It provides a brief introduction to LTE including its radio interface architecture, downlink and uplink transmissions, and cell search procedure. Relevant 3GPP specifications for LTE are also listed.
The document discusses the evolution of mobile network architectures from GSM to LTE and SAE. It introduces LTE and SAE, describing them as the radio access network and core network respectively for 3GPP's Evolved Packet System. It provides an overview of the SAE architecture, which includes the Evolved Packet Core and eUTRAN. The core network provides access to external networks and performs functions like QoS, security and mobility management, while the radio access network handles radio interface functions.
This document proposes a concatenated coding scheme with iterative decoding for a bit-shift channel. Specifically, it considers the serial concatenation of an outer error-correcting code and an inner modulation code, possibly preceded by an accumulator. It searches for optimal encoder mappings from an iterative decoding perspective for the inner code, which has been designed to correct single bit-shift errors and have large average power. This is important for inductively coupled channels, as the receiver gets its power from the received signal and the information should maximize the power transferred.
The document proposes LTE Release 10 and beyond (LTE-Advanced) as a candidate radio interface technology for IMT-Advanced. It provides an overview of 3GPP standardization activities, including LTE Release 8 and the work underway in 3GPP to develop LTE-Advanced to meet IMT-Advanced requirements. Key aspects of LTE-Advanced include utilizing carrier aggregation to support wider bandwidth up to 100MHz and advanced MIMO techniques with up to 8-layer transmission to achieve peak data rates of 1Gbps.
The document summarizes radio frequency aspects of 3GPP Release 10 LTE-Advanced technology. Key points discussed include operating bands and transmission bandwidth configurations up to 100MHz supported by carrier aggregation. Feasibility studies covered aspects like UE and base station transmitter/receiver architectures, power levels and emissions for supporting wider channel bandwidths through multiple component carriers. Radio resource management requirements were also addressed to ensure good mobility performance across networks utilizing LTE-Advanced.
This document discusses enhancements to the physical layer of LTE-Advanced (3GPP Release 10). It describes the downlink and uplink physical layer designs, including orthogonal multiple access schemes, reference signals, control signaling, and data transmission methods. It also covers support for time division duplexing, half-duplex frequency division duplexing, and UE categories defined in 3GPP Release 8. The goal of LTE-Advanced is to further improve the LTE standard to meet the requirements of IMT-Advanced.
LTE was developed to meet increasing demands for mobile data by offering significantly higher data rates, lower latency, and improved system capacity compared to HSPA. It transitions to a simplified all-IP architecture. Key LTE technologies include flexible bandwidths up to 20 MHz, OFDMA, MIMO, and channel-dependent scheduling. LTE is expected to provide peak data rates of over 300 Mbps downlink and 75 Mbps uplink for high-end devices.
Mobile broadband growth has led to increased traffic, subscriptions, and revenue for many mobile operators globally. This growth is challenging existing mobile networks and driving operators to evolve their networks to LTE, which can provide significantly higher capacity to support ongoing growth in demand. The mobile industry is largely converging on LTE as the next generation mobile standard, with over 100 operators committed or exploring deployment. LTE promises benefits like lower costs per bit and higher speeds to better meet consumer and business needs in a mobile world.
The document provides an overview of 3GPP Long Term Evolution (LTE) and System Architecture Evolution (SAE). It discusses the motivation for LTE to evolve UMTS towards a packet-only system with higher data rates. The workplan for LTE included feasibility studies from 2004-2006 and standardization work beginning in 2007. Key requirements for LTE included improved peak data rates, latency, spectral efficiency, and reduced infrastructure costs. The LTE air interface uses OFDMA in the downlink and SC-FDMA in the uplink with adaptive modulation up to 64-QAM. Multiple antenna techniques including beamforming, spatial multiplexing, and diversity are supported.
The document proposes LTE Release 10 and beyond (LTE-Advanced) as a candidate radio interface technology for IMT-Advanced. It provides an overview of 3GPP standardization activities, including LTE Release 8 which focused on improving spectral efficiency and reducing latency. LTE-Advanced is being studied to further evolve LTE to meet ITU-R requirements for IMT-Advanced and future needs, with a feasibility study currently ongoing in 3GPP.
This document discusses estimating the performance of concatenated coding schemes. It introduces the Information Processing Characteristic (IPC) which can be used to lower bound the performance of any concatenated coding scheme. The IPC is obtained through asymptotic analysis using EXIT charts or the Approximate Message Passing Convergence Analyzer (AMCA). This provides a lower bound on the IPC that can be achieved with infinite interleaving and iterations. Estimates for realistic schemes with a limited number of iterations are also possible. The IPC can then be used to estimate the resulting bit error ratio.
This document summarizes the key technologies that enable LTE-Advanced, which is an enhancement of LTE to meet the requirements for IMT-Advanced. LTE-Advanced introduces carrier aggregation to support transmission bandwidths up to 100MHz by aggregating multiple LTE carriers. It also enhances multiple antenna technologies to support up to 8 antennas in the downlink and 4 antennas in the uplink. Other technologies introduced include coordinated multipoint transmission and reception, enhanced uplink transmission schemes, and the use of intelligent relay nodes.
