Abstract
A mapping scheme between a plurality of control channel element sets and a plurality of acknowledgement channel resource sets is established. Each of the control channel element sets includes at least one control channel element, and each of the acknowledgement channel resource sets includes at least one acknowledgement channel resource. In accordance with a scheduling grant transmitted using a control channel element set selected from the plurality of control channel element sets, a data packet is transmitted via a second node to a first node. Then, an acknowledgement channel message is transmitted via the first node to the second node by using at least one acknowledgement channel resource selected from the acknowledgement channel resource set that correspond to the control channel element set used for transmitting the scheduling grant in accordance with the mapping scheme. The acknowledgement channel message may be one of a positive acknowledgement message and a negative acknowledgement message.
