    • Techniques for transmit power control for multiple antenna transmissions in an uplink are disclosed. A wireless transmit/receive unit (WTRU) generates at least one input stream for transmission and applies a gain factor to each channel. The gain factor is determined based on a reference channel power estimate. The WTRU generates at least two data streams from the input stream for transmission via a plurality of antennas and applies weights to the data streams. The gain factor and/or the weights are controlled such that a transmit power on each antenna is within a maximum allowed value. The WTRU may perform power scaling on a condition that a transmit power on any antenna exceeds the maximum allowed value. The WTRU may scale down an enhanced dedicated channel (E-DCH) dedicated physical data channel (E-DPDCH) first before other channels. For multiple E-DCH streams, the WTRU may calculate an E-DPDCH power offset based on an additional power offset factor due to multiple stream transmission.
    • 公开了用于上行链路中多天线传输的发射功率控制的技术。 无线发射/接收单元(WTRU)生成至少一个用于传输的输入流,并将增益因子应用于每个信道。 基于参考信道功率估计来确定增益因子。 WTRU从输入流生成至少两个数据流,以经由多个天线传输,并对数据流应用权重。 控制增益因子和/或权重,使得每个天线上的发射功率在最大允许值内。 WTRU可以在任何天线上的发射功率超过最大允许值的条件下执行功率缩放。 WTRU可以在其他信道之前首先缩小增强型专用信道(E-DCH)专用物理数据信道(E-DPDCH)。 对于多个E-DCH流,WTRU可以基于由于多流传输而引起的附加功率偏移因子来计算E-DPDCH功率偏移。

    • Embodiments of the invention exploit cyclostationarity of linearly modulated signals, transmitted through fading channels, to provide robust blind and data-aided mobile speed estimators. Embodiments of the invention utilize at least two methods of cyclic-correlation- and cyclic-spectrum-based methods and extension to space-time speed estimation at the base station in macrocells. In comparison with background art methods, the new estimators of the embodiments of the invention can be used without any need for pilot tones, and are robust to additive stationary noise or interference of any color or distribution. In addition, embodiments of the invention can also be implemented blindly, which can increase the data throughput. Performance results of the estimators of the embodiments of the invention are illustrated via extensive Monte Carlo simulation results.
