Abstract
Provided is a method of transmitting control information of a base station in a mobile communication system includes obtaining scheduling information from a terminal; and transmitting at least two control channels through one down link carrier, wherein each control channel corresponds to a different uplink carrier.
Claims12
A method by a terminal in a communication system, the method comprising:
- receiving scheduling carrier information from a base station;
- identifying a first carrier associated with a transmission of control information for a data transmission on a second carrier based on the scheduling carrier information;
- and
- receiving the control information on a resource in the first carrier,
- wherein the scheduling carrier information indicates that the first carrier is an own carrier compared to the second carrier or an index of the first carrier in a case that the first carrier is an other carrier compared to the second carrier,
- wherein in a case that the scheduling carrier information indicates that the first carrier is the own carrier, the first carrier is linked to the second carrier, and
- wherein in a case that the scheduling carrier information indicates the index of the first carrier, the first carrier is not linked to the second carrier.
