Abstract: An LAA-based wireless transmission access method is disclosed including: acquiring, by a BBU, a signal format corresponding to an LBT startup indication, and delivering a corresponding LBT startup indication message; distributing, by a bridge unit, the startup indication message to an RRU; performing, by the RRU, spectrum scanning according to the signal format to obtain idle/busy state information of an unlicensed spectrum in the signal format, and reporting the same to the BBU via the bridge unit; determining, by the BBU, a preemptable unlicensed spectrum in the signal format according to the idle/busy state information, and delivering an occupancy message; delivering, by the bridge unit, the occupancy message to the RRU; determining, by the RRU, a signal source of the signal format in the occupancy message; if the signal source is a different manufacturer, switching to an intermediate radio frequency processing channel of a different manufacturer for transmission.

Abstract: Provided are a data transmission method and device, which relate to the field of communications. The method includes: when data is transmitted between an REC and one or more REs, arranging extended control words of the one or more REs in a plurality of superframes, wherein connotations of the extended control words at a same position in different superframes are different, and sending the plurality of superframes to an opposite end. By arranging extended control words of one or more REs in a plurality of superframes and different connotations of the extended control words at the same position in different superframes, the solution solves the problem that the requirements cannot be satisfied due to the limited number of control words in the protocol, and has the beneficial effect of increasing control words in the protocol.

Abstract: The present disclosure provides a clock synchronization method and a clock synchronization apparatus. Herein the method includes: a physical layer device acquires a synchronization message used for a device to be synchronized to implement clock synchronization; and the physical side device transmits the synchronization message to the device to be synchronized. By means of the abovementioned technical solution provided by the present disclosure, the problems of small user capacity of the load and high synchronization cost resulted from the clock synchronization method in existing technologies are solved, the insufficient user capacity of the load caused by the limit of the CPU architecture is avoided, and the bandwidth resource of the Ethernet is utilized to the maximum extent.
