  • Publication number: 20250039873
    Abstract: Some aspects of the present disclosure enable a network to account for impacts of digital transmit and receive precoding at the user equipment (UE) side in the presence of UE self-interference that may occur during full duplex (FD) operation. Some aspects of the present disclosure include joint downlink (DL) node selection or beam selection, or both, and UE self-interference emulation, so that the UE is enabled with FD operation that includes receiving from one node, but transmitting towards another node. When compared with the case where the UE receives from, and transmits, to a same node, because when two separate nodes are involved and the two nodes are more physically separated, the chance of achieving higher cross-link isolation, and hence FD transmission, is higher.
