FIELD [0001] The present invention relates to communication field, and particularly relates to an information indication method, the detection method and apparatus, a communication system. Background technique [0002] In the long term evolution (LTE, Long Term Evolution) system, the downlink synchronization user equipment (user equipment, UE) by detecting a synchronization signal (including frequency and symbol synchronization), acquires timing boundaries individual system frame and determining a physical cell identity (Physical Cell Identifier, PCI). For example, the network side periodically sends a synchronization signal located at two different time positions within each transmission cycle, the synchronization signal groups each contains a primary synchronization signal synchronizing signal (Primary Synchronization Signal, PSS) and a secondary synchronization signal (Secondary synchronization signal, SSS), wherein the two identical sequences PSS synchronization signal, SSS sequence is different, so that the user device can confirm the position synchronization signal in the transmission period according to the detected SSS sequence, so that a single system is known frame timing boundaries. [0003] Further, the UE only needs to detect a cell at the time of initial access synchronization signal to achieve downlink synchronization; Furthermore, in order to support mobility, the UE will continue to search the initial cell access after the neighbor cell synchronization and estimating reception quality of the cell signal, to decide whether to perform cell handover or cell reselection. [0004] It should be noted that the above description of the technical background for convenience only technical solution of the present invention will be clear and complete instructions, and to facilitate the understanding of the skilled in the art and forth. Just because these solutions are set forth in the background section of the present invention that the above technical solutions known to those skilled in the art. [0005] SUMMARY [0006] In the future wireless communication systems, for example. 5G, the new radio (New Radio, NR) system, using the radio spectrum resources higher frequencies greater bandwidth, such as centimeter waves, millimeter wave and the like to deal with the continued growth of wireless traffic and various all sorts of new business, however, will suffer severe high frequency transmission loss. To solve this problem, a large-scale antenna technology can be employed (massive MIMO), beamforming gain through a larger transmission attenuation against serious. Since the base station can only cover a single beam in one direction within the UE within the cell range, and therefore, a plurality of beams using the base station needs to transmit a synchronization signal and a time division a physical broadcast channel (Physical Broadcast Channel, PBCH), in order to ensure that all of the UE within the cell You can receive the synchronization signal and PBCH. Since the UE side search time should be as low as possible, the number of the base station transmits the synchronization signal is transmitted in a single signal period will be increased accordingly.
