摘要：
Closed loop beamforming transmit diversity is a promising technique to improve the uplink transmission performance in cellular networks. This technique was recently incorporated into the 3GPP HSPA standard. This paper reflects on several design aspects of closed loop beamforming transmit diversity, including: precoded pilot channels design, precoding information determination when UE is in soft handover, and enhanced symmetric beamforming implementation.
