1. A method for wireless communication between first and second communication devices, a method comprising:

  • a. at the first communication device;

    i. detecting a periodic or quasi-periodic wireless signal;

    ii. generating information describing the wireless signal including a start time, duration of an interference interval during which the wireless signal is present and may interfere with signals transmitted to or from the first communication device, and period of occurrence of the wireless signal; and

    iii. transmitting a message to the second communication device containing the information describing the wireless signal;

    b. at the second communication device;

    i. receiving the message containing the information describing the wireless signal from the first communication device; and

    ii. scheduling transmissions of signals to the first communication device to avoid interfering with the wireless signal based on the information contained in the message.
