METHOD OF TRANSMITTING AND RECEIVING DATA IN A MULTI RADIO ACCESS TECHNOLOGY SYSTEM AND APPARATUS THEREFOR

摘要

The present invention relates to a wireless communication, and more particularly, to a method for a base station and a user equipment to transmit and receive data in a multi radio access technology system and apparatus therefor. According to one embodiment of the present invention, a method of performing a communication, which is performed by a user equipment supporting a Multi-RAT(Radio Access Technology, includes the steps of receiving a notification signal indicating an existence of at least one cooperative user equipment candidate from the at least one cooperative user equipment candidate for a client cooperation (CC) via a 1st radio access scheme and transmitting a 1st data to a base station using at least one cooperative user equipment connected via the received notification signal among the at least one cooperative user equipment candidate. In this case, the 1st data is exchanged between the user equipment and the at least one cooperative user equipment via the 1st radio access scheme and the 1st data is exchanged between the at least one cooperative user equipment and the base station via a 2nd radio access scheme.
