Abstract: The present invention provides a method, base station, and user equipment for transmitting a control channel. Grouping is performed, according to an aggregation level of the to-be-transmitted control channel, on sub-blocks in physical resource blocks configured by the base station for the to-be-transmitted control channel, then interleaving is performed, and then candidate control channels are mapped to the interleaved sub-blocks, so that any candidate control channel of the to-be-transmitted control channel is sent on consecutive time-frequency resources as possible, and meanwhile different candidate control channels are on different PRB pairs as possible. In this way, the base station may have better flexibility during actual sending of the ePDCCH, thereby not only achieving a precoding gain and facilitating better transmission of control information, but also achieving a larger scheduling gain.

Abstract: The present invention provides a signal sending apparatus, a signal detection apparatus, a signal sending and detection system, a signal sending method, and a signal detection method. The apparatus determines a time unit that is in each time window and that is used to transmit a synchronization signal, and transmits the synchronization signal in the determined time unit in each time window. Therefore, a synchronization signal is always located in a time unit that has a fixed location in each time window, so that a device at a receive end needs to perform detection only in a fixed time unit in each time window, thereby reducing complexity of designing and detecting the synchronization signal.
