    Abstract: A user equipment (UE) configured to report Channel State Information (CSI) to a wireless network. The UE transmits a first sounding reference signal (SRS) on an uplink (UL) channel, receives a first channel state information reference signal (CSI-RS) on a downlink (DL) channel, wherein the first CSI-RS includes a first configuration of CSI-RS parameters based on the first SRS, performs first CSI-RS measurements based on the first configuration of CSI-RS parameters, transmits a first CSI report including the first CSI-RS measurements, transmits a second SRS on the UL channel, receives a second CSI-RS on the DL channel, wherein the second CSI-RS includes a second configuration of CSI-RS parameters based on the second SRS, performs second CSI-RS measurements based on the second configuration of CSI-RS parameters and transmits a second CSI report including the second CSI-RS measurements.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing designs for configurations of resource elements to carry reference signals for a user equipment (UE). A reference signal can be processed by the UE according to the configuration of resource elements to carry reference signals. The configurations can be determined by the base station, and received from the base station by the UE. The base station determines the configurations based on information or parameters provided by the UE, e.g., a coherence bandwidth of the channel, a coherence time of the channel, a preference associated with channel status information reference signal, or a preference associated with demodulation reference signal for the UE.
