    • A method, apparatus, and system for transmitting and controlling uplink diversity signals in a mobile communication device. While in a soft handoff situation, a mobile communications device may receive a phase feedback signal from a non-serving base station. The mobile device may calculate a modified phase parameter based on the phase feedback signal from the non-serving base station in order to minimize interference with the non-serving base station, for example, by calculating a modified value of a phase difference in a direction opposite to the direction desired by the non-serving base station. In some embodiments of the invention, the mobile device may determine whether to calculate the modified phase parameter in a direction opposite to the direction indicated by the phase feedback signal of the non-serving base station based on a comparison of power feedback signals received from the non-serving and serving base stations.
    • 一种用于在移动通信设备中发送和控制上行链路分集信号的方法,装置和系统。 在软切换情况下,移动通信设备可以从非服务基站接收相位反馈信号。 移动设备可以基于来自非服务基站的相位反馈信号来计算修改的相位参数,以便最小化对非服务基站的干扰,例如,通过计算方向上的相位差的修改值 与非服务基站所期望的方向相反。 在本发明的一些实施例中,移动设备可以基于从所述非服务基站接收的功率反馈信号的比较来确定是否在与非服务基站的相位反馈信号所指示的方向相反的方向上计算修改的相位参数 非服务和服务基站。

    • Communication is performed for a first communication device having a set of antenna elements. A quality-indication signal is received from a second communication device (e.g., a basestation). A complex weighting is calculated based on the quality-indication signal. A pre-transmission signal is modified based on the complex transmit diversity weighting to produce a set of modified-pre-transmission signals, wherein the modifications are symmetric by making approximately half the magnitude of the transmit diversity modification to one signal in a first direction, and approximately half the magnitude of the transmit diversity modification to the other signal in a second direction, opposite the first direction. Each modified pre-transmission signal from the set of modified-pre-transmission signals is uniquely associated with an antenna element from the set of antenna elements. The set of modified-pre-transmission signals is sent from the set of antenna elements to produce a transmitted signal.
    • 对具有一组天线元件的第一通信设备执行通信。 从第二通信设备(例如,基站)接收质量指示信号。 基于质量指示信号计算复数加权。 基于复合发射分集加权来修改预发射信号以产生一组修改预传输信号,其中通过使发射分集修改的大致一半在一个第一方向上的一个信号,所述修改是对称的, 以及在与第一方向相反的第二方向上的另一信号的发射分集修改的大约一半的幅度。 来自修改后的预传输信号的每个经修改的预发射信号与天线元件集合中的天线元件唯一地相关联。 经修改的预传输信号的集合从天线元件组发送以产生发射信号。
