摘要： Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support hybrid automatic repeat request (HARQ) schemes to improve the likelihood that information is received correctly over a wireless communications link. In HARQ, when a transmitting device determines that a receiving device failed to successfully decode a transmission of information, the transmitting device may retransmit the information to the receiving device. In some cases, HARQ techniques may be used for communications associated with different types of services. In such cases, to keep the latency of communications within a latency budget for a particular type of service, wireless devices may utilize the techniques described herein to dynamically terminate HARQ retransmissions. For instance, a transmitting device may avoid retransmitting information when an amount of time that has elapsed since an original transmission of the information has exceeded the latency budget.

摘要： Aspects of the disclosure relate to methods and apparatus of time-domain multiplexing (TDM) for reference signals (RS) and data using a modified cyclic prefix. A reference signal (RS) and data are multiplexed either in a single symbol or in two time consecutive symbols that respectively including the RS and data. The cyclic prefix (CP) is added to the single symbol using a portion of the RS or to a first symbol of the two time consecutive symbols using a portion of the RS. The CP may be copied from the RS or the end of the symbol, but not the data, in a manner that affords a virtual Time Division Multiplexing (TDM) of the RS and data before discrete Fourier transform (DFT) spreading is performed in a transceiver to provide lower peak to average power ratios and no Inter-symbol interference.

摘要： Certain aspects of the present disclosure relate to techniques that may be used to discover transmission points in heterogeneous networks (HetNet) that involves coordinated multi-point (CoMP) transmission and reception. Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a configuration indicating distinct resources used by each of a plurality of different transmission points involved in coordinated multipoint (CoMP) operations with the UE for transmitting discovery reference signals (RSs), receiving distinct discovery RSs transmitted from the plurality of different transmission points, and calculating at least one of path loss or reference signal received power (RSRP) estimations for each of the transmission points based on the distinct discovery RSs.

摘要： In macro/RRH setups, channel state information reference signals (CSI-RS) and demodulation reference signals (DM-RS) may be used to decouple control and data transmission. Data transmission (e.g. for LTE Rel 10 and beyond) may be based on CSI-RS and DM-RS, while control may be received from a different set of cells or TxPs via CRS. Certain aspects of the present disclosure introduce a reporting framework, in which configuration of data-serving cells/TxPs may be carried out based on CSI-RS. In certain aspects, a new concept of CSI-RS groups, i.e., a set of CSI-RS ports that a UE considers as one group for precoding matrix indicator (PMI)/channel quality indicator (CQI)/rank indicator (RI) reporting, may be defined.
摘要翻译：在宏/ RRH设置中，可以使用信道状态信息参考信号（CSI-RS）和解调参考信号（DM-RS）来去耦合控制和数据传输。数据传输（例如，对于LTE Rel 10及其以外）可以基于CSI-RS和DM-RS，而可以经由CRS从不同的小区集合或TxP接收控制。本公开的某些方面引入了报告框架，其中可以基于CSI-RS来执行数据服务小区/ TxP的配置。在某些方面，CSI-RS组的新概念，即UE认为一组用于预编码矩阵指示符（PMI）/信道质量指示符（CQI）/秩指示符（RI）报告）的一组CSI-RS端口，可以被定义。

摘要： Described is a technology for computing visual and textual summaries for tagged image collections. Heterogeneous affinity propagation is used to together identify both visual and textual exemplars. The heterogeneous affinity propagation finds the exemplars for relational heterogeneous data (e.g., images and words) by considering the relationships (e.g., similarities) within pairs of images, pairs of words, and relationships of words to images (affinity) in an integrated manner.
