Abstract: The application relates to managing interference at the user equipment caused by femtocell base stations, such as home base stations, home E-UTRAN Node B base stations, and the like, configured with closed subscriber groups by allowing the user equipment to access a femtocell base station which would normally not allow access to the user equipment because the user equipment is not a member of the CSG being served by the femtocell base station. When a user equipment is within range of HeNB serving a CSG cell to which the user equipment is allowed access, referred to as the “allowed HeNB”, the user equipment may encounter severe interference from another, adjacent HeNB serving another CSG cell, which the user equipment may not be allowed access to, referred to as the “not allowed HeNB”, and which may have a stronger signal in terms of power than the HeNB including the CSG to which access is allowed.
