Abstract: Provided is a method of transmitting an anisochronous packet between devices in a time-sensitive wireless network. The method includes determining whether a whole packet to be transmitted is transmittable within a residual time of a contention period (CP), when the whole packet to be transmitted is not transmittable within the residual time of the CP, segmenting the packet to be transmitted into packet fragments with a length which is transmittable within the residual time of the CP, adding packet fragment information to the packet fragments, and transmitting one of the packet fragments within the residual time of the CP.
