Channel sensing with self-interference awareness for unlicensed band

An apparatus for wireless communication at a first node, comprising:

• memory;
• and
• one or more processors coupled to the memory, wherein the one or more processors are configured to:
• receive, from a second node, at least one signal during a listen before talk (LBT) procedure of the first node, wherein the at least one signal includes a signal energy, wherein the at least one signal is included in a transmission that does not include a transmission gap, wherein the LBT procedure is associated with a total measured interference from all detected energy sources, and wherein the LBT procedure is associated with a sensing slot that includes a measurement window;
• determine, during the transmission, an interference at the first node based on the signal energy of the at least one signal transmitted from the second node;
• and
• calculate, within the sensing slot and after the measurement window, additional interference from at least one other source based on a difference between the total measured interference from all detected energy sources and the interference determined based on the signal energy of the at least one signal.

A method of wireless communication at a node, comprising:

• transmitting, via a first entity of the node, at least one signal during a listen before talk (LBT) procedure of a second entity of the node, wherein the at least one signal includes a signal energy, wherein the at least one signal is included in a transmission that does not include a transmission gap, wherein the LBT procedure is associated with a total measured interference from all detected energy sources, and wherein the LBT procedure is associated with a sensing slot that includes a measurement window;
• determining, during the transmission and via the second entity of the node, a self-interference at the second entity of the node based on the signal energy of the at least one signal transmitted via the first entity of the node;
• and
• calculating, within the sensing slot and after the measurement window and via the second entity of the node, an interference from at least one other source based on a difference between the total measured interference from all detected energy sources and the self-interference determined based on the signal energy of the at least one signal.
