Indicating beam property changes across polarizations in non-co-located polarized array designs

An apparatus for wireless communications at a user equipment (UE), 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 apparatus to:
• receive, from a relay node supporting relay procedures between at least the UE and a network entity, capability information indicating that the relay node supports relay signaling using a first antenna panel corresponding to a first polarization and a second antenna panel corresponding to a second polarization;
• transmit to the relay node, the network entity, or both, based at least in part on receiving the capability information, an indication of a beam direction for the relay signaling at the UE;
• and
• receive downlink signaling via the relay node according to one or more transmission properties that are based at least in part on the indication of the beam direction for the relay signaling at the UE.
