Side chain communication resource allocation method based on resource hopping

The invention discloses a side chain communication resource allocation method based on resource hopping. The method mainly solves the problems of resource conflict and communication failure caused by the fact that a user autonomously selects communication resources in an existing distributed D2D network. According to the implementation scheme, the method comprises the following steps: storing a security capability value of a user in a direct communication link establishment process; dividing the physical resources into time-frequency resource blocks through the sub-channels and the sub-frames; randomly selecting an initial time-frequency resource block, and taking the security capability value as a user feature; according to a given time-frequency hopping mode, pre-configuring communication resources for the user according to the random initial resources and the user characteristics, and recording the communication resources as an index set; and when the user needs to send data, querying the physical resource
