  • METHOD OF LOW-DUTY MODE OPERATION OF FEMTOCELL BASE STATION
    Publication number: 20120157131
    Abstract: A method of setting a cycle of a low-duty mode in a femto base station is provided. The cycle of the low-duty mode has a pattern in which an available interval and an unavailable interval repeatedly appear, and the available interval is set to include a paging listening interval of a paging cycle. A method of setting a cycle of a low-duty mode in a femto base station having a service area overlapping with that of a macrocell is provided. An unavailable interval is set by taking the overlapping degree of the service area of the femto base station with the macrocell into consideration. A method of setting a cycle of a low-duty mode in a plurality of femto base stations operated in the low-duty mode is provided. The same cycle can be set for a plurality of base stations.
