    Abstract: An UL channel for a UE is measured based on reference signal (s) to determine UL channel information. DL channel information is inferred based on UL-DL channel reciprocity and the determined UL channel information. Reporting is configured based on the inferred DL channel information for CSI for the UE and resource (s) are allocated for the UE to use to report the CSI. Information is signaled to the UE indicating a configuration of the reporting of CSI and the resource (s). DL reference signal (s) are transmitted toward the UE to be used for determination of the CSI. Report (s) of CSI are received on the allocated resource (s). The UE receives the configuration, determines the CSI using the configuration and the received DL reference signal (s) and fits the determined CSI into the allocated resource (s). The UE transmits the determined CSI on the allocated resource (s).

    Abstract: Method, apparatuses, and computer program product for overhead reduction are provided. One method may include determining a channel sparsity. The method may also include determining a shut-off ratio based on the channel sparsity ratio. In addition, the method may include providing feedback to a network node of a suggested shutoff pattern or a shut-off index from a shut-off table for reference signals, and receiving instructions from the network node to execute a shut-off pattern or a shut-off index selected by the network node. Further, the method may include executing a shut-off procedure according to the shut-off pattern or the shut-off index selected by the network node.

    Abstract: In accordance with some embodiments, an apparatus may include means for determining time and frequency domain correlation of at least one channel with respect to direction of at least one dominant Eigen beam. The apparatus may further include means for applying at least one common channel hardening matrix within the correlation time and bandwidth based on a first time periodicity. The apparatus may further include means for applying a 2-dimensional fast fourier transform within the correlation time and bandwidth associated with the at least one common channel hardening matrix. The apparatus may further include means for reporting at least one tap location based on a second time periodicity that is associated with the at least one common channel hardening matrix to at least one network entity.
