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.

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 interference table indicative of zones of interference among the multiple RF subsystems, the zones of interference being based on RF measurements. At least one of the RF subsystems comprises a coexistence module configured to communicate coexistence-related messages with of the other RF subsystems, the coexistence-related messages being based on the zones of interference.
