Passive or semi-passive device with polarization conversion capability

A method of wireless communication at a network entity, comprising:

• receiving, from a passive node or a semi-passive node, a capability indication that indicates first support for at least one of a first mode of operation with polarization conversion or a second mode of operation without the polarization conversion;
• transmitting, from the network entity to the passive node or the semi-passive node, an access control indication that indicates second support for at least one of the first mode of operation with the polarization conversion or the second mode of operation without the polarization conversion;
• monitoring for a backscattered signal from the passive node or the semi-passive node based on the first support indicated in the capability indication and the second support indicated in the access control indication, wherein the backscattered signal comprises the first mode of operation or the second mode of operation;
• and
• communicating with the passive node or the semi-passive node in response to a mode of operation of the backscattered signal that is actively supported as indicated by the access control indication and the capability indication received from the passive node or the semi-passive node.

An apparatus for wireless communication at a passive or semi-passive node, comprising:

• at least one memory;
• and
• at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to cause the apparatus to:
• transmit, from the passive or semi-passive node, a capability indication that indicates first support for at least one of a first mode of operation with polarization conversion or a second mode of operation without the polarization conversion;
• receive, from a network entity, an access control indication that indicates second support for at least one of the first mode of operation with the polarization conversion or the second mode of operation without the polarization conversion;
• transmit, to the network entity, a backscattered signal comprising the first mode of operation or the second mode of operation based on the first support indicated in the capability indication and the second support indicated in the access control indication;
• and
• communicate with the network entity in response to a mode of operation of the backscattered signal that is actively supported as indicated by the access control indication and the capability indication.
