PURPOSE:To eliminate the need for block timing and to prevent a wait time from becoming long by removing a block frame and making the length of the exclusive-use area of each station optional, and performing a continuous rearrangement in one frame as one group. CONSTITUTION:The frame of a block is removed and a packet signal having optional length is sent out to an optional position in one frame. Further, the packet signal sent out of each station is rearranged in the frame so that they are continuous, so the exclusive use state of the packet is improved as shown by the (n)th frame F(n). Therefore, the possibility of the transmission of a long packet signal 63 is increased. Further, it is not necessary to set the block timing, so the packet signal does not require any distance code bit, so that data length is not limited to a block unit. |
