Abstract: To allocate a bandwidth to a terminal, a base station in a communication system including a relay receives a bandwidth request code from the relay, and determines whether a bandwidth request code that is the same as the received bandwidth request code has been received from the terminal. In addition, when the same bandwidth request code has been received from the terminal, the base station allocates the bandwidth to at least one among the relay and the terminal.

Abstract: The present invention relates to a packet access router and a ranging method using the same in a mobile communication system. In the mobile communication system to which the packet access router is introduced, a better initial access process and a periodic ranging process are performed so as to accurately transmit data to the access point irrespective of the condition of whether an access terminal is provided in the packet access router region or not. When a ranging code is received, it is accurately determined whether the ranging code is directly received from the access terminal or it is received through the packet access router, and a method for performing a ranging control on the access terminal and a packet access router when the ranging code is transmitted to the access point through the packet access router. Therefore, the coverage of the access point is increased and the data throughput is improved.
