Indicating a polarization state change at a user equipment (UE) in accordance with a change in a UE's geometric configuration

A user equipment (UE), comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors and storing processor-executable code that, when executed by the one or more processors, is configured to cause the UE to:
• transmit, to a network node, a first message indicating a uni-polarization communication state or a dual-polarization communication state of an antenna array architecture of the UE in accordance with the UE changing from a first geometric configuration to a second geometric configuration, or vice versa, the antenna array architecture forming:
• a split antenna array associated with the uni-polarization communication state when the UE is configured according to the first geometric configuration;
• and
• a single antenna array associated with the dual-polarization communication state when the UE is configured according to the second geometric configuration;
• receive, from the network node, one or more reference signals (RSs) in accordance with transmitting the first message;
• and
• transmit, to the network node, a second message indicating one or more channel characteristics and one or more device characteristics associated with measurements of the one or more RSs.

A method for wireless communication at a network node, comprising:

• receiving, from a user equipment (UE), a first message indicating a uni-polarization communication state or a dual-polarization communication state of an antenna array architecture of the UE in accordance with the UE changing from a first geometric configuration to a second geometric configuration, or vice versa, the antenna array architecture forming:
• a split antenna array associated with the uni-polarization communication state when the UE is configured according to the first geometric configuration;
• and
• a single antenna array associated with the dual-polarization communication state when the UE is configured according to the second geometric configuration;
• transmitting one or more reference signals (RSs) in accordance with transmitting the first message;
• and
• receiving, from the UE, a second message indicating one or more channel characteristics and one or more device characteristics associated with measurements of the one or more RSs.
