    • An improved method and apparatus for Mobile Transmit Diversity (MTD), or Uplink Transmit Diversity (ULTD) is disclosed. The mobile device either selects the best antenna at any given time, or transmits from both antennas using the best beam forming phase without feedback from the base station on which antenna to transmit from or which phase to use if using two antennas. Essentially operating in Open Loop MTD, a Hybrid Phase Sweeping algorithm requires testing of a fraction of phase hypotheses resulting in improved base station performance and higher data rates for the user. One among the set of transmission test phase hypotheses (for example: 0,90,180 and 270 degrees) is selected using a turn direction (left or right). The uplink transmission quality for the selected test phase hypotheses during a test period is compared with the uplink transmission quality during steady state. The current phase is changed to the test phase if the first quality value is better.
    • 公开了一种用于移动发射分集(MTD)或上行链路发射分集(ULTD)的改进的方法和装置。 移动设备可以在任何给定时间选择最佳天线,或者使用最佳波束形成相位从两个天线发射,如果使用两个天线,则从哪个天线发射哪个天线或哪个相位使用来自基站的反馈。 基本上在开环MTD中运行,混合相位扫描算法需要测试一部分相位假设,从而提高用户的基站性能和更高的数据速率。 使用转向(左或右)选择传输测试阶段假设(例如:0,90,180和270度)中的一个。 在稳定状态期间将测试期间所选择的测试阶段假设的上行链路传输质量与上行链路传输质量进行比较。 如果第一个质量值更好,当前阶段将更改为测试阶段。
