1. A method for wireless communications, the method comprising:

  • receiving, by a device comprising a Long Term Evolution (LTE) modem and an industrial, scientific, and medical (ISM) modem, over a software messaging input of the device, a coexistence policy for operation of communication resources of a first radio access technology within a user equipment (UE), in which the coexistence policy;

    describes how the first radio access technology will operate based on contemporaneous operating conditions experienced by a second radio access technology, the contemporaneous operating conditions communicated over logical lines between resources of the second radio access technology and resources of the first radio access technology, in which the first radio access technology is configured to operate in one manner in response to one coexistence policy and configured to operate in a different manner in response to a different coexistence policy, andallows the LTE modem to transmit when the ISM modem is not receiving, and the coexistence policy allows the LTE modem to receive when the ISM modem is not transmitting or to receive while accounting for interference from the ISM modem; and

    configuring, by the device, operation of communication resources of the user equipment based at least in part on at least one setting in the coexistence policy governing resource operation in response to signals received on the logical lines, in which the configuring comprises;

    setting a first logical line when the ISM modem is transmitting,assigning priority to the ISM modem on a second logical line when the ISM modem is receiving,halting transmission by the LTE modem when the ISM modem has priority on the second logical line,allowing transmission by the LTE modem when the ISM modem does not have priority on the second logical line, andallowing receiving by the LTE modem when the first logical line is not set.
