Abstract: When a transmitting apparatus wants to transmit a preemptable frame, the transmitting apparatus transmits a preemptable packet by a custom preamble including frame length information on a payload of the preemptable frame to the payload of the preemptable frame. A receiving apparatus determines whether a received preemptable frame is fragmented using frame length information set in the custom preamble of the received preemptable frame. As described above, since it is possible to check whether the received frame is fragmented using the frame length information set in the custom preamble, there is no need to perform CRC calculation to determine whether the received frame is fragmented as in the prior art.
