Method of transmitting and receiving data in a wireless communication system and apparatus therefor

摘要

The present invention relates to a method and apparatus for transmitting and receiving data in a wireless communication. In a communication performed by a user equipment supporting a multi-RAT (multi-radio access technology), the present invention includes receiving a 1st information for identifying a 1st cooperative user equipment candidate from the 1st cooperative user equipment candidate corresponding to at least one of a plurality of cooperative user equipment candidates, transmitting the 1st information to a base station, receiving an information on at least one 2nd cooperative user equipment candidate determined among the at least one 1st cooperative user equipment candidate using the 1st information from the base station, and performing a communication of a 1st data with the base station in cooperation with the at least one 2nd cooperative user equipment candidate. Moreover, the user equipment and a plurality of the cooperative user equipment candidates support a direct communication without using an access point.

1. A method of performing a communication, which is performed by a user equipment supporting a multi-RAT (multi-radio access technology), comprising:
receiving an identifying information from at least one of a plurality cooperative user equipment candidates included in a cooperative user equipment candidate list, wherein the cooperative user equipment candidate list is updated based on the location of the user equipment; transmitting the identifying information to a base station; receiving information of a cooperative user equipment from the base station, wherein the cooperative user equipment is determined by the base station based on the identifying information; and performing data communication related to the user equipment with the base station in cooperation with the determined cooperative user equipment without using an access point, wherein a 1st radio access scheme is applied between the user equipment and the plurality of the cooperative user equipment candidates, wherein a 2nd radio access scheme is applied between the plurality of the cooperative user equipment candidates and the base station and between the user equipment and the base station, and wherein the user equipment exchanges a part of data related to the user equipment with the base station using the 2nd radio access scheme directly and another part of data related to the user equipment with the base station via the determined cooperative user equipment using the 1st radio access scheme and 2nd radio access scheme.
