Abstract
A device and method for handling HARQ feedback in a mobile communication system are disclosed. The HARQ feedback handling method includes: analyzing a control message from a base station to recognize presence of HARQ feedback relationships between downlink carriers and uplink carriers; determining an uplink carrier (a downlink carrier) to support HARQ feedback in response to downlink traffic (uplink traffic) sent through a downlink carrier (an uplink carrier); and sending (receiving) HARQ feedback through the determined uplink carrier (downlink carrier).
Claims20
A method performed by a terminal in a wireless communication system, the method comprising:
- receiving uplink resource allocation information for a first cell;
- transmitting uplink data based on the uplink resource allocation information through an uplink of the first cell;
- receiving information for a retransmission of the uplink data through a downlink of a second cell in case that the uplink resource allocation information for the first cell is received through the downlink of the second cell;
- and
- receiving the information for the retransmission of the uplink data through a downlink of the first cell in case that the uplink resource allocation information for the first cell is received through the downlink of the first cell.
A terminal in a wireless communication system, the terminal comprising:
- a transceiver;
- and
- a controller configured to:
- receive, via the transceiver, uplink resource allocation information for a first cell,
- transmit, via the transceiver, uplink data based on the uplink resource allocation information through an uplink of the first cell,
- receive, via the transceiver, information for a retransmission of the uplink data through a downlink of a second cell in case that the uplink resource allocation information for the first cell is received through the downlink of the second cell, and
- receive, via the transceiver, the information for the retransmission of the uplink data through a downlink of the first cell in case that the uplink resource allocation information for the first cell is received through the downlink of the first cell.
A method performed by a base station in a wireless communication system, the method comprising:
- transmitting uplink resource allocation information for a first cell;
- receiving uplink data based on the uplink resource allocation information through an uplink of the first cell;
- transmitting information for a retransmission of the uplink data through a downlink of a second cell in case that the uplink resource allocation information for the first cell is transmitted through the downlink of the second cell;
- and
- transmitting the information for the retransmission of the uplink data through a downlink of the first cell in case that the uplink resource allocation information for the first cell is transmitted through the downlink of the first cell.
A base station in a wireless communication system, the base station comprising:
- a transceiver;
- and
- a controller configured to:
- transmit, via the transceiver, uplink resource allocation information for a first cell,
- receive, via the transceiver, uplink data based on the uplink resource allocation information through an uplink of the first cell,
- transmit, via the transceiver, information for a retransmission of the uplink data through a downlink of a second cell in case that the uplink resource allocation information for the first cell is transmitted through the downlink of the second cell, and
- transmit, via the transceiver, the information for the retransmission of the uplink data through a downlink of the first cell in case that the uplink resource allocation information for the first cell is transmitted through the downlink of the first cell.
