1. A method of transmitting data, the method comprising:
- transmitting a frame containing at least one data packet;
generating at least one detection packet for detecting a loss of a last data packet among the at least one data packet; and
in response to the last data packet of the frame being transmitted, transmitting the at least one detection packet so that the detection packet is transmitted subsequent to the last data packet,wherein, whether or not the last data packet is lost is determined by using the at least one detection packet.

Abstract
A method of transmitting data, the method includes transmitting a frame containing at least one data packet; generating at least one detection packet for detecting a loss of a last data packet among the at least one data packet; and in response to the last data packet of the frame being transmitted, transmitting the at least one detection packet so that the detection packet is transmitted subsequent to the data packet. Whether or not the last data packet is lost is determined by using the detection packet.

6. A method of receiving data, the method comprising:
-
receiving a frame containing at least one data packet and at least one detection packet for detecting a loss of a last data packet among the at least one data packet of the frame; determining whether or not the last data packet is lost by using the at least one detection packet; and requesting retransmission of the last data packet based on a result of the determining. - View Dependent Claims (7, 8, 9, 10)

11. An apparatus for transmitting a frame of data containing at least one data packet, the apparatus comprising:
-
a packet generator configured to generate a detection packet for detecting a loss of a last data packet among the at least one data packet; and a transmitter configured to transmit the at least one data packet and the at least one detection packet, and to, in response to the last data packet of the frame being transmitted, transmit the at least one detection packet subsequent to the last data packet, wherein, whether or not the last data packet is lost is determined by using the at least one detection packet. - View Dependent Claims (12, 13, 14, 15)
