CHANNEL STATE INFORMATION REFERENCE SIGNAL (CSI-RS) FOR MULTIPLE BEAM TRANSMISSIONS

Abstract:

Certain aspects of the present disclosure provide techniques for channel state information reference signal (CSI-RS) for multiple beam transmissions. In an example, a first CSI-RS triggering state of one or more CSI-RS triggering states indicates a CSI-RS resource set and associated transmission configuration indication (TCI) states. The CSI-RS resource set includes a plurality of CSI-RS resources. Each CSI-RS resource of the plurality of CSI-RS resources is associated with one or more corresponding TCI states as indicated by the first CSI-RS triggering state. A first CSI-RS resource of the plurality of CSI-RS resources is associated with a first plurality of TCI states as indicated by the first CSI-RS triggering state.
