Method of transmitting and receiving data in a multi radio access technology system using access point and apparatus thereof

PURPOSE: A data transmission and reception method in a multiple wireless connecting system and apparatus are provided to transmit data to a source apparatus by using one or more candidate cooperation terminals. CONSTITUTION: Plural apparatuses receive AP(Access Point) information from a neighboring AP(S1210). A base station respectively transmits a candidate cooperation apparatus role execution request to candidate cooperation apparatuses. The base station respectively receives the AP information from the candidate cooperation apparatuses(S1220). The source apparatus receives the AP information from the neighbor AP(S1230). The base station transmits information for one or more candidate cooperation apparatuses located at the neighbor AP to the source apparatus(S1250).
