    • Systems and methodologies are described herein that facilitate control and data multiplexing for uplink (UL) multiple-input-multiple-output (MIMO) communication within a wireless communication system. As described herein, a device conducting uplink MIMO communication in a wireless communication system can multiplex control signaling and data across one or more of a plurality of layers (e.g., corresponding to spatial layers, codewords, etc.) associated with an uplink transmission. Techniques are described herein for selecting layers of a transmission on which to schedule control signaling and selecting offsets to apply to the control signaling scheduled on selected layers. Further, techniques are described herein for leveraging a multi-layer transmission to increase the efficiency of acknowledgement communication. In addition, techniques are described for selecting a modulation and coding scheme (MCS) to apply to control signaling that is combined with data in an uplink multi-layer transmission.
    • 本文描述了便于无线通信系统内的上行链路(UL)多输入多输出(MIMO)通信的控制和数据多路复用的系统和方法。 如本文所述,在无线通信系统中进行上行链路MIMO通信的设备可以跨越与上行链路传输相关联的多个层(例如,对应于空间层,码字等)中的一个或多个层来复用控制信令和数据。 这里描述了用于选择传输的层的技术,其中调度控制信令和选择偏移以应用于在所选择的层上调度的控制信令。 此外,本文描述了用于利用多层传输来提高确认通信的效率的技术。 此外,描述了用于选择适用于与上行链路多层传输中的数据组合的控制信令的调制和编码方案(MCS)的技术。

    • Techniques for transmitting data and resource signals (RS) are provided. According to certain aspects, an access point may determine RS resource locations related to one or more access points in a CoMP set transmitting a common reference signal (CRS), map data transmissions initially over resources other than those related to the RS resource locations, and map remaining data transmissions over resources related to the RS resource locations. According to certain aspects, a wireless device may receive a signal from access points in a coordinated multiple point (CoMP) communication set comprising a common reference signal (CRS) superimposed over data, determine CRS locations in the signal that correspond to the CRS, and decode data from the signal based at least in part on the determined CRS locations.
    • 提供了用于传输数据和资源信号(RS)的技术。 根据某些方面,接入点可以确定与发送公共参考信号(CRS)的CoMP集合中的一个或多个接入点相关的RS资源位置,最初在除与那些与RS资源位置有关的资源之外的资源上映射数据传输,以及 映射与RS资源位置有关的资源上的剩余数据传输。 根据某些方面,无线设备可以从包括叠加在数据上的公共参考信号(CRS)的协作多点(CoMP)通信集中的接入点接收信号,确定信号中对应于CRS的CRS位置,以及 至少部分地基于所确定的CRS位置对来自所述信号的数据进行解码。
