  • Publication number: 20230314983
    Abstract: Systems and methods relating to accurate Channel State Information (CSI) measurements for a License Assisted Secondary Cell (LA SCell) are disclosed herein. An exemplary user equipment enabled includes a transceiver, at least one processor, and memory containing instructions executable by the at least one processor whereby the user equipment operates to detect whether a downlink control information (DCI) message indicating that a Channel State Information Reference Symbol (CSI-RS) transmission from an LA SCell of the user equipment is present in a subframe. When the user equipment detects that the DCI message indicates that a CSI-RS transmission from the LA SCell is present in the subframe, it processes a CSI-RS measurement. When the user equipment detects that the DCI message does not indicate that a CSI-RS transmission from the LA SCell is present in the subframe, it refrains from processing the CSI-RS measurement.
