1. An apparatus comprising:

  • at least one processor; and

    at least one memory for storing instructions to be executed by the processor, wherein the at least one memory and the instructions are configured to, with the at least one processor, cause the apparatus to at least;

    conduct a procedure associated with setting up a spectrum cooperation relationship, in which a spectrum used for communication by a second communication network is allowed to be shared by at least one access network element of a first communication network;

    receive and process control information indicating an establishment of a spectrum cooperation relationship between the first communication network and the second communication network;

    establish, on the basis of the control information, a communication connection path to the second communication network, wherein the at least one access network element of the first communication network acts as a communication element of the second communication network;

    request a grant of a secondary spectrum usage based on the established spectrum cooperation relationship from the second communication network by causing a transmission of a grant request message via the established communication connection path; and

    receive and process a response to the grant request message from the second communication network, wherein the response is information associated with a spectrum of the second communication network granted for the secondary spectrum usage and information related to usage conditions.
