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 is an information backhaul method, which is applied to a networking unit in a network system. The network system includes multiple stages of networking units that are cascaded, and each of the multiple stages of networking units includes multiple optical ports. The information backhaul method includes: acquiring cascade information of a networking unit in a current stage, where the cascade information of the networking unit in the current stage includes optical port information and identification information of the networking unit in the current stage; and feeding back the cascade information of the networking unit in the current stage. Further provided are a data allocation method, a networking unit, a data allocation controller, a network system and a computer-readable storage medium.

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 disclosure discloses a method and system for switching wireless devices in a looped network.
