Abstract: Systems and methods for enabling in-device coexistence (IDC) are provided. In an embodiment, IDC interference is detected and determination is made whether or not the IDC interference can be remedied using an internal user equipment (UE) solution that does not involve the cellular network. If not, a preferred IDC solution is determined by the UE and sent to the cellular network in an IDC indication. The cellular network responds to the IDC indication with a network-identified IDC solution, which may or may not correspond to the preferred IDC solution. The UE can apply the network-identified IDC solution to remedy the IDC interference.

Abstract: A method and apparatus relate to coexistence of multiple RF subsystems on a communication device. An apparatus may include a plurality of radio frequency (RF) subsystems configured to receive or transmit communication signals; and an interface for communication between a first RF subsystem of the plurality of RF subsystems and at least a second RF subsystem of the plurality of subsystems. The first RF subsystem can be configured to generate a timing offset for a coexistence signal, the timing offset being indicative of a difference between a time of generation of a signal and the time of an event associated with the signal. The timing offset can comprise a fixed offset generated based on at least one of a reference time from a periodic interrupt or direct access of a timer; and an offset adjustment based on a distance between the apparatus and a base station associated with the first RF subsystem.
