Abstract:
1. A packet transmission apparatus for transmitting a packet, the packet transmission apparatus comprising; a Media Access Control (MAC) control unit which determines a type of packet to be transmitted, and sets the packet to indicate an acknowledgement policy and a retransmission policy with respect to the packet; and a communication unit which transmits the packet, wherein the acknowledgement policy comprises information about whether an acknowledgement packet is allowed to be transmitted, and the retransmission policy indicates whether a packet retransmission is performed, wherein the packet comprises a time-dependent packet and a time-independent packet, wherein the MAC control unit sets the time-dependent packet so an acknowledgment packet with respect to the time-dependent packet is not generated, wherein the MAC control unit inserts a bit into the time-dependent packet, and wherein the bit indicates that retransmission of the time-dependent packet is prohibited, and wherein the MAC control unit sets the time-independent packet so an acknowledgment packet with respect to the time-independent packet is generated.
