Abstract

Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may be configured for carrier aggregation (CA) in which a plurality of component carriers (CCs) are aggregated. The UE may determine a mapping of the CCs to a plurality of antenna panels for downlink reception, wherein a subset of the CCs are mapped to each antenna panel. The UE may transmit, to the gNB, radio resource control (RRC) signaling that indicates information related to the mapping. The gNB may, based at least partly on the mapping, determine, for each CC: a first scheduled time period for transmit beam refinement, and a second scheduled time period for receive beam refinement at the UE.
