Performance of MIMO and 64QAM Application in HSPA+ System

Abstract:

High speed packet access (HSPA) was introduced as the evolution of WCDMA system in 3GPP Rel 5 and 6 for downlink and for uplink. Moreover, HSPA+ Rel 7 makes WCDMA more competitive which adopted multi-input multi-output (MIMO) to support two blocks of data in a TTI and 64QAM for modulation to increase the peak rate. In HSPA+ Rel 8, combination of MIMO and 64QAM can further enhance the data rate in the good channel condition. Theoretically, the terminal can support the maximum downlink data rate of about 42Mbps.
