Abstract:
A method for transmitting downlink signals at a source base station in a wireless communication system is disclosed. The method comprises transmitting a downlink signal to an end user and at least one relay; receiving a negative response signal from the end user; receiving a positive response signal and channel status information about a channel between the at least one relay and the end user, wherein the at least one relay overhears the negative response signal; and scheduling a specific relay having the best channel status of the at least one relay to re-transmitting the downlink signal to the end user.
