Configure Measurement Gaps for CSI-RS from Neighbor Cells in NR

Abstract:

Embodiments of a generation Node-B (gNB), User Equipment (UE) and methods to configure measurement gaps are generally described herein. A serving cell gNB may transmit, to a neighbor cell gNB, a channel state information reference signal (CSI-RS) status request message and may receive, from the neighbor cell gNB 105, a CSI-RS status update message. The serving cell gNB may determine, based on timing information in the CSI-RS status update message, a measurement gap to be reserved for transmission of CSI-RS from the neighbor cell gNB to a UE that is served by the serving cell gNB. The serving cell gNB may transmit, to the UE, control signaling that indicates the measurement gap. The serving cell gNB may receive, from the UE, a measurement report that indicates a signal quality measurement based on the CSI-RS from the neighbor cell gNB.
