Abstract:
1. A method for reducing interference in a communication network including a first node and a first node coverage area, a second closed subscriber group (CSG) node, transmitting on a bandwidth at a lower power than the first node and located within the first node coverage area, and one or more user equipment (UE) devices located within the first node coverage area, the method comprising: receiving link quality measurement (LQM) information from the one or more UE devices; determining, based on the received link quality measurement information, if a link quality value for a first UE device of the one or more UE devices is below a predetermined link quality threshold value and, if the link quality value is below the predetermined link quality threshold value, the method further comprising: (i) determining, based on the received link quality measurement information, if the link quality value is caused by the second CSG node and, in response to determining that the link quality value is caused by the second CSG node, the method further comprising: (ii) determining if the first UE device is a member of the second CSG node and, in response to determining that the first UE device is not a member, the method further comprising: (iii) determining if the first UE device includes an interference cancellation (IC) capability and, in response to determining that the first UE device does not include an IC capability, the method further comprising: (iv) instructing the second CSG node to operate in an IC mode that mutes transmission of the second CSG node on a part of the bandwidth causing interference for the first UE device.
