Table 12-29 shows the downlink/uplink cell and cell edge spectral efficiency results under the 3GPP case 1 configuration for FDD and TDD modes. The results suggest that, if 3GPP LTE Rel-8 is extended with MU-MIMO 4 X 2 in the downlink, the 3GPP Rel-10 targets can be fulfilled. The table also includes the advanced features by which the performance can be further improved. The uplink performance results indicate that the 3GPP LTE Rel-8 SIMO and 3GPP LTE-Advanced CoMP, SU-MIMO and MU-MIMO schemes can fulfill the 3GPP Rel-10 requirements. In the 3GPP case 1 scenario, the center frequency is 2.0 GHz, the transmission bandwidth is 2 X 10 MHz for the FDD mode and 20 MHz for the TDD mode, inter- site distance is 500 m, the path loss is 20 dB, and all users are assumed to be moving at 3 km/h.
