    Diverse applications in vehicular network present specific requirements and challenges on wireless access technology. Although considered as the first standard, IEEE 802.11p shows the obvious drawbacks and is still in the field- trial stage. In this paper, we propose long-term evolution (LTE)-V as a systematic and integrated V2X solution based on time-division LTE (TD-LTE) 4G. LTE-V includes two modes: 1) LTE-V-direct and 2) LTE-V-cell. Comparing to IEEE 802.11p, LTE-V-direct is a new decentralized architecture which modifies TD- LTE physical layer and try to keep commonality as possible to provide short range direct communication, low latency, and high reliability improvements. By leveraging the centralized architecture with native features of TD-LTE, LTE-V-cell optimizes radio resource management for better supporting V2I. LTE-V-direct and LTE-V-cell coordinate with each other to provide an integrated V2X solution. Performance simulations based on sufficient scenarios and the prototype system with typical cases are presented. Finally, future works of LTE-V are envisioned.

  • Analyzing and enhancing the resilience of LTE/LTE-A systems to RF spoofing

    The long-term evolution (LTE) is cellular communications standard that is widely adopted and deployed around the world. It offers high-speed wireless services to meet the increasing demand on user data traffic. LTE technology is also considered for public safety networks. Hence, it is mandatory to ensure that the LTE system can operate in interference-prone environments including targeted interference. We introduce the term LTE control channel spoofing, which refers to transmitting a partial LTE downlink frame, created by a fake eNodeB which does not possess the registration keys nor offers any service. We have built a testbed to demonstrate that this can cause permanent denial of service for UEs that are in cell selection process. This is achieved by sending fake control channel messages rather than authentication attacks. The failure of attachment that is caused by LTE control channel spoofing can be explained in conjunction with the 3GPP specifications. Mitigation techniques are proposed to effectively enhance the robustness of LTE systems and ensure that it is secure and available when and where needed. The recommended modifications to the specifications only require simple changes to UE message handling and are backward compatible with currently deployed LTE networks.

  • An Optimized and Distributed Data Packet Forwarding Scheme in LTE/LTE-A Networks

    Long-term evolution (LTE)/LTE-advanced (LTE-A) networks have recently introduced a data packet forwarding scheme between evolved node Bs (eNBs) to reduce the signaling overhead and the delay incurred in the data path switching scheme, which is a baseline handover scheme in LTE/LTE-A networks. Even with the data packet forwarding scheme, if the length of the forwarding chain is set inappropriately, the data packet forwarding scheme suffers from the degraded throughput. To attain the optimal handover performance in terms of throughput and delay and reduce the signaling overhead, we propose an optimized and distributed data packet forwarding scheme where the optimal length of the forwarding chain is obtained by a Markov decision process (MDP). In addition, a low-complexity value iteration algorithm is devised to solve the optimality equation of MDP in a more practical manner. Real trace-driven evaluation results demonstrate that the proposed scheme determines the optimal length of the forwarding chain adaptively to the applications' quality-of- service (QoS) requirements and reduces the signaling overhead and delay while achieving higher throughput in diverse environments.

  • Toward LTE commercial launch and future plan for LTE enhancements (LTE-Advanced)

    As a promising radio access technology for next generation mobile communication systems, LTE (Long-Term Evolution) is being standardized by the 3rd Generation Partnership Project (3GPP) international standardization organization. LTE Release 8 has many advantages to the other systems, e.g., the peak throughput is 300Mbps in Downlink (DL) and 75Mbps in Uplink (UL), 2-3 time higher spectrum efficiency than Rel. 6 HSPA (High Speed Packet Access), very low latency around 5msec in RAN (Radio Access Network) and 100msec for connection setup time. With Release 8, the first version for LTE specification, being completed in March 2009, the LTE standard is now being developed towards commercialization in various countries in the world. This paper addresses the plan for LTE commercial launch in NTT DOCOMO and future plan for LTE Rel. 9 and LTE-Advanced (LTE Rel. 10 and beyond).

  • Voice over LTE (VoLTE)

  • LTE UE Operations Procedures and Anatomy

    Once the user equipment (UE) is powered ON, it triggers the CPU reset and initially it performs the booting and system initialization related tasks including device self‐test. In the modem unit, once the system initialization is over and operating system (OS) is loaded into the memory, then OS takes the control and starts executing different tasks, where different modem sublayers and procedures are running as OS threads. In order to synchronize time and frequency with a UE cell the eNB broadcasts two types of downlink physical signals: a primary synchronization signal (PSS); a secondary synchronization signal (SSS). These two signals were especially designed to enable time and frequency synchronization. They also indicate physical layer cell identity, cyclic prefix length, and frequency division duplex (FDD), or time division duplex (TDD) mode used in the cell.

  • Allocation of Control Resources for Machine-to-Machine and Human-to-Human Communications Over LTE/LTE-A Networks

    The Internet of Things (IoT) paradigm stands for virtually interconnected objects that are identifiable and equipped with sensing, computing, and communication capabilities. Services and applications over the IoT architecture can take benefit of the long-term evolution (LTE)/LTE-Advanced (LTE-A), cellular networks to support machine-type communication (MTC). Moreover, it is paramount that MTC do not affect the services provided for traditional human-type communication (HTC). Although previous studies have evaluated the impact of the number of MTC devices on the quality of service (QoS) provided to HTC users, none have considered the joint effect of allocation of control resources and the LTE random-access (RA) procedure. In this paper, a novel scheme for resource allocation on the packet downlink (DL) control channel (PDCCH) is introduced. This scheme allows PDCCH scheduling algorithms to consider the resources consumed by the random-access procedure on both control and data channels when prioritizing control messages. Three PDCCH scheduling algorithms considering RA-related control messages are proposed. Moreover, the impact of MTC devices on QoS provisioning to HTC traffic is evaluated. Results derived via simulation show that the proposed PDCCH scheduling algorithms can improve the QoS provisioning and that MTC can strongly impact on QoS provisioning for real-time traffic.

  • Challenges of LTE high-speed railway network to coexist with LTE public safety network

    As the speed of train trialled by the French National Rail Corporation has reached more than 500 km/h, the secure and continuous connection to the train control system has only grown more important. In this paper, current status and progress of national disaster safety network project and LTE-based integrated wireless network for railway in Korea, firstly, and the major challenges of LTE-R network to coexist with LTE public safety network are addressed in the aspect of the air interface requirements for the essential railway services. In our view, it is the most important thing at present for designing and planning LTE railway network to eliminate - not to mitigate or reduce - the radio interference, especially from the adjacent LTE public safety network to LTE-based wireless train control because they use the same frequency band.

  • Performance of LTE and LTE‐Advanced

    This chapter begins by examining the peak data rate of an LTE mobile, and reviews the issue that might prevent it from reaching that data rate. It discusses the techniques used for link budget estimation and propagation modelling in LTE and uses the results to estimate the coverage of an LTE cell. The chapter develops the techniques to produce an initial estimate of the capacity of an LTE cell and compares this with more robust estimates that are obtained from simulations. It concludes by examining the typical data rates and cell capacities for voice over IP.
