IEEE Transactions on Vehicular Technology. 58:3661-3673

Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) is a new technology that targets the long-term evolution (LTE) of third generation. The E-UTRA technology has recently been standardized by the Third-Generati

Adaptive CQI Update and Feedback for Codebook Based MU-MIMO in E-UTRA

Autor: Lan Chen, Xiaoming She, Jingxiu Liu, Jianchi Zhu

Publikováno v: IEICE Transactions on Communications. :1546-1552

Codebook based multiple-input multiple-output (MIMO) precoding can significantly improve the system spectral efficiency with limited feedback and has been accepted as one of the most promising techniques for the Evolved UTRA (E-UTRA). Compared with s

A Novel Phase Rotation Scheme on the Constellations for the E-UTRA Uplink ACK/NACK Signals

Autor: Katsuhiko Hiramatsu, Tomohumi Takata, Seigo Nakao, Daichi Imamura

Publikováno v: IEICE Transactions on Communications. :3459-3469

Hybrid automatic repeat request (HARQ) is employed for the Evolved Universal Terrestrial Radio Access (E-UTRA) downlink. The ACK/NACK signals from each user equipment (UE) are multiplexed by code division multiple access (CDMA) and transmitted via a

Field and Indoor Experimental Results of E-UTRA Uplink

Autor: Yoshiaki Ofuji, Sadayuki Abeta, Takehiro Nakamura, Naoto Okubo

Publikováno v: IEICE Transactions on Communications. :1714-1724

This paper investigates the uplink throughput performance and the interference power to other cells using an Evolved UTRA (E-UTRA) laboratory and field experimental system. In E-UTRA uplink, the near-far problem is not an issue since the orthgonality
