The present invention relates to a method in which a group of terminals receives a downlink control channel, and to a method in which the terminals make requests for bandwidth in a wireless communication system in which the same station identifier (STID) or cell-radio network temporary identifier (C-RNTI) is allocated to the group of terminals. The method, in which a group of terminals to which the same STID or C-RNTI is allocated receive a downlink control channel, comprises the following steps: receiving, from a base station, information on the STID or C-RNTI allocated to the terminals; receiving information on a time domain in which the downlink control channel for the terminals is transmitted, information on a frequency domain, or information on a search space from the base station; and decoding the downlink control channel on the basis of the information on a time domain, the information on a frequency domain, or the information on a search space, and on the basis of the STID or C-RNTI.
