Beam-based spatial adaptation with asymmetric antenna panels

A network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
• output, to a user equipment (UE), one or more downlink reference signals via one or more receive beams of the UE;
• obtain a beam report based at least in part on a change in a quantity of antenna components of the UE per reference signal port, the beam report comprising a request to perform uplink sounding at the UE or comprising one or more respective downlink rank indicators associated with respective beams of the one or more receive beams;
• and
• communicate one or more signals with the UE based at least in part on the beam report.

A method for wireless communications at a user equipment (UE), comprising:

• receiving, from a network entity, one or more downlink reference signals via one or more receive beams of the UE;
• performing one or more measurements of the one or more downlink reference signals;
• and
• transmitting a beam report based at least in part on a capability of the UE, the one or more measurements of the one or more downlink reference signals, and a change in a quantity of antenna components of the UE per reference signal port, the beam report comprising a request to perform uplink sounding at the UE or comprising one or more respective downlink rank indicators associated with respective beams of the one or more receive beams.
