SSCET 2012 - University of New Orleans and IEEE New Orleans Section1010LTEGoal: increase capacity and speed of wireless data networks using new DSP techniques and modulations.Goal: redesign and simplification of the network architecture to an IP-based system with significantly reduced transfer latency compared to 3G architecture. LTE wireless interface is incompatible with 2G and 3G networks, so that it must be operated on a separate wireless spectrumLTE standard finalized in December 2008LTE first publicly available service launched by TeliaSonera in Oslo and Stockholm on December 14, 2009 as a data connection with a USB modem.IP-based network architecture -Evolved Packet Core (EPC)- designed to replace the GPRS Core Network, supports seamless handovers for both voice and data to cell towers with older network technology such as GSM, UMTS and CDMA2000Simplifying the architecture of the system, as it transits from the existing UMTS circuit + packet switching combined network, to an all-IP flat architecture system. E-UTRA is the air interface of LTELTE networks are already providing headline speeds approaching 100 Mbps, but these are only possible under ideal conditions on lightly loaded networks and where user equipment is close to the base station radio antenna.

Downlink:LTE uses OFDM for the downlink (from the base station to the terminal). OFDM uses a large number of narrow sub-carriers for multi-carrier transmission. The basic LTE downlink physical resource can be seen as a time-frequency grid. In the frequency domain, the spacing between the subcarriers, f, is 15kHz. Cyclic prefix is used to maintain orthogonality between the sub-carriers even for a time-dispersive radio channelnormal cyclic prefix of 4.7 sextended cyclic prefix of 16.7 s for highly dispersive environmentsPhysical layer: Data to be transmitted is turbo coded and modulated using QPSK, 16QAM or 64QAM.Followed by OFDMThe OFDM symbols are grouped into resource blocks. Total size of 180 kHz in the frequency domain0.5ms in the time domain. Each 1ms Transmission Time Interval (TTI) consists of two slots (Tslot).Uplink:The LTE uplink transmission scheme for FDD and TDD mode is based on SC-FDMA (Single Carrier-FDMA)OFDM has a very high PAPR. High PAPR requires expensive and inefficient power amplifiers with high requirements on linearity, which increases the cost of the terminal and also drains the battery faster.SC-FDMA with low PAPR also improves coverage and the cell-edge performance.SSCET 2012 - University of New Orleans and IEEE New Orleans Section1818LTE transmission schemeRadio link control (RLC) and medium access control (MAC) layers: responsible for retransmission handling and multiplexing of data flowsLTE includes a two-layered retransmission scheme: fast hybrid-ARQ protocol (in MAC layer) complemented by highly reliable selective-repeat ARQ protocol (in the RLC layer.)Advanced topology networks that optimize pico, micro and femtocellsbring the transmitter closer to the user, to significantly increase data rates and capacitybetter user assignments assigning users to more optimal cells and not always to the strongest. Peak data rates up to 73 Mb/s in the downlink and up to 36 Mb/s in the uplinkPacket-only core network called EPC (Evolved Packet Core) to support IP-based applications and services.SSCET 2012 - University of New Orleans and IEEE New Orleans Section1919LTE Transmission (contd)Transmitted signal organized into sub-frames of 1-ms duration, each consisting of 14 or 12 OFDM symbols, depending on cyclic prefix. Ten sub-frames form a radio frame. Scheduler (in base station) determines, for each 1 ms sub-framewhich users are allowed to transmiton what frequency what data rate to useFading: radio-channel quality varies in time, space, and frequency. LTE can use channel-dependent scheduling in both the time and frequency domain to exploit such variations.SSCET 2012 - University of New Orleans and IEEE New Orleans Section2020LTE SPECTRAL ISSUESDepends on regulatory aspects in different geographical areas,radio spectrum for mobile communication is available in different frequency bands of different sizesuplink and downlink transmissions may be assigned separate frequency bands or must share the same frequency band. different radio-access technologies must be able to operate jointly in the same spectrum bandLTE can be deployed with different bandwidths in order to operate in spectrum of different sizesenable efficient migration of other radio-access technologies to LTEoverall system bandwidth ranging from 1.4 MHz up to 20 MHZLTE provides the possibility for different uplink and downlink bandwidths, enabling asymmetric spectrum utilizationSSCET 2012 - University of New Orleans and IEEE New Orleans Section2121LTE DUPLEXINGBoth FDD and TDDFDD : two carrier frequencies, one for uplink transmission and one for downlink transmission.During each frame, there are ten uplink sub-frames and ten downlink sub-frames; Uplink and downlink transmission can occur simultaneously within a cell. TDD:only a single-carrier frequency,uplink and downlink transmissions are separated in timeto meet requirements on uplink-downlink traffic asymmetries, seven different uplink-downlink configurations are supported in TDDprovisioning of sufficiently large guard periods.

SSCET 2012 - University of New Orleans and IEEE New Orleans Section2323LTE Advanced (lTE-A)SSCET 2012 - University of New Orleans and IEEE New Orleans Section2424LTE ADVANCEDThe evolution of LTE is LTE Advanced, which was standardized in March 2011.3GPP discussing new releases (current is 10)Carrier aggregation: e.g., multiple component carriers of 20 MHz are aggregated to support transmission bandwidths of up to 100 MHz for very high data ratesRelaying to improve coverage and reduce deployment costExtended multi-antenna transmission Coordinated multipoint (CoMP) transmission/reception, where transmission/reception is performed jointly across multiple cell sites to improve cell-edge performance. Satisfy the requirement for peak spectrum efficiency (30 bps/Hz)Low latency and delays[14] Services are expected to commence in 2013.LTEAdvanced - LTE Release10 is set to provide higher bitrates in a cost efficient way and, at the same time, completely fulfil the requirements set by ITU for IMT Advanced, also referred to as 4G.SSCET 2012 - University of New Orleans and IEEE New Orleans Section2525LTE AdvancedIn LTE-Advanced focus is on higher capacity:Increased peak data rate, DL 3 Gbps, UL 1.5 Gbps Higher spectral efficiency, from a maximum of 16bps/Hz in R8 to 30 bps/Hz in R10Increased number of simultaneously active subscribersImproved performance at cell edges, e.g. for DL 2x2 MIMO at least 2.40 bps/Hz/cell.The main new functionalities introduced in LTE-Advanced are Carrier Aggregation (CA), enhanced use of multi-antenna techniques and support for Relay Nodes (RN).

SSCET 2012 - University of New Orleans and IEEE New Orleans Section26Carrier aggregationIncrease in bandwidth in LTE-Advanced is provided through aggregation of R8/R9 carriers. Carrier aggregation can be used for both FDD & TDD.Each aggregated carrier is referred to as a component carrier. The component carrier can have a bandwidth of 1.4, 3, 5, 10, 15 or 20 MHz and a maximum of five component carriers can be aggregated.Maximum bandwidth is 100 MHz. The number of aggregated carriers can be different in DL and UL, however the number of UL component carriers is never larger than the number of DL component carriers. The individual component carriers can also be of different bandwidths

Diminish the effects of fading by transmitting the same information from two different antennas

MIMOSSCET 2012 - University of New Orleans and IEEE New Orleans Section29Able to adjust the type of multi-antenna technique to use according to environment A number of different Transmission Modes (TM) has been definedDL : 9 TMs, where TM1-7 were introduced in Release 8, TM8 was introduced in Release 9 and TM9 was introduced in Release 10. IUL: tM1 and TM2, where TM1 is the default, and it was introduced in Release 8 and TM2 is introduced in Release 10. Through the introduction of TM9 8x8 MIMO is supported DL, and through the introduction of TM2 UL use of 4x4 MIMO UL is enabled.In multi-antenna techniques precoding is used to map the modulation symbols onto the different antennas. Aim is to achieve achieve best possible data reception at the receiver. Precoding depends on:multi-antenna technique usednumber of layers number of antenna portsRelay Nodes

SSCET 2012 - University of New Orleans and IEEE New Orleans Section30Efficient heterogeneous network planning (mix of large and small cells) by introduction of Relay Nodes (RNs). The Relay Nodes are low power base stations that provide enhanced coverage and capacity at cell edges RN can also be used to connect to remote areas without fiber connection.RN is connected to the Donor eNB (DeNB) via a radio interface, Un, which is a modification of the E-UTRAN air interface Uu. Radio resources in Donor Cell are shared between UEs served directly by the DeNB and the Relay Nodes.The RN will to a large extent support the same functionalities as the eNB however the DeNB will be responsible for MME selection.UEs at the edge of the donor cell are connected to the RN via Uu, while UEs closer to the DeNB are directly connected to the DeNB via the Uu interface. Frequencies used on Un and Uu can be different, outband, or the same, inband. In the inband case there is a risk for self interference in the RN.UEs at the edge of the donor cell are connected to the RN via Uu, while UEs closer to the DeNB are directly connected to the DeNB via the Uu interface.
