Signal estimation for interference cancellation

A second network node for wireless communication, comprising:

• at least one processor;
• and
• memory communicatively coupled to the at least one processor, wherein the at least one processor is configured to:
• transmit, to a first victim network node, at least one of:
• signaling that indicates a characteristic of an uplink signal or an indication to perform cancellation of interference corresponding to the uplink signal;
• and
• transmit the uplink signal to a third network node or receive the uplink signal from the third network node, wherein the uplink signal is concurrently communicated with a downlink signal transmitted to the first victim network node, and wherein the uplink signal is associated with interference at the first victim network node.

A method of wireless communication performed by a first network node, comprising:

• receiving, from a second network node, at least one of:
• signaling that indicates a characteristic of an uplink signal or an indication to perform cancellation of interference corresponding to the uplink signal;
• receiving, from a third network node, a downlink signal that is concurrently communicated with the uplink signal, wherein only one of:
• the second network node is the third network node, or the uplink signal is communicated by the second network node and the second network node is different from the third network node;
• and
• performing cancellation of the interference corresponding to the uplink signal based on at least one of:
• the characteristic of the uplink signal or the indication.

A method of wireless communication at a second network node, comprising:

• transmitting, to a first victim network node, at least one of:
• signaling that indicates a characteristic of an uplink signal or an indication to perform cancellation of interference corresponding to the uplink signal;
• and
• transmitting the uplink signal to a third network node or receiving the uplink signal from the third network, wherein the uplink signal is concurrently communicated with a downlink signal transmitted to the first victim network node, and wherein the uplink signal is associated with interference at the first victim network node.
