A method of signal transmission and reception by a base station in a wireless mobile communication system using a super-frame, the method comprising: determining a signal transmission/reception corresponding relation between downlink sub-frames of a downlink and uplink sub-frames of an uplink, the super-frame comprising a plurality of frames, each frame comprising a plurality of downlink sub-frames and a plurality of uplink sub-frames, the signal transmission/reception corresponding relation enabling each sub-frame within the link comprising fewer sub-frames between the uplink and the downlink to correspond to at least one sub-frame within the link comprising more sub-frames between the uplink and the downlink, transmitting and receiving signals to and from a mobile station through, respectively, at least one downlink sub-frame and at least one uplink sub-frame according to the determined signal transmission/reception corresponding relation, receiving feedback, in response to a transmitted data burst, through at least one uplink sub-frame of a first frame corresponding to downlink sub-frames through which the data burst has been transmitted according to the signal transmission/reception corresponding relation; and when the feedback is a Non-ACKnowledgement, NACK, response, retransmitting the data burst through at least one downlink sub-frame of a second frame corresponding to said at least one uplink sub-frame of the first frame according to the signal transmission/reception corresponding relation, wherein the signal transmission/reception corresponding relation is determined by u = floor d M / N, wherein d indicates a sub-frame index within the link comprising the more sub-frames, u indicates a sub-frame index within the link comprising the fewer sub-frames, M indicates a number of sub-frames within the downlink, N indicates a number of sub-frames within the uplink, and the floor function has a value obtained by rounding down decimals of a value obtained from a calculation within a parenthesis. determining a signal transmission/reception corresponding relation between downlink sub-frames of a downlink and uplink sub-frames of an uplink, the super-frame comprising a plurality of frames, each frame comprising a plurality of downlink sub-frames and a plurality of uplink sub-frames, the signal transmission/reception corresponding relation enabling each sub-frame within the link comprising fewer sub-frames between the uplink and the downlink to correspond to at least one sub-frame within the link comprising more sub-frames between the uplink and the downlink, transmitting and receiving signals to and from a mobile station through, respectively, at least one downlink sub-frame and at least one uplink sub-frame according to the determined signal transmission/reception corresponding relation, receiving feedback, in response to a transmitted data burst, through at least one uplink sub-frame of a first frame corresponding to downlink sub-frames through which the data burst has been transmitted according to the signal transmission/reception corresponding relation; and when the feedback is a Non-ACKnowledgement, NACK, response, retransmitting the data burst through at least one downlink sub-frame of a second frame corresponding to said at least one uplink sub-frame of the first frame according to the signal transmission/reception corresponding relation, wherein the signal transmission/reception corresponding relation is determined by u = floor d M / N, wherein d indicates a sub-frame index within the link comprising the more sub-frames, u indicates a sub-frame index within the link comprising the fewer sub-frames, M indicates a number of sub-frames within the downlink, N indicates a number of sub-frames within the uplink, and the floor function has a value obtained by rounding down decimals of a value obtained from a calculation within a parenthesis. wherein the signal transmission/reception corresponding relation is determined by u = floor d M / N, wherein d indicates a sub-frame index within the link comprising the more sub-frames, u indicates a sub-frame index within the link comprising the fewer sub-frames, M indicates a number of sub-frames within the downlink, N indicates a number of sub-frames within the uplink, and the floor function has a value obtained by rounding down decimals of a value obtained from a calculation within a parenthesis.
