    Abstract: A method and apparatus for transmitting and receiving mobile data based on an ASR is provided. The mobile data transmission method of a first mobile terminal including transmitting a dRTS frame and creating an ASR list; performing channel access to a certain channel based on an ASR back-off process; transmitting an srDATA frame from the certain channel to a second mobile terminal based on the ASR list; and receiving an srACK frame from the second mobile terminal in response to the srDATA frame, wherein the certain channel is a channel to/from which a third mobile terminal transmits and receives a data frame, the srDATA frame and data frame are transmitted from the certain channel at a certain point, and the ASR list is information on a mobile terminal that does not collide with the data frame when the first mobile terminal transmits the srDATA frame and receives the srACK frame.

    Abstract: A source station for synchronization of transmission and reception of data in a cooperative communication system includes a first receiver to receive, from a destination station, a first request frame including information regarding a first point in time when a first response frame is to be transmitted; a first transmitter to transmit the first response frame to the destination station, at the first point in time; a second transmitter to transmit, to a relay station, a second request frame including information regarding a second point in time when a second response frame is to be transmitted; a second receiver to receive the second response frame transmitted by the relay station at the second point in time; and a time estimator to estimate a first propagation delay time between the source station and the relay station, based on a time in which the second response frame is received.
