INTER-RADIO ACCESS TECHNOLOGY INTERFERENCE COORDINATION FOR MULTI-STANDARD RADIO ACCESS NETWORKS

摘要

A method and system for coordinated interference suppression in a communication system. The communication system implements at least a first radio access technology via a first base station and a second radio access technology via a second base station. The first and second radio access technologies differ from one another. Information relating to an interference signal received at the first base station via the first radio access technology is received at the second base station from a first device associated with the first base station. At a second device associated with the second base station, an interfering user equipment accessing the second base station via the second radio access technology is identified. The identification is based on the information received from the first device associated with the first base station. Interference caused by the identified interfering user equipment is suppressed by the second base station.

1. A method of coordinated interference suppression in a communication system implementing at least a first radio access technology via a first base station and a second radio access technology via a second base station, the second radio access technology being different from the first radio access technology, the method comprising:
receiving at the second base station, information relating to an interference signal received at the first base station via the first radio access technology, the information relating to an interference signal including signal quality information; identifying an interfering user equipment, UE, accessing the second base station via the second radio access technology, the identifying being based on the signal quality information; and suppressing, via the second base station, an interference caused by the interfering user equipment.
