Abstract: A method and an apparatus for allocating ACKnowledgement (ACK)/Non-ACKnowledgement (NACK) channel resources and processing confirmation information are disclosed. The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.

Abstract: Method and apparatus are provided for mapping and detecting a control channel. For the same aggregation level, according to a signaling length of a control channel corresponding to a component carrier, a corresponding search space is determined for at least two control channels that have the same signaling length, so as to enable the at least two control channels that have the same signaling length to use the same search space. The at least two control channels having the same signaling length are mapped to the determined corresponding search space. Therefore, conflicts between the control channels are reduced, and the number of times of blind detection of the control channels is also reduced.
