7 PR-TN 2009/ Introduction This report concludes the work carried out under SLA for NXP under the title Tracking and Analysis of 3GPP Standards during 2007 and The project focused on the physical and protocol layers of the radio access network standardisation for UMTS, HSPA and LTE. The key outputs comprised transfer of knowledge and expertise to the NXP development teams, and, from August to November 2008, to ST-NXP Wireless. This report provides an overview of the status of the standardisation work in 3GPP and an outline for its continuation, as well as detailing the contributions made by the project to 3GPP and NXP/ST-NXP during the period of the SLA. 7

8 PR-TN 2009/ GPP Roadmap and Status Standardisation in 3GPP is proceeding in two parallel tracks: evolution of the original UMTS WCDMA air interface, and the development of LTE. Within each track, each specification release is fully backward-compatible, but the transition from the WCDMA air interface to LTE is non-backward-compatible, requiring multi-mode terminals and independent network infrastructure. This is illustrated in Figure 1. UMTS Release 99 HSDPA HSUPA Release 7 HSPA+ LTE LTE-A Rel-8 Rel-9 Rel-10 Figure 1: Standardisation tracks in 3GPP From Release 8 onwards, the specification releases are linked between HSPA and LTE. Thus the first release of LTE is Release 8. The approximate timescales of each release, together with typical or projected deployment dates, are shown in Figure 2. Figure 2: Approximate timelines for each 3GPP specification release 8

9 PR-TN 2009/ HSPA Evolution HSPA evolution, otherwise known as HSPA+, provides a smooth upgrade path for operators who have already invested in WCDMA networks. Three general trends can be observed in HSPA evolution: 1. Support for packet-switched services, especially based on IP, with improved terminal battery life through discontinuous transmission and reception; 2. Support for higher data rates through the use of wider bandwidths (multiple 5MHz carriers) with wide area coverage; 3. Support for higher peak data rates through higher spectral efficiency (MIMO and higher-order modulation), generally achievable only in small coverage areas. The strongest support for the HSPA evolution track comes from Qualcomm, Ericsson, Nokia/NSN, Samsung, Huawei. The interested operators are Vodafone and Orange. Other companies showing some interest are Motorola, Alcatel-Lucent, InterDigital, LG and NEC, as well as Chinese companies (CATT, ZTE, TDTech) for TD-SCDMA evolution. The key features of each release of WCDMA/HSPA can be summarised as follows: Release 99: Introduction of the WCDMA air interface, fulfilling IMT2000 requirements for a 3 rd Generation system. FDD and TDD modes provided, within a 5MHz carrier bandwidth. Release 4: Narrowband TDD mode added, otherwise known as TD-SCDMA Release 5: High-Speed Downlink Packet Access (HSDPA) Release 6: High-Speed Uplink Packet Access (HSUPA) Fractional Dedicated Channel (F-DPCH) Multimedia Broadcast / Multicast Service (MBMS) Release 7: Enhanced Layer 2 support for high data rates MIMO for HSDPA 9

11 PR-TN 2009/ LTE LTE is a non-backward-compatible revolution, covering both the air interface and the radio access network architecture. It is accompanied by a major development of the nonradio aspects, including the core network, under the term System Architecture Evolution (SAE). Together, LTE and SAE comprise the Evolved Packet System (EPS), in which both the core network and the radio access are fully packet-switched. LTE is not 4G, but it paves the way towards 4G. The peak data rate targets for LTE are 100Mbps downlink / 50Mbps uplink, with 2 to 4 times the spectral efficiency (bps/hz) of UMTS Rel-6. Substantial effort has also been devoted towards providing uniform service provision and improved cell-edge performance, which are key goals for network operators to differentiate their service provision from hot-spot technologies like WiFi and WiMAX. Reduced end-to-end latency has also been a priority in the development of LTE, in order to support new applications like multi-user interactive gaming. LTE also features flexible use of spectrum allocations, with fully scalable bandwidth up to 20MHz (e.g. supporting deployment in 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz or 20MHz carrier bandwidths). All terminals are required to support at least 20MHz bandwidth (receive and transmit). Early deployments are likely to be around 2.6GHz (Europe) and 700MHz (USA), as well as in due course reusing existing UMTS and GSM spectrum (beginning with 900MHz in Europe). Strong pressure was exerted for a common design for LTE for operation in paired and unpaired spectrum, and although the FDD and TDD structures are separate, the differences between them are small and almost entirely confined to the physical layer. A common platform to implement both modes makes sense in LTE. In the air interface, LTE makes use of some key new technology components: Multicarrier technology LTE moves away from the CDMA air interface of WCDMA. Orthogonal Frequency- Division Multiple Access (OFDMA) was selected for the LTE downlink, while a related scheme, known as Single-Carrier Frequency-Division Multiple Access (SC-FDMA) was chosen for the uplink. OFDM subdivides the bandwidth available for signal transmission into a multitude of narrowband subcarriers, arranged to be mutually orthogonal, which either individually or in groups can carry independent information streams; in OFDMA, this subdivision of the available bandwidth is exploited by sharing the subcarriers between multiple users. This resulting flexibility can be used in various ways: Different spectrum bandwidths can be utilized without changing the fundamental system parameters or equipment design; Transmission resources of variable bandwidth can be allocated to different users and scheduled freely in the frequency domain; 11

12 PR-TN 2009/00177 Fractional frequency re-use and interference coordination between cells are facilitated. OFDM is robust against time-dispersive radio channels, thanks to the subdivision of the wideband transmitted signal into multiple narrowband subcarriers, enabling inter-symbol interference to be largely constrained within a guard interval at the beginning of each symbol. Low-complexity receivers can be designed for the mobile terminal, by exploiting frequency-domain equalization. By contrast, the transmitter design for OFDM is relatively costly, as the Peak-to-Average Power Ratio (PAPR) of an OFDM signal is high, resulting in a need for a highly-linear RF power amplifier. However, this limitation is not inconsistent with the use of OFDM for the downlink, as low-cost implementation has a lower priority for the base station than for the mobile terminal. In the uplink, however, the high PAPR of OFDM is difficult to tolerate for the transmitter of the mobile terminal, since it is necessary to compromise between the output power required for good outdoor coverage, the power consumption, and the cost of the power amplifier. SC-FDMA provides a multiple access technology which has much in common with OFDMA in particular the flexibility in the frequency domain and the incorporation of a guard interval at the start of each transmitted symbol to facilitate low-complexity frequency-domain equalization at the receiver. At the same time, SC-FDMA has a significantly lower PAPR. It therefore enables the uplink to benefit from the advantages of multicarrier technology while avoiding excessive cost for the mobile terminal transmitter and retaining a reasonable degree of commonality between uplink and downlink technologies Multiple antenna technology The use of multiple antenna technology allows the the spatial domain to be exploited, giving another degree of freedom and the potential for additional capacity. This becomes essential in the quest for higher spectral efficiencies. The use of multiple antennas leads to the theoretically-achievable spectral efficiency being scaled linearly with the minimum of the number of transmit and receive antennas employed, at least in suitable radio propagation environments. Multiple antennas can be used in a variety of ways, mainly based on three fundamental principles: Diversity gain: Use of the space-diversity provided by the multiple antennas to improve the robustness of the transmission against multipath fading. Array gain: Concentration of energy in one or more given directions via precoding or beamforming. Spatial multiplexing gain: Transmission of multiple signal streams to a single user on multiple spatial layers created by combinations of the available antennas. 12

13 PR-TN 2009/00177 The LTE system includes several complementary multiple-antenna options which allow for adaptability according to the deployment and the propagation conditions of the different users Packet-Switched Radio Interface LTE is designed as a completely packet-oriented multiservice system, without the reliance on circuit-switched connection-oriented protocols prevalent in GSM and the first releases of WCDMA. In LTE, this philosophy is applied across all the layers of the protocol stack. LTE therefore uses a transmission time interval (TTI) of just 1ms, allowing very low latency to be achieved Flat Network Architecture LTE moves away from the hierarchical radio access network architecture of WCDMA (with separate base stations (NodeBs) and radio network controllers (RNCs)) to a flat network of interconnected base stations controlling the entire radio resource management (RRM) functionality, known as enodebs References For further information on LTE, the reader is referred to the 36.xxx series of specifications available from and to the following books: LTE The UMTS Long Term Evolution: From Theory to Practice Edited by: Stefania Sesia, Issam Toufik, Matthew Baker Hardback, 648 pages Wiley, February 2009 ISBN: Available from Where this book is exceptional is that the reader will not just learn how LTE works but why it works from Foreword by Adrian Scrase, ETSI Vice- President, International Partnership Projects. 13

The further development of LTE will proceed first with Release 9, consisting of a set of relatively minor enhancements, without exceeding the 20MHz carrier bandwidth. Release 9 is likely to be comprised predominantly of features initially considered for Release 8, but not prioritised and therefore not finally included in Release 8. Examples are MBMS Single Frequency Network operation, and multi-layer beamforming. Release 10 will be a much more major enhancement of LTE, known as LTE-Advanced, or simply LTE-A. LTE-A will extend the capabilities of LTE to exceed the IMT- Advanced requirements. This targets peak data rates of 1Gbps downlink / 500Mbps uplink for low mobility scenarios. Likely features of LTE-A include: Spectrum aggregation, enabling up to 100MHz to be used in a single link (either contiguous or non-contiguous, but in any case comprised of separate 20MHz carriers). Downlink MIMO extensions to 8x8 antenna configurations. Uplink MIMO with up to 4x4 antenna configurations. Co-operative MIMO transmissions from multiple cells. 14

15 PR-TN 2009/00177 Uplink multiple access scheme enhancement to allow the use of non-contiguous blocks of subcarriers (so-called Clustered DFT-S-OFDM ). Use of Relay Nodes to extend coverage (with the Relay Nodes probably appearing like normal base stations but with an in-band LTE interface to one or more neighbouring base stations). 15
