摘要： PROBLEM TO BE SOLVED: To enhance communication efficiency.SOLUTION: A communication device 30 comprises: a slot assignment section 31; and a packet buffer 32. Upon receiving a packet transmitted by a slot assigned in an immediately preceding group, the slot assignment section 31 converts the slot number of that slot into its own communication slot number corresponding to its own group. A packet buffer 32 stores its own communication slot number and the packet in pair. When transmitting a packet, the slot assignment section 31 takes out a packet from the packet buffer 32, selects its own communication slot number, and assigns a slot having its own communication slot number to the packet. When not selecting its own communication slot number, the slot assignment section selects a slot number that is later in time than its own communication slot number, and having a smallest time difference therefrom, and then assigns a slot having a selected slot number to the packet.
