Abstract

Exemplary methods for coordinating inter-cell interference in a heterogeneous network comprising a macro cell and at least one small cell include obtaining, with regard to a terminal device in a small cell, a type of interference from the macro cell to the small cell, and determining a relationship between a number of uplink subframes and a number of downlink subframes in a current subframe configuration used in the macro cell. The methods also include allocating protected subframes for the terminal device according to the obtained type of interference and the determined relationship, and scheduling transmission in relation to the allocated protected subframes in the macro cell.
