Abstract: Apparatuses and methods for indicating and performing interference measurements. A method for performing interference measurements includes identifying a CSI-IM configuration for the UE to perform interference measurement. The method includes determining whether the CSI-IM configuration includes a subset of a total number of frequency resources configured for CSI-IM in the wireless communication system. The method includes measuring interference based on the identified CSI-IM configuration. Additionally, the method includes sending feedback based on the measured interference. The method for performing interference measurements may also include determining whether to perform interference measurements based on all downlink subframes or only a portion of the downlink subframes. Additionally, the method may include performing interference measurement based on the subframe determination.

Abstract: Coordinate multi-point (CoMP) transmission is facilitated by resolving collisions between feedback reporting. Based upon the conditions within the network, collision resolution may be by dropping a channel report during a subframe, multiplexing channel reports from a plurality of user equipment, compressing channel reports a plurality of user equipment, and combined reporting, either through joint reports or by using carrier aggregation, for conditions between a user equipment and a plurality of transmission points. New signaling and reporting formats facilitate selection of a collision resolution suitable for current network conditions.

Abstract translation: 通过解决反馈报告之间的冲突，便于协调多点（CoMP）传输。 基于网络中的条件，冲突解决可以是通过在子帧期间丢弃信道报告，从多个用户设备复用信道报告，压缩信道报告多个用户设备，以及组合报告，通过联合报告或通过 使用载波聚合，用于用户设备和多个传输点之间的条件。 新的信令和报告格式有助于选择适合当前网络条件的冲突解决方案。

Abstract: In a Coordinated Multipoint (CoMP) wireless network comprising a plurality of transmission points (TPs), a user equipment (UE) performs a method of determining aggregated channel quality information (CQI). The method includes receiving signals corresponding to a joint transmission from the plurality of TPs in the CoMP network. The method also includes making an assumption about a transmission scheme of the joint transmission from the TPs. The method further includes determining aggregated CQI corresponding to the joint transmission based on the assumption about the transmission scheme. The method still further includes transmitting the aggregated CQI to the network.
