Embodiment Construction
[0070] In the following, the present invention is further described through embodiments in conjunction with the accompanying drawings, but the scope of the present invention is not limited in any way.
[0071] The present invention provides a resource allocation technical solution (named Bipartite Graph Based Resource Allocation Scheme, BGRA algorithm) for the physical layer security scenario of a full-duplex cellular network, using this resource allocation scheme , In a scenario where there are multiple uplink users and downlink users in a full-duplex cellular network, and malicious eavesdroppers exist, the system security capacity can be improved by rationally allocating Resource Block (RB) and power resources. This resource allocation method includes the following steps:
[0072] 1) For the full-duplex cellular network, construct a Bipartite Graph according to the network topology;
[0073] 2) Calculate the weights of edges in the bipartite graph through the gradient projection-b...
