Apparatus and method for avoiding interference for in-device coexistence

A network device, comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors and storing programming instructions for execution by the one or more processors to cause the network device to:
• transmit and receive signals to and from a user device over a first range of frequencies;
• send an indication of a candidate affected frequency range in the first range of frequencies to the user device;
• and
• receive from the user device an indication of one or more frequency ranges in the first range of frequencies that are affected by interference,
• wherein the one or more frequency ranges are respective sub-sets of the first range of frequencies.
