    • Techniques for efficiently multiplexing a reference signal and data on different sets of subcarriers in the same symbol period are described. In one design, a user equipment (UE) performs a discrete Fourier transform (DFT) on a set of modulation symbols for data to obtain data symbols. The UE also obtains reference symbols generated based on a reference signal sequence corresponding to a cyclic shift of a base sequence. The UE maps the reference symbols to a first set of subcarriers and maps the data symbols to a second set of subcarriers. The UE then generates a transmission symbol based on the mapped reference symbols and the mapped data symbols. The UE may also transmit reference signals and data (i) in multiple symbol periods of a slot or a subframe and/or (ii) from multiple antennas using frequency division multiplexing (FDM) or code division multiplexing (CDM).
    • 描述了用于在相同符号周期中有效地多路复用参考信号和不同副载波组上的数据的技术。 在一个设计中,用户设备(UE)对用于数据的一组调制符号执行离散傅立叶变换(DFT)以获得数据符号。 UE还获得基于与基序列的循环移位相对应的参考信号序列而生成的参考符号。 UE将参考符号映射到第一组子载波并将数据符号映射到第二组子载波。 然后,UE基于映射的参考符号和映射的数据符号生成传输符号。 UE还可以使用频分复用(FDM)或码分复用(CDM)在时隙或子帧的多个符号周期中和/或(ii)从多个天线发送参考信号和数据(i)。

    • 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。
