Communication method and apparatus for device-to-device (D2D)

摘要

Provided are a communication method and apparatus for device-to-device (D2D). More particularly, the communication method for D2D includes configuring a network topology using at least one cooperating base station to communicate among devices included in multiple heterogeneous cells, creating an association between multiple device pairs and at least one base station based on configuring the network topology, and determining a cooperation context for communication among the multiple device pairs is provided. The communication apparatus carries out such a method.

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.
