Abstract

One or more embodiments of the invention provide a secure communication method, system and device for a robust physical layer, and a storage medium. The method comprises the following steps: acquiring communication data; establishing a constraint model according to the communication data; determining a constraint problem based on a time delay tolerant system; the constraint problem is optimized using the constraint model to perform secure communications. According to the method, the downlink signal beams and the AN vectors of the macro base station and the micro base station are designed through joint optimization, so that interference in the network is more deflected to a receiving end of an eavesdropper, the receiving performance of the eavesdropper is reduced, and compared with a traditional physical layer security scheme, the robustness and stability of network security are remarkably improved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of communication technologies, and in particular, relate to a robust physical layer secure communication method, system, device, and storage medium. Background technique [0002] 3GPP, ITU-R and other international standardization organizations pointed out that in order to realize the wireless access of massive mobile devices and the transmission requirements of large-capacity wireless traffic in the future, a direct and efficient method is to use the traditional macrocell base station (MacrocellBase Station, MBS) Low-power small cells are reasonably superimposed and deployed within the coverage area to form heterogeneous networks (Hetergeneous Networks, HeNets). The random and flexible site deployment in the heterogeneous network can expand the coverage area of ​​the traditional single-layer macrocell, and can solve the problems of poor quality of service (QoS) at the edge of the cell a...
