Abstract:
1. A method for setting a path by a base station in a mobile communication system, the method comprising: receiving a signal directly from a mobile terminal, and measuring a quality of a link on a direct path between the base station and the mobile terminal using the received signal by measuring the data rate and a noise level of the link on the direct path; receiving a signal via at least one relaying node, and calculating a quality of an entire relayed path from the mobile terminal to the base station via the at least one relaying node by measuring the data rate and the noise level of each link on the entire relayed path based on the signal received via the at least one relaying node; comparing the data rate and the noise level of each link on the entire relayed path with the data rate and noise level of the link on the direct path, and determining an optimal path having an optimal combination of data rate and noise level, from among the direct path and the entire relayed path; sending a relaying request message to a relaying node corresponding to the optimal path; receiving a relaying response message from the relaying node; configuring broadcast information based on the relaying response message received from the relaying node; and broadcasting the broadcast information including information on the optimal path.
