    • Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.
    • 描述了使用空间正交资源发射分集(SORTD)从多个发射天线发射数据的技术。 对于SORTD方案,可以将不同的正交资源分配给每个发射天线。 可以使用多个正交资源从多个发射天线发送数据。 在一种设计中,UE可以处理至少一个信息比特(例如,具有联合或独立编码)以获得第一和第二组至少一个调制符号。 UE可以使用第一正交资源处理第一组调制符号以从第一发射天线发射。 UE可以使用第二正交资源处理第二组调制符号以从第二发射天线发射。 每个正交资源可以包括不同的参考信号序列或不同的参考信号序列集合和正交序列。

    • Systems and methodologies are described that facilitate cycling through precoders for transmitting wireless network communications in a time domain. The precoders can be cycled according to a precoder sequence for each data symbol transmission. When the last precoder is selected the cycle can begin again, a new precoder sequence can be received or defined, and/or the like. A precoder sequence related to a subset of precoders present in a wireless device can be defined sequentially, cyclically shifted according to an identifier or one or more communications parameters, randomly, pseudo-randomly according to an identifier or one or more communications parameters, and/or the like. In addition, the precoder sequence can be utilized to select a precoder for one or more retransmissions. Such cycling of precoders can increase transmit diversity.
    • 描述了有助于循环通过用于在时域中发送无线网络通信的预编码器的系统和方法。 预编码器可以根据每个数据符号传输的预编码器序列循环。 当选择最后一个预编码器时,循环可以再次开始,可以接收或定义新的预编码器序列和/或类似物。 可以根据标识符或一个或多个通信参数根据标识符或一个或多个通信参数随机地随机地定义与存在于无线设备中的预编码器子集相关的预编码器序列和/ 或类似物。 此外,预编码器序列可用于为一个或多个重传选择预编码器。 预编码器的这种循环可以增加发射分集。
