Method and a device for selecting a return path

Abstract

The embodiment of the invention provides a method and a device for selecting a return path, wherein, the method for selecting the return path comprises the following steps: determining all the returnpaths of the small base station for each small base station of all the small base stations; determining the return paths of the small base station for each small base station. As for each return pathof all return path, that instantaneous transmission rate of the link on the return path is kept constant, the transmission time of the link on the return path is adjust, and the path transmission rateof the return path is determined to be the maximum. The return path with the highest transmission rate is selected as the optimal return path. By adjusting the transmission time of the link on the return path, the embodiment of the invention selects the return path with the largest transmission rate of the path as the optimal return path, and the path transmission rate of the optimal return pathis increased, so that the efficiency of the small base station using the optimal return path to transmit data can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for selecting a backhaul path. Background technique [0002] With the widespread popularity of smart terminals, the amount of data is increasing exponentially. Such as figure 1 shown in figure 1 The millimeter-wave ultra-dense network includes: macro base stations, gateways, and small base stations; small base stations connect to macro base stations through gateways to provide network services for smart terminals; some small base stations need other small base stations as relays because they are far away from macro base stations. Connect to a macro base station. The connection line between the gateway and the small base station, and between the small base station and the small base station is called a link; the link connection between the small base station and the macro base station constitutes a backhaul path. [0003] In the prior...

AI Technical Summary

Problems solved by technology

Since some small base stations require a large amount of data when transmitting data, the path transmission rate of the optimal backhaul path is often lower than the path transmission rate of the other backhaul paths of the small base station, and the small base station transmits data through the optimal backhaul path Therefore, in the prior art, the efficiency of small and medium-sized base stations using the optimal backhaul path to transmit data volume is not high
