In this regard, 3GPP’s ongoing work on Rel-10 was guided by the LTE-Advanced Study Item work, document TR 36.913, 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; Requirements for Further Advancements for E-UTRA (LTE-Advanced). Additional details on the 3GPP Candidate technology submissions as documented in IMT- ADV/8 may be found in Appendix D of this paper. 113 It is important to note that the 3GPP Rel-10 work which extends the foundation of LTE in Rel-8 and Rel-9 was accepted by the ITU-R as an IMT-Advanced technology under the ITU-R Terminology of “LTE- Advanced.” 114 The positive assessment of the 3GPP LTE technology by the many IMT evaluation groups across the world, now confirmed by the ITU, reinforces the global preeminence of the work of 3GPP which unites the leading mobile technology companies in developing market oriented high performance broadband mobile wireless systems. The 3GPP submission was made jointly in the name of the Partnership’s Organizational Partners: ATIS, ETSI, ARIB, CCSA, TTA and TTC, which represent the North American, European and Asian regions and make 3GPP a truly global initiative. In the final steps of the ITU-R IMT-Advanced process, 3GPP in conjunction with its Organizational Partners will provide the detailed technical specifications and standards to the ITU-R in 2011, for inclusion in the Recommendation ITU-R M. [RSPEC]. The successful candidature of 3GPP LTE as an IMT- Advanced (<strong>4G</strong>) solution builds upon 3GPP’s multi-year continuing success story. By offering a full suite of integrated 3G and <strong>4G</strong> ecosystems for IMT-2000 and now IMT-Advanced, the 3GPP technology family supports the evolving and expanding needs of the broad international base of mobile operators and allows the users of wireless mobile broadband to experience, on a global basis, a rich and innovative range of service and capabilities that is unparalleled by any other technology.

7 STATUS OF RELEASE 10: HSPA+ ENHANCEMENTS AND LTE‐ADVANCED 7.1 LTE‐ADVANCED FEATURES AND TECHNOLOGIES 3GPP LTE Rel-10 and beyond, also known as LTE-Advanced, is intended to meet the diverse requirements of advanced applications that will become common in the wireless marketplace in the foreseeable future. It will also dramatically lower the Capital Expenses (CAPEX) and Operating Expenses (OPEX) of future broadband wireless networks. Moreover, LTE-Advanced will provide for backward compatibility with LTE and will meet or exceed all IMT-Advanced requirements. This section will discuss the enabling technologies of LTE-Advanced Rel-10. The organization of the discussion is as follows: Section 7.1.1 will focus on the support of wider bandwidth. Section 7.1.2 and 7.1.3 will examine uplink and downlink enhancements, respectively. Section 7.1.4 will discuss the support for Relays in the LTE-Advanced network. Section 7.1.5 will detail the support of heterogeneous network. Section 7.1.6 will present MBMS enhancements and Section 7.1.7 will discuss the SON enhancements. Section 7.1.8 will expound on the vocoder rate enhancements. 7.1.1 SUPPORT OF WIDER BANDWIDTH Carrier Aggregation (CA) has been identified as a key technology that will be crucial for LTE-Advanced in meeting IMT-Advanced requirements. The need for CA in LTE-Advanced arises from the requirement to support bandwidths larger than those currently supported in LTE while at the same time ensuring backward compatibility with LTE. Consequently, in order to support bandwidths larger than 20 MHz, two or more component carriers are aggregated together in LTE-Advanced. An LTE-Advanced terminal with reception capability beyond 20 MHz can simultaneously receive transmissions on multiple component carriers. An LTE Rel-8 terminal, on the other hand, can receive transmissions on a single component carrier only, provided that the structure of the component carrier follows the Rel-8 specifications. The spectrum aggregation scenarios can be broadly classified into three categories: 1. Intra-band adjacent 2. Intra-band non-adjacent 3. Inter-band Examples of these scenarios are provided in Figure 7.1. www.4gamericas.org February 2011 Page 51
