Abstract
Disclosed are apparatuses and methods for transmitting and receiving control information, such as downlink assignment and uplink grant, to each CC through a DCI format of a PDCCH in a wireless communication system using a plurality of CCs. Exemplary embodiments include configuration and transmission of a CC indicator for the DCI format, in order to identify a CC to which the control information transferred by each DCI format corresponds from among the CCs.
Claims71
A method for transmitting control information in a wireless communication system using two or more Component Carriers (CCs), the method comprising:
- generating identification information of 0 bit or m (m is an integer larger than 0) bits indicating a CC to which particular control information corresponds from among the CCs;
- adding the generated identification information to the particular control information;
- and
- transmitting the particular control information through a control channel.
An apparatus to transmit control information in a wireless communication system using two or more Component Carriers (CCs), the apparatus comprising:
- a control unit to identify a CC to which particular control information corresponds from among the CCs, to generate identification information of 0 bit or m (m is an integer larger than 0) bits indicating the CC, and to add the generated identification information to the particular control information;
- and
- a transmission unit to transmit the particular control information through a control channel.
A method for receiving control information in a wireless communication system using two or more Component Carriers (CCs), the method comprising:
- extracting identification information of 0 bit or m (m is an integer larger than 0) bits added to particular control information received through a control channel;
- and
- identifying a CC to which the particular control information corresponds from among the CCs by using the identification information of 0 or m bits.
An apparatus to receive control information in a wireless communication system using two or more Component Carriers (CCs), the apparatus comprising:
- a demodulation unit to demodulate received modulation symbols to extract particular control information mapped to a control channel;
- and
- a control unit to extract identification information of 0 bit or m (m is an integer larger than 0) bits added to the particular control information and to identify a CC to which the particular control information corresponds from among the CCs by using the identification information of 0 bit or m bits.
