which the cells should be synchronized within a few micro-seconds. For MBSFN transmission, the samesignal is transmitted from a cluster of neighboring cells so that the energy in each subcarrier from differentcells participating in the MBSFN operation is naturally combined over-the-air. Further for SFN operation,the CP duration should be long enough compared to the time difference between the signals receivedfrom multiple cells. As such, the MBSFN subframes use extended cyclic prefix shown in Table C.2. The7.5 kHz subcarrier spacing using 33 µs CP duration is only applicable for standalone E-MBMS operationusing a dedicated carrier.The MBSFN and unicast traffic (DL-SCH) can also be multiplexed in a TDM fashion on a subframe basiswith the MBSFN subframes preferably using an extended CP duration of 16.5 µs. The reference signalstructure for MBSFN subframe is shown in Figure C.18. In this structure, only the first reference signal ispresent for unicast transmission.Unicast Reference SignalMBMS Reference SignalFigure C.18. Reference Signal Structure for Mixed Carrier MBSFN. 193C.2.2.1.7LTE DL PERFORMANCE WITH SINGLE INPUT MULTIPLE OUTPUT (SIMO)3GPP evaluated LTE downlink performance and finalized results in May 2007. DL peak data rates for 20MHz of spectrum allocation provide the following results:• 61.2 Mbps with 16QAM and 2 layer transmission• 150.8 Mbps with 64QAM and 2 layer transmissionDownlink user throughput results are presented in Figure C.19 and spectrum efficiency results in FigureC.20. These results assume one TX antenna at the BTS and two receive antennas at the UE. The resultsshown are defined by 3GPP as case three, which assumes a 2 GHz carrier center frequency, 1732 minter-site distance, 10 MHz BW, 3 km/h fading and a full queue traffic model. Non-ideal channelestimation is assumed, and the average CQI per RB is reported every 5 ms with a 2 ms delay. Localizedallocation (using frequency selective scheduling) is simulated. Cell edge user throughput corresponds tothe lowest five percentile user throughput.193 Physical Channels and Modulation. 3GPP TS 36.211.www.3GAmericas.org February 2010 Page 170
