The present document captures evaluation results and analysis from the study item on "Uplink MIMO for HSPA" described in [2]. The work under this study intends to capture the feasibility and merits of UL MIMO in terms of average user throughput for the following configuration

• Up to 2 streams can be transmitted by the UE
• UL MIMO transmission applies to E-DCH physical channels
• Both 2x2 and 2x4 configurations are considered

Additionally, the following are also investigated:

• Impact on infrastructure implementation
• Impact on UE implementation
• Impact on specifications
