Techniques are described herein for activating and/or deactivating a semi-persistent configuration for one or more channel state information reference signal (CSI-RS) resource sets using a medium access control (MAC) control element (CE) and/or radio resource control (RRC) signaling. The MAC CE may include an indicator to indicate whether a semi-persistent configuration for a CSI resource set that includes one or more CSI resources is to be activated or deactivated. The MAC CE may also include identifiers for each of the CSI resource sets having the semi-persistent configuration activated or deactivated. In some cases, RRC messages may be used to communicate quasi-collocation (QCL) relationships associated with the CSI resources of the CSI resource sets. In some cases, the MAC CE may communicate at least some of or a portion of the information related to QCL relationships.
