User clustering and resource distribution method in D2D multicast scene

The invention relates to the field of communication, and specifically relates to a user clustering and resource distribution method in a D2D multicast scene. The method comprises the steps that S1, each mobile terminal uploads data information to a base station after measurement; S2, the base station selects a proper cluster head for a content requesting user according to the data information uploaded by each mobile terminal, and forms an optimal D2D multicast cluster; S3, the base station transmits the clustering information to the content requesting user; S4, resources are distributed to the formed D2D multicast cluster, and a cellular user who meets the requirements of a cellular user and D2D multicast cluster QoS at the same time and generates the minimum interference with the D2D multicast cluster; S5, each mobile terminal carries out the data transmission after receiving the clustering and resource distribution information. The method can improve the service experience of an edge user, reduces the load
