Abstract
Methods and systems for managing resources in femtocells are disclosed. One method includes transmitting at least one frame including a first zone of resources on which a set of base stations including at least one femtocell base station and base stations that are adjacent to the femtocell base station implement transmission of signals to impose interference. The one or more frames further includes a second zone dedicated for measuring throughput of mobile stations served by the femtocell base station without interference. The mobile stations are categorized by determining throughputs of the mobile stations with interference based on the transmission of signals on the first zone. Resources of at least one additional frame are configured based on the categorization. Further, the additional frame(s) are transmitted in a cell of the femtocell base station in accordance with the configuration.
