Abstract
Provided is an uplink feedback channel allocation method and apparatus used to feedback data to indicate whether data packets corresponding an enhanced physical downlink control channel (E-PDCCH) were successfully decoded. A terminal may use an additional resource area of an uplink feedback channel or may use an empty resource area of the uplink feedback channel to which feedback information of a data packet corresponding to a physical downlink control channel (PDCCH) is not allocated, to perform feedback.
Claims20
A communication method of a terminal, the method comprising:
- receiving control information including an offset and resource information of data;
- receiving the data based on the resource information;
- determining a resource of feedback information for the data based on the offset;
- and
- transmitting the feedback information using the resource,
- wherein the control information is received in an enhanced-physical downlink control channel (E-PDCCH).
A communication method of a base station, the method comprising:
- transmitting control information including an offset and resource information of data;
- transmitting the data;
- and
- receiving feedback information for the data,
- wherein a resource of the feedback information is determined based on the offset,
- wherein the control information is transmitted in an enhanced-physical downlink control channel (E-PDCCH).
A terminal comprising:
- a receiver configured to receive control information including an offset and resource information of data, and to receive the data based on the resource information;
- a controller configured to determine a resource of feedback information for the data based on the offset;
- and
- a transmitter configured to transmit the feedback information using the resource,
- wherein the control information is received in an enhanced-physical downlink control channel (E-PDCCH).
A base station comprising:
- a transmitter configured to transmit control information including an offset and resource information of data, and to transmit the data;
- and
- a receiver configured to receive feedback information for the data;
- wherein a resource for the feedback information is determined based on the offset,
- wherein the control information is received in an enhanced-physical downlink control channel (E-PDCCH).
