Method and system for mitigating interference among femtocells via intelligent channel selection

摘要

Aspects of a method and system for mitigating interference among femtocells via intelligent channel selection are provided. In this regard, signals which may interfere with cellular communications between a femtocell and a cellular communication device may be detected via the femtocell. Based on the detection, the femtocell may be configured to transmit and/or receive signals on one or more frequencies and/or channels. The one or more frequencies and/or channels may be determined in the femtocell and/or in a network management entity. Detecting interfering signals and configuring the one or more femtocells may occur periodically, upon installation of a femtocell, upon power-up of a femtocell, and/or upon command from a network administrator. The results of the detection may be communicated to one or more other femtocells and/or to a network management entity.

主权项

1. A method for communication performed by a femtocell that is one of a plurality of femtocells that form a network, the method comprising:
receiving a hierarchy, the hierarchy defining a priority of the femtocell with respect to other femtocells in the plurality of femtocells; detecting a presence of an interference signal operable to interfere with a prospective cellular communication transmitted to, or received from, the femtocell; measuring a characteristic of the interference signal; determining a frequency or channel of a cellular signal based on the measured characteristic and the priority of the femtocell within the hierarchy; and configuring a transmitter or a receiver of the femtocell to respectively transmit or receive the cellular signal on the determined frequency or channel.
