Claim:
1. A communication method of master base station for device-to-device (D2D) in a multi-hop network including multiple heterogeneous cells, comprising: configuring a network topology using at least one cooperating base station to communicate between devices included in the multiple heterogeneous cells; selecting multiple device pairs, each including a transmission device and a reception device, to communicate with one another from among the devices included in the multiple heterogeneous cells; and selecting at least one cooperating base station to communicate between the multiple device pairs; collecting information including at least one of a change of service quality required by the transmission device and the reception device, a change of service quality provided by at least one cooperating base station, and a change of a channel state in the network; switching the network topology based on the collected information; changing the at least one cooperating base station to include another base station based on the collected information; creating an association between multiple device pairs and at least one cooperating base station based on configuring the network topology; and determining a cooperation context for communication between the multiple device pairs, wherein the master base station dynamically coordinates a configuration of the cooperating base station to provide for their cooperation to aid in communication among the devices.
