Claim:
A method for receiving a control signal in a mobile communication system, the method comprising: transmitting, to a User Equipment (UE), a control message in which a plurality of User Specific Control Informations (USCIs) are successively arranged per type of USCI group, wherein each USCI has an index number related to a position order of the corresponding USCI in the control message, wherein the type of USCI group includes a type of USCI group for a downlink resource allocation and a type of USCI group for a downlink persistent resource allocation; transmitting, to the UE, data using a downlink resource indicated by a USCI corresponding to the UE; receiving, from the UE, an ACK (ACKnowledgement)/NACK(Negative ACKnowledgment) signal corresponding to the data, wherein the ACK/NACK signal is transmitted using an uplink resource determined by using the index number of the USCI corresponding to the UE in the control message, and transmitting, to the UE, Non User Specific Information (NUSCI) including configuration information including at least one of a position of the USCI in a logical resource region or a physical resource region, a USCI size of each type of USCI group, a Modulation and Coding Scheme (MCS) level for USCIs of each type of USCI group, a total number of USCIs of each type, and a size of total resources for USCIs of each type of USCI group.
