Abstract
Provided is a cognitive inter-cell interference control method and apparatus. Inter-cell interference may be measured based on various methods in order to recognize an interference channel, and an appropriate interference control algorithm may be applied to the interference channel by modeling based on overhead. Accordingly, interference may be controlled.
Claims9
A communication method for a target base station in a target cell in a multi-cell communication system including the target cell and a neighbor cell, the method comprising:
- receiving, from at least one terminal in the target cell, information associated with interference from a neighbor terminal in the neighbor cell to the at least one terminal in the target cell, and location information of the at least one terminal;
- predicting interference from the target base station to the neighbor terminal based on the received information associated with the interference from the neighbor terminal to the at least one terminal and based on the location information of the at least one terminal;
- and
- performing interference control based on the predicted interference from the target base station to the neighbor terminal.
A communication method for a target terminal in a target cell in a multi-cell communication system including the target cell and a neighbor cell, the method comprising:
- measuring interference from a neighbor terminal in the neighbor cell to the target terminal;
- and
- transmitting, to the target base station, information associated with the measured interference and location information of the target terminal, using an uplink resource of the target terminal;
- wherein interference from the target base station to the neighbor terminal is predicted by the target base station, based on information associated with the measured interference and the location information of the at least one terminal.
