The antenna configurations are illustrated in Figure 12-19. 12.10.3 Mobility In order to evaluate the 3GPP LTE-Advanced candidate against the mobility requirement, the meth- odology that is set out in reference [6] is followed, where in the first step the system-level simulation is performed for each test environment in the uplink to obtain the uplink SINR distribution (see Figure 12-20). From the uplink SINR distribution the 50% point of the CDF is obtained for each test CHAPTER 12 Performance of IEEE 802. 16m and 3GPP LTE-Advanced TABLE 12-20 3GPP LTE VolP Capacity [13] VolP Capacity Antenna Duplex ITU-R (Active Users/MHz/ Configuration Scheme Environment Requirement Cell) Antenna configuration (A) Antenna configuration (C) Antenna configuration (A) Antenna configuration (C) environment. In the second step, link-level simulation is conducted to generate the spectral efficiency versus SINR curves for each test environment. The spectral efficiency values include the effect of the control channel overhead from the uplink system-level simulations for each test scenario. The mobility requirement is met, if the spectral efficiency values from the link-level curves, obtained for the median SINR value from the system-level simulations, are greater than the ITU-R targets. These values were obtained assuming different antenna configurations in the uplink, as shown in Table 12-21. It can be concluded from Table 12-21 that any of the evaluated 3GPP LTE configurations can fulfill the ITU-R requirements concerning mobility for all test environments. 12.10.4 Peak Spectral Efficiency The peak spectral efficiency of 3GPP LTE-Advanced is calculated assuming 20 MHz bandwidth, one OFDM symbol for downlink control signaling, cell-specific reference signals corresponding to one and four cell-specific antenna ports, UE-specific reference signals corresponding to 24 and zero resource elements per resource-block pair, and physical broadcast channel and synchronization se
