Rapporteur:  Mr. Hofmann, Juergen

The rapid globalization of the smart phone market is putting pressure on legacy EDGE networks to improve throughput and spectrum efficiency.
To meet the demands on throughput and spectrum efficiency, MIMO for downlink provides an interesting prospect because it neither puts too high requirements on LTE enabled smart devices nor on legacy EDGE networks. All LTE enabled smart devices come with two receive antennas, which is a valuable radio asset that should be fully utilized. Similarly, legacy EDGE networks are often configured with two transmit antennas to support air combining or transmit diversity.
Performance evaluation submitted to GERAN#54 in GP-120762, to GERAN#55 in GP-121019 and GP-121030 and to GERAN#56 in GP-121248 shows potential of this technique to support significantly higher data peak throughput compared to EGPRS and EGPRS2-A and as well as improving the spectral efficiency.
