The UE may also determine a second channel information reporting mode to use, determine second channel information related to multiple cells in the CoMP measurement set, and send the second channel information in accordance with the second channel information reporting mode. A plurality of channel feedback configurations may be supported, including a single-stage, a two-stage, and/or a one-shot channel configurations.

    Abstract: Techniques for transmitting UE-specific reference signals (UE-RSs) in a wireless network are described. In an aspect, a UE-RS may be transmitted in different manners depending on the number of layers used for data transmission. In one design, a cell may determine subcarriers for a UE-RS based on a frequency shift if data is transmitted on one layer and based on a predetermined set of subcarriers (with no frequency shift) if data is transmitted on multiple layers. In another aspect, a UE-RS may be transmitted on subcarriers determined based on a frequency shift for data transmission on multiple layers. In yet another aspect, a UE-RS may be transmitted from a plurality of cells to a UE for coordinated multi-point (CoMP). In yet another aspect, a UE-RS may be transmitted in a data section of a subframe including only the data section.

    Abstract: Providing for improved error control signaling in wireless communications is disclosed herein. By way of example, multiple transmissions can be conducted for a HARQ process prior to a scheduled feedback signal on the HARQ process, causing a receiving device to combine the multiple transmissions, rather than treat them as separate transmissions. In this manner, multiple transmissions can be employed to increase overall receive energy, without violating maximum transmit power constraints in a wireless communication. Further, these multiple transmissions can be configured based on prevailing signal strength at the receiving device, or based on processing capabilities of the receiving device, providing flexible protocols that can accommodate advanced as well as legacy UEs in wide range of wireless conditions.

    Abstract translation: 在此公开了在无线通信中提供改进的差错控制信令。 作为示例,可以在HARQ过程上的调度的反馈信号之前对HARQ过程进行多个传输,使得接收设备组合多个传输,而不是将它们视为单独的传输。 以这种方式,可以使用多次传输来增加总体接收能量,而不会违反无线通信中的最大传输功率约束。 此外,可基于接收设备处的主要信号强度或基于接收设备的处理能力来配置这些多重传输,从而提供灵活的协议,其可在宽范围的无线条件下适应先进的以及传统的UE。

    Abstract: 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.

    Abstract: In a wireless communication system, SFBC-based (Space-Frequency Block-Code) transmission diversity schemes provide enhancement for multiple antennas, such as the illustrative four, in order to achieve better performance than SFBC-FSTD (SFBC- Frequency Switching Transmit Diversity) alone. SFBC-PFSTD (Precoded Frequency Switching Transmit), which is multiplying a precoding matrix to the SFBC-FSTD signals, opens up the possibility of utilizing the pilot tones in synchronization channels (SSC and/or PSC) to enhance the channel estimation performance for antenna 2 and 3 that have only the half as many pilot tones as antenna 0 and 1. Further improvements are disclosed for use of Frequency Time Switching Transmit Diversity (FTSTD) and Precoding Vector Switch.

    Abstract: 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.

    Abstract: Systems and methodologies are described that provide techniques for efficient cell search in a wireless communication system. In one aspect, a frequency reuse pattern can be generated by applying frequency shifts to reference signals transmitted from cells that provide coverage for a NodeB based on cell IDs or cell group IDs for the cells. The frequency shifts applied to reference signals can then be utilized as a basis for multiplexing reference signals from different cells using frequency division multiplexing (FDM) or a combination of FDM and other multiplexing techniques. Other adjustments to reference signals transmitted from respective cells, such as transmit power adjustments, can further be made to improve detection performance.
