Abstract: Methods, systems, and devices for wireless communications are described. The described techniques generally provide for a wireless device (e.g., a user equipment (UE), a network entity) to use a set of resources for mitigating self-interference when communications in a full-duplex mode. For example, a UE may request a set of resources for performing a self-interference mitigation procedure. The UE may receive a configuration of the requested set of resources and transmit one or more self-interference measurement signals via the set of resources (e.g., in the absence of transmissions by other devices). In some examples, a network entity may transmit an indication of periodic resources, semi-persistent resources, or both, for a self-interference mitigation procedure performed by the network entity. In response, one or more UEs may cancel uplink transmissions that overlap with the indicated resources, such that the self-interference mitigation procedure is performed in the absence of uplink signals.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications device (e.g., a user equipment (UE) and/or a network entity) operating in a full-duplex operation mode may decode received signaling based on cancelling interference from transmitted signaling with a NLIC model with inter-component carrier (CC) terms. The wireless communications device may transmit and receive signaling using overlapping time resources in the full-duplex operation mode, which may cause self-interference (SI) due to the transmitted signaling interfering with the received signaling. Thus, the wireless communication device may implement a NLIC model to reduce, or remove, the SI on a per-CC basis, while accounting for inter-CC terms. That is, the NLIC model may include inter-CC terms, or kernels, that correspond to respective CCs of the transmitted signal.
