Title:
METHOD AND APPARATUS FOR APERIODIC REFERENCE SIGNAL TRANSMISSION AND RECEPTION
Document Type and Number:
WIPO Patent Application WO/2020/256516
Kind Code:
A3
Abstract:
A method for operating a user equipment (UE) for aperiodic channel state information reference signal (CSI-RS) reception comprises receiving aperiodic CSI-RS configuration information including a CSI-RS triggering offset; receiving downlink control information (DCI) via a physical downlink control channel (PDCCH), where the DCI triggers an aperiodic CSI-RS; and determining the CSI-RS triggering offset based on the CSI-RS configuration information, wherein the CSI-RS triggering offset is configured from a first set when μPDCCH <μCSIRS, and the CSI-RS triggering offset is configured from a second set when μPDCCH > μCSIRS, wherein μPDCCH and μCSIRS are subcarrier spacing configurations for the PDCCH and the aperiodic CSI-RS, respectively, and receiving the aperiodic CSI-RS in a slot Ks determined based on the CSI-RS triggering offset, a slot containing the triggering DCI, and the subcarrier spacing configurations (μPDCCH and μCSIRS).
