Abstract: Dynamic transmission of non-zero power channel state information resource signals and interference measurement resources is described. Such dynamic transmission reduces or eliminates a need to buffer and store channel and interference measurements The described approach also reduces the overhead due to transmission of those resources and enables flexible time-domain channel state information requests.

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: Technology for a user equipment (UE) operable to report periodic channel state information (CSI) to an eNodeB is disclosed. The UE can determine a reporting period (Npd) of a serving cell of the UE. The UE can determine a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell of the UE. The UE can encode multiple periodic CSI reports for transmission to the eNodeB using a physical uplink control channel (PUCCH) on the primary cell according to the reporting period Npd.

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 UE 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: 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: Technology for adjusting a receiver timing of a wireless device in a Coordinated MultiPoint (CoMP) system is disclosed. One method can include the wireless device receiving a plurality of node specific reference signals (RSs) from a plurality of cooperating nodes in a coordination set of the CoMP system. The coordination set includes at least two cooperating nodes. The wireless device can estimate a composite received RS timing from a plurality of received RS timings generated from the plurality of node specific RSs. The received RS timings represent timings from the at least two cooperating nodes. The wireless device can adjust the receiver timing based on the composite received RS timing. A node specific RS can include a channel-state information reference signal (CSI-RS).

Abstract: Coordinated Multipoint (CoMP) involves multiple transmission points or cells coordinating their individual transmissions so that a target user equipment (LTE) 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（LTE）经历增强的信号接收和/或减小的干扰。 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。
