    • 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).

    • 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.

    • Systems and methodologies are described that facilitate resource allocation and management in a wireless communication system. As described herein, a resource grid structure can be utilized to allocate resources for respective users corresponding to a given channel (e.g., a Physical Uplink Control Channel (PUCCH)). The resource grid can be constructed using one or more cyclic shifts and a set of four orthogonal covers to provide improved efficiency in resource usage. Further, slots in the resource grid can be allocated to respective users based on user indexes via one or more resource allocation functions. For example, a resource allocation function can step along a first orthogonal cover at increasing cyclic shifts, alternate between second and fourth orthogonal covers at increasing cyclic shifts upon exhaustion of the first orthogonal cover, and step through a third orthogonal cover at increasing cyclic shifts upon exhaustion of the second and fourth orthogonal covers.
    • 描述了在无线通信系统中促进资源分配和管理的系统和方法。 如本文所描述的,可以利用资源网格结构来分配对应于给定信道(例如,物理上行链路控制信道(PUCCH))的各个用户的资源。 可以使用一个或多个循环移位和一组四个正交覆盖来构建资源网格,以提供资源使用的提高的效率。 此外,资源网格中的时隙可以经由一个或多个资源分配功能基于用户索引分配给各个用户。 例如,资源分配功能可以在增加循环移位的情况下沿着第一正交覆盖层步进,在第一正交覆盖层耗尽时以增加的循环移位在第二和第四正交覆盖之间交替,并且以增加循环移位的步骤穿过第三正交覆盖 第二和第四正交盖的耗尽。

    • Providing a coding scheme for wireless communication downlink reference signals is described herein. By way of example, a dedicated reference signal is mapped (108) (204) to resources of a wireless channel as a function of an identifier (ID) (112) (210) of a cell in which the reference signal is transmitted. The function can be similar to mapping functions employed for common reference signals, or can be distinct from such functions. As one example of the latter, a dedicated reference signal mapping function can be shifted in time or frequency with respect to the common reference signal mapping function. By employing a mapping function based on cell ID, noise caused by concurrent transmission of reference signals can be mitigated in a manner readily determined by terminals in a wireless network.
    • 本文描述了提供无线通信下行链路参考信号的编码方案。 作为示例,作为发送参考信号的小区的标识符(ID)(112)(210)的函数,专用参考信号被映射(108)(204)到无线信道的资源。 该功能可以类似于用于公共参考信号的映射函数,或者可以与这些功能不同。 作为后者的一个例子,相对于公共参考信号映射函数,专用参考信号映射函数可以在时间或频率上移位。 通过采用基于小区ID的映射功能,可以以无线网络中的终端容易确定的方式来减轻由参考信号的并发传输引起的噪声。

    • Aspects describe maximizing a Euclidean distance for an ACK transmission as a function of the number of bits in a HARQ-ACK and a modulation order. Encoding includes placing escape sequences in the HARQ-ACK, wherein the number of escape sequences is based on the number of bits and the modulation order. Multiple encoded ACK blocks are combined to obtain a vector sequence that is multiplexed with the encoded data and interleaved, such as on a "time-first" manner. Scrambling is performed as a function of the size and the modulation order. For a 1-bit ACK, the scrambling is performed to achieve any two corners in any constellation for transmission for the ACK. For a 2-bit ACK, the scrambling is performed to achieve any four corners in any constellation for transmission for the ACK.
    • 方面描述了根据HARQ-ACK和调制阶数中的比特数来最大化用于ACK传输的欧几里德距离。 编码包括将转义序列放置在HARQ-ACK中,其中转义序列的数量基于比特的数量和调制阶数。 多个编码的ACK块被组合以获得与编码数据复用并被交织的矢量序列,诸如以“时间优先”的方式。 加扰是根据大小和调制顺序来执行的。 对于1比特ACK,执行加扰以实现任何星座中的任何两个角以用于ACK的传输。 对于2比特ACK,执行加扰以实现任何星座中的任何四个角以用于ACK的传输。
