Abstract
Disclosed are apparatus and methods of adaptive frequency channel allocation adjustment to mitigate the in-device interference of simultaneous coexistence operation of multiple radio frequency operation. At least one of channel conflict tables is pre-defined in the device memory. One of the multiple radio frequency operation is prioritized, and the mobile device would request the cellular base transceiver station or the host access point to allocate a non-conflicted frequency channel with respect to the prioritized radio frequency channel. Once the prioritized communication channel changes due to handover or any other reason, the device would check the allocated channels against the pre-defined conflict channel tables and request the access point or the base station to adjust the secondary frequency channel if there exists the conflict channel.
