Abstract: PURPOSE: A method for assigning the radio resource to a plurality of terminals forming a group is provided to transmit only the control information for the terminal in which the transport format or the resources is changed. CONSTITUTION: An ABS(Advanced Base Station) adds the AMS(Advanced Mobile Station) in a group(S110). The ABS transmits the group scheduling information determined by the scheduling to a plurality of AMSs belonging to the group(S120). The group scheduling information comprises the terminal indication information and the resource information. The terminal indication information directs whether the information for the radio resource allocated to the AMS is changed or not. The resource information directs the changed radio resource of the AMS.

Abstract: PURPOSE: A method for establishing a relay location is provided to set an initial parameter of the relay device and a installation location of a repeater by detecting a shadow area within a cell in a base station. CONSTITUTION: A base station detects a shadow areas based on a preamble measurement value of a terminal(S310). The base station presumes a signal strength of a terminal spot based on the preamble measured value. The base station compares a presumed signal strength with a reference signal intensity. The base station establishes an installation position of a relay covering up the detected shadow area(S320).
