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: Embodiments of the present application provide a synchronization method and a base station. In the embodiments of the present application, a first base station receives, on at least one part of channels in a receiving band supported by the first base station, at least one first downlink synchronization signal sent by at least one second base station, and selects a first downlink synchronization signal from the at least one first downlink synchronization signal, to enable the first base station to execute time synchronization according to the selected first downlink synchronization signal, which can avoid a problem in the prior art of low reliability of time synchronization caused by low availability of a GPS signal, and relieve interference suffered by a base station from another base station caused by a problem of asynchronous receiving and sending time or inaccurate time synchronization, thereby improving signal quality of an air interface.
