Abstract
A method of wireless communication includes monitoring coexistence issues among supported radios in a User Equipment (UE). The method includes configuring a UE with first and second filter configurations. The first filter configuration covers a first frequency band, for example a portion of the ISM band. The first filter configuration may be wider than the second filter configuration, which excludes a portion of the first frequency band that is adjacent to a proximate second frequency band, for example LTE Band 7 or LTE Band 40. The UE selects between the first and second filter configurations based on the frequency of a first UE event. If the UE event is in a frequency in the adjacent portion excluded by the second filter configuration, the UE arbitrates depending on event priority. The second filter configuration may be chosen to reduce or minimize arbitration.
