Abstract:
This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for channel sensing with self-interference awareness for unlicensed band. A node may transmit, via a first entity of the node, at least one signal during a LBT procedure of a second entity of the node. The at least one signal may include a signal energy. The LBT procedure may be associated with a total measured interference from all detected energy sources. The node may determine 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 calculate 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.
