Techniques for reporting sub-band full-duplex (sbfd) capability updates

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:
• communicate a signal between the network entity and a user equipment (UE) in accordance with a first duplexing mode that is based at least in part on a sub-band full-duplex capability of the UE;
• and
• obtain a message comprising information indicative of an update pertaining to the sub-band full-duplex capability of the UE, wherein the update is based at least in part on a channel impulse response associated with communicating the signal, and wherein the update identifies a second duplexing mode for wireless communication by the UE.

A method for wireless communication by a user equipment (UE), comprising:

• communicating a signal using a first duplexing mode in accordance with a sub-band full-duplex capability of the UE;
• performing one or more measurements on the signal to obtain a channel impulse response associated with communicating the signal;
• and
• transmitting a message comprising information indicative of an update pertaining to the sub-band full-duplex capability of the UE, wherein the update is based at least in part on the channel impulse response and identifies a second duplexing mode for wireless communication by the UE.
