nts for what will officially define "4G" technologies. 3GPP has been holding a series of workshops on the "Systems beyond IMT-2000" since November 2007. The focus of these workshops is specifically on the 3GPP requirements for LTE-Advanced. The key result of these workshops was in the form of a Technical Requirements document that is, TR 36.913 [34]. TR 36.913 was completed in March 2009 and it contains requirements for the further advancements for E-UTRA/E-UTRAN The targets stated in this document either meet or exceed IMT-Advanced requirements. Table 3.12 compares the valued set forth by 3GPP and ITU-R. 3.11.1 Key Non IMT-Advanced Aspects of Rel-10 Rel-10 is in the very early stages of development. Besides focusing on IMT-Advanced, it is also making enhancements to the features that it has inherited from its predecessor Rel-9. Some of the key non 4G features of Rel-10 are as follows [36]: Addressing architectural impacts that result from the introduction of IMS capable Home NodeB and Home eNodeB. Rel-10 is also focusing on the evolution of IMS. 3GPP Evolved Packet System (EPS) Table 3.12 4G targets as set by ITU-R and LTE-Advanced targets by 3GPP Requirements Environment ITU-R Target 3GPP Target Peak Data Rates High Speed/Rural 100 Mbps 100 Mbps Low Speed 1.0 Gbps 1.0 Gbps 1 Gbps (DL), 500 Mbps (UL) Peak Cell Spectral 15 (DL), 6.75 (UL) [Antenna 30 (DL), 15 (UL) [Antenna Efficiency (bps/Hz/cell) Configuration: 4x4 (DL) Configuration: 8x8 (DL) and 2x4 (UL)] and 4x4 (UL)] Average Cell Spectral Case 1 2.4, 2.6, and 3.7 (DL); 1.2 and Efficiency (bps/Hz/cell) Indoor 3.0 (DL), 2.25 (UL) 2.0 (UL) Microcellular 2.6 (DL), 1.8 (UL) Base coverage urban 2.2 (DL), 1.4 (UL) High Speed/Rural 1.1 (DL), 0.7 (UL) Cell edge user Spectral Case 1 0.07, 0.09, and 0.12 (DL); 0.04 Efficiency (bps/Hz/cell) and 0.0 (UL) Indoor 0.1 (DL), 0.07 (UL) Microcellular 0.075 (DL), 0.05 (UL) Base coverage urban 0.06 (DL), 0.03 (UL) High Speed/Rural 0.04 (DL), 0.015 (UL) Scalable Bandwidth up to 40 MHz Not defined yet Latency (control plane) 100 m
