Patent ID: 8498228

Claim:
A method of signal transmission and reception by a transmitter 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 a link comprising fewer sub-frames to correspond to at least one sub-frame within a link comprising more sub-frames, considering whether the downlink and the uplink comprise different numbers of sub-frames or not; transmitting and receiving signals to and from a receiver through the downlink sub-frames and the uplink sub-frames according to the 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 a downlink sub-frames through which control information and the data burst have 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 a time slot index within the link comprising fewer time slots corresponds to a time slot index within the link comprising more time slots based on the signal transmission/reception corresponding relation.
