Holographic-mimo field type indication

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

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a wireless device, an indication of a field type of a field between the UE and the wireless device;
• select between a first set of beam weight vectors and a second set of beam weight vectors based at least in part on the field type;
• and
• communicate a reference signal with the wireless device using a beam generated using a first beam weight vector from the selected set of beam weight vectors.

An apparatus for wireless communication at a base station, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• transmit, to a user equipment (UE), an indication of a field type of a field between the UE and the base station, the indication of the field type indicating to use one of a first set of beam weight vectors or a second set of beam weight vectors;
• and
• communicate a reference signal with the UE based at least in part on transmitting the indication of the field type that indicates one of the first set of beam weight vectors or the second set of beam weight vectors.
