Method, mobile and base station for direct mobile to mobile communication

A method for supporting, by a base station, a mobile station to mobile station communication in a wireless communication system, the method comprising:

• receiving, by the base station, information indicating channel quality between each of one or more mobile stations and a first mobile station from the first mobile station;
• determining, by the base station, which mobile station among the one or more mobile stations is a second mobile station with which the first mobile station is to perform the mobile station to mobile station communication on the basis of the information indicating the channel quality;
• and
• transmitting, by the base station, information indicating the second mobile station, to which the first mobile station is to transmit data directly, to the first mobile station.

A first mobile station for performing a mobile station to mobile station communication in a wireless communication system, the first mobile station comprising:

• a receiver and a transmitter;
• and
• a processor configured to control the receiver and the transmitter,
• wherein the processor is configured to
• control the receiver to receive reference signals for channel estimation, which are transmitted from one or more mobile stations,
• measure channel quality between each of the one or more mobile stations and the first mobile station by using the reference signals for channel estimation,
• control the transmitter to transmit, to a base station, information indicating the channel quality between each of the one or more mobile stations and the first mobile station,
• control the receiver, from the gase station, to receive information indicating which mobile station among the one or more mobile stations is a second mobile station with which the first mobile station is to perform the mobile station to mobile station communication, and
• control the transmitter to transmit data directly to the second mobile station.

A base station for supporting a mobile station to mobile station communication in a wireless communication system, the base station comprising:

• a receiver and a transmitter;
• and
• a processor configured to control the receiver and the transmitter,
• wherein the processor is configured to
• control the receiver to receive information indicating channel quality between each of one or more mobile stations and a first mobile station from the first mobile station,
• determine, on the basis of the information indicating channel quality, which mobile station among the one or more mobile stations is a second mobile station with which the first mobile station is to perform the mobile station to mobile station communication, and
• control the transmitter to transmit information indicating the second mobile station, to which the first mobile station is to transmit data directly, to the first mobile station.
