The third and fourth mixing circuits may multiply the RF signal with the second and first signals, respectively, to generate third and fourth frequency converted signals, respectively. A first combining circuit may combine the first and third frequency converted signals, and a second combining circuit may combine the second and fourth frequency converted signals.

Abstract: Aspects of the disclosure relate to an apparatus (e.g., a user equipment (UE)) configured to operate in a full-duplex mode. The apparatus may include at least one transmit chain configured to operate within a first frequency band and at least one receive chain configured to operate within a second frequency band. The apparatus may receive coordination information that is configured to mitigate the self-interference between the at least one transmit chain of the apparatus and the at least one receive chain of the apparatus. In some examples, the received coordination information includes at least one of subcarrier spacing coordination information, beam coordination information, or slot format index coordination information. In some examples, the apparatus may transmit a first signal while receiving a second signal based on at least the subcarrier spacing coordination information, the beam coordination information, or the slot format index coordination information to mitigate self-interference.

Abstract: Methods, systems, and devices for wireless communications are described for self-interference or cross-link interference measurements at a user equipment (UE). A UE may receive configuration information from a base station that indicates one or more slot format index (SFI) values that are compatible for cross-link interference or self-interference measurements. Based on the configured SFI(s), the UE may measure interference in multiple symbols, which may be used to estimate an amount of cross-link interference or self-interference, and the UE may transmit a measurement report to the base station. The base station, based on the measurement report, may identify one or more compatible SFIs, beam pairs, or combinations thereof, for subsequent communications with one or more UEs. The interference measurements may identify cross-link interference at the UE that results from transmissions of a different UE, or may identify self-interference of concurrent communications of multiple channels at a same UE.
