    摘要: Disclosed is a method for transmitting and receiving a signal in a communication system, and a system for supporting the method. To this end, a first communication system transmits data during a first time slot and receives data during a third time slot, and a second communication system, differing from the first communication system, transmits data during a second time slot and receives data during a fourth time slot. The first and second time slots are defined by downlink frame transmission intervals which exist in the entire frame transmission interval allocated for the first communication system, and the third and fourth time slots are defined by uplink frame transmission intervals which exist in the entire frame transmission interval allocated for the first communication system, wherein the first to fourth time slots do not overlap each other.

    摘要: A method for transmitting/receiving data in a communication system using multiple frequency bands. The transmission method includes fragmenting a desired transmission Service Data Unit (SDU) in units of Packet Data Units (PDUs); and transmitting the fragmented PDUs over at least two frequency bands among the multiple frequency bands. Each of the multiple frequency bands is supported by a system having backward compatibility with a legacy system. The reception method includes decrypting a wireless resource (MAP) allocated separately for each of the frequency bands to extract fragment information therefrom; and receiving PDUs over the frequency bands separately, and restoring the SDU according to fragment information corresponding to the corresponding frequency band.
