摘要： A method, network node and wireless transceiver, for implementing iterative downlink passive intermodulation (PIM) spatial avoidance algorithms are provided. According to one aspect, a method in a wireless transceiver includes determining an uplink signal power. The method also includes determining an estimate of a downlink PIM subspace that minimizes a cost function that depends on the uplink signal power and a previous estimate of the downlink PIM subspace. The method further includes applying a correction to a downlink antenna signal to reduce the PIM, the correction being based at least in part on the estimate of the downlink PIM subspace

摘要： 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 and the at least one receive chain. 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.

摘要： A network device includes a transceiver configured to concurrently transmit signals and receive signals within a single frequency band resulting in radio-frequency signal interference. The device includes an analog canceler configured to mitigate the signal interference. The device includes a neural network that receives data that describes characteristics of the signal interference and provides coefficients for the analog canceler as outputs. The neural network-generated coefficients are applied to the analog canceler which uses them to cancel the signal interference.
