The above TDM pattern can be understood to indicate to the UE that the uplink and downlink of the frequency band combination that will generate a harmonic interference do not work simultaneously, and/or the LTE uplink, the LTE downlink and the NR downlink of the frequency band combination that generates an intermodulation interference do not work simultaneously. Optionally, the above TDM pattern may be a set of binary characters, for example: [10101010], the [10101010] may indicate that the UE that receives the signaling can only transmit in Slot 0, 2, 4 and 6, that is, indicate that the available uplink resources of the UE are Slot 0, 2, 4 and 6.

The above TDM pattern can realize that the uplink and downlink of the frequency band combination where the UE will generate the harmonic interference do not work at the same time, and the uplink and downlink of the frequency band combination where the UE will generate the intermodulation interference do not work at the same time. For example, the TDM pattern may be a TDM pattern generated by the base station to avoid intra-UE interference from the UE. For example, the TDM pattern may be generated by the base station according to a scheduling result of the second base station for the UE. For the harmonic interference shown in FIG. 3, the uplink resources configured by the LTE base station and the downlink transmission of the NR base station for the UE are in different slots, so as to avoid the harmonic interference. For another example: for the intermodulation interference shown in FIG. 4, the uplink resources configured by the NR base station and the uplink transmission of the LTE base station for the UE are in different slots, so as to avoid the intermodulation interference.
