摘要： Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.
摘要翻译：本公开的某些方面提供了将非周期性信道状态信息（A-CSI）报告隐含地链接到CSI参考信号（CSI-RS）资源的技术。在一方面，可以指示UE通过UE授权中的显式信令来报告特定的CSI-RS资源。其他方面公开了由UE需要较少信令资源的隐性CSI-RS资源选择技术。代替将CSI-RS资源明确地发送给UE，UE可以基于UE已知的信息，例如隐含地选择用于CSI反馈报告的CSI-RS资源。接收报告请求的子帧。这可以减少UE授权中附加信令的影响。

摘要： A method, an apparatus, and a computer program product for wireless communication are provided for separating control transmissions and data transmissions within the coverage area of a plurality of transmission/reception points or points that are geographically displaced, the plurality of points comprising a macro node and a plurality of remote radio heads (RRHs) coupled to the macro node. Separating control transmissions and data transmissions in the macro node/RRH configuration may allow UEs to be associated with one set of transmission points for data transmissions and the same set or a different set of transmission points for common control signaling. Separating control transmissions and data transmissions may also allow for faster reconfiguration of antenna ports used for UE data transmission compared with reconfiguration via a handover process.

摘要： Aspects disclosed herein relate to channel and interference estimations in a multiple transmission point environment including an eNB and RRHs. In the disclosed aspects, one or more transmission points can signal to a UE to measure channel state conditions based on a first and a second resource pattern. The UE may receive the signaling and perform interference estimation based at least in part on the first resource pattern, and channel estimation based at least in part on the second resource pattern. The UE may generate a channel state report based on the interference and channel estimations, and transmit the channel state report to a transmission point. The eNB may employ the received channel state report in scheduling one or more resources for use by the UE, and may select or adjust network traffic on the first and the second resource pattern, to affect the resulting channel and interference estimation.
摘要翻译：本文公开的方面涉及包括eNB和RRH在内的多传输点环境中的信道和干扰估计。在所公开的方面中，一个或多个传输点可以向UE发信号，以基于第一和第二资源模式测量信道状态条件。 UE可以至少部分地基于第一资源模式接收信令并执行干扰估计，以及至少部分地基于第二资源模式来进行信道估计。 UE可以基于干扰和信道估计产生信道状态报告，并将信道状态报告发送到传输点。 eNB可以使用所接收的信道状态报告来调度一个或多个资源供UE使用，并且可以选择或调整第一和第二资源模式上的网络流量，以影响所得到的信道和干扰估计。

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。
