Utran Long Term Evolution in 3GPP
2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006The 3rd Generation Partner Ship Project (3GPP) produced the first version of WCDMA standard in the end of 1999, which is the basis of the Universal Mobile Telephone System (UMTS) deployed in the field today. This release, called release 99, contained all the basic elements to meet the requirements for IMT-2000 technologies.

Evaluation of signaling loads in 3GPP networks
IEEE Wireless Communications, 20083GPP Release 5 is the first step toward an all-IP cellular network. While Release 99 is still heavily based on a core network inherited from 2G networks, Release 5 introduces a new core network architecture based on IETF protocols. In particular, SIP is used for initiating, managing, and terminating media sessions. However, the use of SIP can result in

Robust Synchronization for 3GPP LTE System
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010This paper addresses problems related to time and frequency synchronization as well as blind CP (cyclic prefix) type identification in 3GPP LTE system. We start with a general framework based on maximum likelihood (ML) parameter estimation. Then, simplified practical algorithms for estimating time and frequency offset as well as blind CP length are ...

3GPP LTE Downlink System Performance
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009In this paper we quantify 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) Release 8 downlink system performance for a macro cell hexagonal grid scenario. The system performance is analyzed for a closed loop Single User Multi-Input Multi Output (SU-MIMO) mode and compared with Single Input Multiple Output (SIMO) and Multi-User (MU ...

Uplink VoIP Support for 3GPP EUTRA
2007 IEEE 65th Vehicular Technology Conference - VTC2007-Spring, 2007Evolved UTRA (EUTRA) is currently under study by 3GPP standards organizations as a long term evolution (LTE) for current generation universal terrestrial radio access (UTRA) networks. One of the key aspects of EUTRA wireless systems will be providing voice services in packet domain using voice over IP (VoIP).

3GPP Release 5 HSDPA Measurements
2006 IEEE 17th International Symposium on Personal, Indoor and Mobile Radio Communications, 2006This paper presents measurement results for 3GPP Release 5 High speed downlink packet access (HSDPA). The results have been obtained in the laboratory and in the field measurements during 2005. The measurements include peak throughput, link adaptation performance, latency, multiuser capacity, mobility and drive test throughput measurements. The results

In this chapter, we illustrate 3GPP modeling for the mobility scenarios in heterogeneous networks. This includes the topology model, user mobility model, handover procedure and modeling of radio link failure and ping-pongs. It is followed by a description of the implementation framework of LTE HetNet simulator which is based on 3GPP modeling ...

A Primer on 3GPP Narrowband Internet of Things
IEEE Communications Magazine, 2017Narrowband Internet of Things (NB-IoT) is a new cellular technology introduced in 3GPP Release 13 for providing wide-area coverage for IoT. This article provides an overview of the air interface of NB-IoT. We describe how NB-IoT addresses key IoT requirements such as deployment flexibility, low device complexity, long battery lifetime, support of ...

Minimization of drive tests solution in 3GPP
IEEE Communications Magazine, 2012Providing network coverage and quality of service (QoS) is an important task of a cellular network operator. This is because cellular spectrum is normally licensed under certain coverage obligations, and operators need to be competitive in market. To improve their networks, operators often send engineers in the field to collect radio measurements, to ...
