Abstract:
1. A method for relaying data in a multi-hop cellular system comprising: receiving, by a terminal, from a base station a notification as to whether the terminal is decided as a candidate for a relay; measuring, by the terminal, the channel state with other terminals if the terminal is decided as the candidate for the relay; calculating a probability to be selected as the relay based upon the channel state to decide whether to be the representative candidate based upon the calculated probability; sending, by the terminal, to the base station a notification if the terminal is decided as the representative candidate for the relay; and relaying data received from the other terminals to the base station if the terminal is notified from the base station as to that the terminal is finally decided as the relay, wherein the probability is calculated according to: where p α n(cell) denotes the number of entire terminals present within the cell, and i denotes a relay candidate identifier.
