Abstract
An apparatus for coordinating radio activities of different radio access technologies (RATs) includes a first RAT module, a second RAT module and an arbiter. The first RAT module receives and transmits radio frequency (RF) signals from and to a first cellular network through an antenna, and synchronizes transceiving timings with the first cellular network using a first clock. The second RAT module receives and transmits RF signals from and to a second cellular network through the antenna, and synchronizes transceiving timings with the second cellular network using a second clock. The arbiter coordinates a first radio activity requested by the first RAT module and a second radio activity requested by the second RAT module to avoid radio activity collision by using a third clock.
