Quasi co-location information for 3d beamforming in holographic multiple-input multiple-output systems

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, wherein the instructions are executable by the processor to:
• receive, from a base station, control signaling indicating a quasi co-location configuration associated with multiple-input multiple-output (MIMO) communications within a distance threshold from the base station;
• receive, from the base station, an indication of a downlink transmission associated with the quasi co-location configuration within the distance threshold for MIMO communications from the base station;
• select a beam to receive the downlink transmission within the distance threshold for MIMO communications from the base station based at least in part on the quasi co-location configuration.
