Abstract: Embodiments of providing enhanced interference measurements for CSI feedback are generally described herein. In some embodiments, CSI-IM resources are used by UE to perform interference measurements. The serving cell determines a hopping pattern for varying a position of the determined CSI-IM resources in subframes transmitted to the served UE. The determined CSI-IM resources and the determined CSI-IM resources hopping pattern are transmitted to the served UE. The serving node transmits a zero-power (ZP) CSI-RS. The serving node receives an interference measurement from the served UE based on CSI-IM and ZP CSI-RS provided to the served LE from the serving cell. Collisions between the CSI-IM of the serving node and CSI-IM of the non-serving nodes are minimized by the determined CSI-IM resources hopping pattern.

Abstract: Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (UE) experiences enhanced signal reception and/or reduced interference. In order to optimally implement downlink CoMP, a serving cell needs to obtain channel state information (CSI) for the downlink channels from the multiple transmission points to the UE. This disclosure deals with radio resource control (RRC) signaling for configuring the UE to obtain and report CSI for those downlink channels.

Abstract translation: 协调多点（CoMP）涉及协调其各自传输的多个传输点或小区，使得目标用户设备（UE）经历增强的信号接收和/或减少的干扰。 为了最佳地实现下行链路CoMP，服务小区需要获得从多个传输点到UE的下行链路信道的信道状态信息（CSI）。 本公开涉及用于配置UE获得并报告那些下行链路信道的CSI的无线电资源控制（RRC）信令。

Abstract: Methods, apparatuses, and systems are described related to interference averaging to generate feedback information and interference averaging to demodulate receives signals. In embodiments, an evolved Node B (eNB) may transmit interference averaging information to a user equipment (UE) including a time domain averaging indicator indicating a time domain averaging window to be used by the UE for averaging interference measurements in a time domain or a frequency domain averaging indicator to indicate a frequency domain averaging window to be used by the UE for averaging interference measurements in a frequency domain. Additionally, or alternatively, the eNB may transmit an interference resource group (IRG) indicator to the UE to indicate an IRG over which the UE is to perform interference averaging to facilitate demodulation of signals received by the UE from the eNB.

Abstract: Embodiments for providing fast modulation and coding scheme adaptation for LTE regardless of transmission using single-user multiple-input and multiple-output (SU-MIMO) or multiple-user multiple-input and multiple-output are generally described herein. In some embodiments, channel state information reference signals are sent to user equipment by a node. First channel quality indication feedback based on the channel state information reference signals is received from the user equipment. Physical downlink shared channel data and demodulation reference signals are transmitted using a first modulation and coding scheme based on the first channel quality indication feedback. Second channel quality indication feedback based on measurements performed by the user equipment on the demodulation reference signals is received by a node. Physical downlink shared channel data is transmitted using a second modulation and coding scheme based on the second channel quality indication feedback.
