CHANNEL STATE INFORMATION REFERENCE SIGNAL CONFIGURATIONS FOR DYNAMIC ANTENNA PORT ADAPTATION: abstract simplified (17700207)

The abstract describes methods, systems, and devices for wireless communications. It explains that a network entity can send a message called a channel state information (CSI) report, which contains multiple codebook configurations. A user equipment (UE) receives this CSI report, which includes a set of codebook configurations associated with a set of antenna port configurations. The UE then sends a CSI report back to the network entity, indicating one or more codebook configurations from the set it received. The CSI included in the report is based on the selected codebook configurations. Finally, the UE can communicate with the network entity using the channel state information report that indicates the selected codebook configurations.
