Abstract: Aperiodic channel state information (CSI) reporting is discussed. An example user equipment includes a receiver circuit, processor, and transmitter circuit. The receiver circuit receives transmissions from a plurality of serving cells via a carrier aggregation (CA) mode and receives an aperiodic CSI reporting request indicating a set for CSI reporting. The plurality of serving cells comprises at least six serving cells, and one or more of the plurality is associated with the indicated set. The processor is operably coupled to the receiver circuit and calculates one or more CSI parameters for each serving cell of the plurality that is associated with the indicated set; and generates an aperiodic CSI report based at least in part on the calculated CSI parameters for each serving cell associated with the indicated set. The transmitter circuit transmits the aperiodic CSI report to an Evolved NodeB (eNB) via a physical uplink shared channel (PUSCH).

Abstract: Examples are disclosed for sending or receiving channel state information (CSI) reports associated with coordinated multi-point (CoMP) schemes. The examples include user equipment (UE) constraining CSI feedback to one or more transmission points implementing a CoMP scheme with the UE. The examples also include a transmission point such as an evolved node B (eNB) triggering CSI feedback and receiving a CSI report in response to the trigger. The CSI report generated based on the UE constraining CSI feedback. Constraining CSI feedback may include the UE generating fewer CSI reports, reusing information between CSI reports or increasing an amount of time allowed for processing and generating CSI reports. Other examples are described and claimed.

Abstract: Technology for an UE operable to report channel state information (CSI) for multi-user superposition transmissions (MUST) is disclosed. The UE can process a plurality of power offset parameters that are received from an eNodeB, for the MUST. The UE can perform a downlink channel measurement at a user equipment (UE). The UE can scale the downlink channel measurement using at least one of the plurality of power offset parameters to form one or more scaled downlink channel measurements. The UE can calculate CQI values for the one or more scaled downlink channel measurements. The UE can process, for transmission to the eNodeB, the CQI values for the one or more scaled downlink channel measurements to enable the UE to receive data on a physical downlink shared channel (PDSCH) using multi-user superposition transmission.

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: Wireless device, method, and computer readable media are disclosed for determining which channel status information (CSI) report of a user equipment (UE) to drop from a physical uplink control channel (PUCCH) packet. The method may include determining that a first CSI report and a second CSI report are to be sent in the PUCCH, where the first CSI report has a first reporting type and a first CSI sub-frame set, and the second CSI report has a second reporting type and a second CSI sub-frame set. The method may include determining to drop the first CSI report if the first CSI sub-frame set has a second lower priority than the second CSI sub-frame set. The determination to drop may be further based on a CSI processor index, serving cell index, and the CSI report priority.
