    Abstract: Embodiments of the present disclosure provide a downlink synchronization method, an apparatus, and a system, and relate to the communications field, so as to reduce downlink synchronization complexity and improve downlink synchronization efficiency. According to the downlink synchronization method, a base station sends downlink synchronization reference information to UE by using dedicated signaling or a system message, where the downlink synchronization reference information is used to instruct the UE to perform downlink synchronization in a second cell by referring to a downlink synchronization channel of a first cell; and the base station sends, in the second cell according to location information of the UE, a beam including a downlink synchronization channel to the UE, where the first cell and the second cell include an overlapped coverage area. The embodiments of the present disclosure are applied to synchronization channel sending.

    Abstract: The present invention provides a broadcast message transmission method, a base station and user equipment. The method includes: determining a resource position of a broadcast channel, wherein the broadcast channel occupies M physical resource blocks (PRBs) among m PRBs of a frequency band center of a carrier, m and M are positive integers, M is not greater than m, and m is not greater than the number of the PRBs corresponding to the system bandwidth; mapping the broadcast channel on the resource position; and sending a broadcast message through the broadcast channel. In the embodiments of the present invention, since the broadcast channel occupies M PRBs among m PRBs of a frequency band center of a carrier, by mapping the broadcast channel on the resource position and sending a broadcast message through the broadcast channel, the resource utilization rate of the carrier may be improved.

    Abstract: The present invention provides a method for transmitting downlink control information, a network side device, and a user equipment. The method includes: selecting, by a network side device, a aggregation level of a physical control channel set in a transmission subframe, and selecting the number of physical control channel candidates corresponding to the aggregation level according to the aggregation level; and sending, by the network side, downlink control information on a physical control channel candidate corresponding to the selected number. The times that blind detection is performed corresponding to the aggregation level corresponds to the number of physical control channel candidates, and therefore, when the number of physical control channel candidates is determined, the times that blind detection is performed is determined, so that the network side device and the user equipment can communicate with each other without increasing the times that blind detection is performed.
