Title:
CHANNEL STATE INFORMATION REFERENCE SIGNAL (CSI-RS) RESOURCE ACTIVATION OR DEACTIVATION WITHIN A RESOURCE SET
Document Type and Number:
WIPO Patent Application WO/2022/077414
Kind Code:
A1
Abstract:
This disclosure provides systems, methods and apparatus for channel state information reference signal (CSI-RS) resource activation or deactivation within a resource set. In one aspect, a base station (BS) may transmit control signaling to a user equipment (UE) including an indication to switch an activity status of one or more CSI measurement resources within a CSI resource set from an activated state or a deactivated state to the other. The control signaling may include a bitmap indication for the activity status for the one or more CSI measurement resources or a CSI measurement resource identifier for each CSI measurement resource in an activated state. The UE may transmit a CSI report including information from measuring a channel state, a channel interference, or both for the one or more CSI measurement resources based on the activity status of each.
