Abstract:
1. A method of determining a cooperative terminal at a base station (BS), the method comprising: transmitting, by the BS to one or more cooperative communication capable terminals, information about a time interval for periodically reporting status information; receiving, by the BS, the status information from the one or more cooperative communication capable terminals; determining, by the BS, a cooperative terminal based on the received status information, when the BS receives a cooperative communication request from a cooperation requesting terminal among the one or more cooperative communication capable terminals; and notifying, by the BS, the cooperation requesting terminal of the determined cooperative terminal, wherein the cooperative terminal transmits data of the cooperation requesting terminal to the BS by cooperating with the cooperation requesting terminal, wherein the status information comprises: first information about presence or absence of an external power source in the one or more cooperative communication capable terminals, and second information about a mobility of each of the one or more cooperative communication capable terminals, wherein when the first information of the status information indicates that the external power source is present in the one or more cooperative communication capable terminals and the second information of the status information indicates that the one or more cooperative communication capable terminals are in a fixed state, the status information is received only when the one or more cooperative communication capable terminals initially enter a cell, and wherein when the first information of the status information indicates that the external power source is not present in the one or more cooperative communication capable terminals or the second information of the status information indicates that the one or more cooperative communication capable terminals are not in the fixed state, the status information is periodically received at the time interval.
